How to Reset a BIOS Password

On PCs, the BIOS (Basic Input/Output System) is updatable computer firmware designed to initialize the computer during start prior to handing control to the operating system. Due to the sensitive nature of the system settings controlled by the BIOS, a password can be set by either the computer manufacturer or the end-user. Some of the most common BIOS producers include AMI, AWARD, IBM, and Phoenix with many manufacturers making their own changes to the firmware prior to selling a computer on the open market. The common methods to reset BIOS password include: Generating a BIOS password using a hash code, entering a backdoor BIOS password, reset the BIOS password using software, reset the BIOS password using hardware, and resetting the BIOS password with vendor specific solutions.

How Does the BIOS Work?

The computer BIOS is the first programming code executed by a PC when the machine is rebooted or turned on. The computer firmware conducts a power-on self-test of the system which is responsible for identifying system hardware and initializing components such as the CPU, hard drive(s), RAM, video card, mouse, and keyboard. Once the initialization task is Dallas Semiconductor DS1687-3 Real Time Clock. This IC stores BIOS setup information, including the BIOS password.complete, the BIOS checks the boot devices in order of configured preference (traditional default setting is the computer’s hard drive). The boot loader software is executed by the BIOS once located, and control of the computer is then passed to the operating system. Functionality that can be changed by the end-user through the BIOS user interface (UI) include setting the system clock, enabling or disabling system hardware, configuring hardware, enabling or setting passwords, and choosing the order of boot devices.
Although the BIOS was originally stored on a ROM (read only memory) chip on the computer’s motherboard, today’s computers will store the firmware in flash memory or EEPROM chips that can be updated after the computer has been sold. Once Intel started producing chips for use on non-PC hardware such as Macintoshes, a successor to the legacy BIOS system was required and is called the Extensible Firmware Interface (EFI). Although EFI provides a number of improvements over the traditional BIOS, it has not yet gained market dominance on PC’s.

Is There a BIOS on Mac OS X?

Prior to the production of Mac computers using x86 or Intel chips during the later portion of the 2000’s and their use of EFI, OpenFirmware was the BIOS equivalent on all Macintosh computers. OpenFirmware provides similar functionality on a Mac as the BIOS and EFI do on other computing systems. It conducts tasks such as locating attached or installed hardware and uses environment variables to direct the boot process for the Mac. To access the interface for OpenFirm, press the power button on the mac for about 10 seconds. While pressing the power button, simultaneously depress the “CMD,” “OPT,” “O,” and “F” keys once you hear an audible “chime.” Once you are done with the required modifications in OpenFirmware, exit the interface by typing “bye”, “boot”, or “mac-boot” (depends on the version of Mac computer you are using) followed by pressing the “return” key.

How to Rest a BIOS Password By Using a Hash Code

A lot of the major computer manufacturers use a master password generated from a hash code to reset the master BIOS password. This hash code is normally calculated from a unique equipment identifier such as the Serial Number, Service Tag, System ID, or Express Service Code. On many brands of computer, the identifying code will be displayed after the BIOS password has been entered incorrectly three times in a row. On other brands, it may be printed on the computer. On some HP models of computer, the hash code will only display if the “F2” or “F12” keyboard function key is press prior to entering the incorrect password a third time.
A free service provided by Tech FAQ (other websites will charge you) is our BIOS password generation tool. The tool is designed to make a BIOS password that will work on many computer brands to include: Compaq, Dell, Fujitsu-Siemens, HP, Samsung, and Sony models. The tool has also worked for many white-label PC’s running Phoenix or Insyde BIOS. recommends end users that desire to reset the BIOS password for their respective computer try the hashcode generator before paying another company money to conduct the same task. Many times, third party companies will simply charge individuals upwards of $40 USD to obtain the same information provided for free here:

Enter the checksum/hash (without any braces) you see on the screen or printed on your PC into the textbox below and click Generate.

Finding the Backdoor BIOS Password

In addition to creating a BIOS password from a hash code, a number of BIOS manufacturers also implement an explicit backdoor password. This password will work regardless of the presence of a manually set BIOS password. The primary purpose of a manufacturer’s backdoor BIOS password is for maintenance and testing evolutions. These passwords are changed periodically by the respective company and success will vary across brand and age of computer.
The reported BIOS backdoor passwords to date include:

Manufacturer BIOS Password
Award BIOS ,01322222, 589589, 589721, 595595, 598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARD SW, AWARD?SW, AWARD_PW, AWARD_SW, AWKWARD, awkward, BIOSTAR, CONCAT, CONDO, Condo, condo, d8on, djonet, HLT, J256, J262, j262, j322, j332, J64, KDD, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOX, SYXZ, syxz, TTPTHA, ZAAAADA, ZAAADA, ZBAAACA, and ZJAAADC.

How to Reset the BIOS Password Using Software

A popular option for end users to reset the BIOS/CMOS password is to use third party software.

CmosPWD  is a free application that can be used to retrieve and decrypt the BIOS password. It also provides backup, restoral, and erasing capabilities. The program is proven to work with the following BIOS types:
Award 4.5x/4.6x/6.0
Compaq (1992)
Compaq (New version)
IBM (PS/2, Activa, Thinkpad)
Packard Bell
Phoenix 1.00.09.AC0 (1994), a486 1.03, 1.04, 1.10 A03, 4.05 rev 1.02.943, 4.06 rev 1.13.1107
Phoenix 4 release 6 (User)
Gateway Solo – Phoenix 4.0 release 6
Zenith AMI

How to Reset the BIOS Password By Removing the CMOS Battery

One of the most common methods to reset the BIOS password is to remove or discharge the battery on the computer’s motherboard. If the power to the battery is lost or drained, the BIOS configuration will be reset to the factory state with no password. System settings made to the BIOS will also be lost.
Step 1 – Turn off the computer and ensure it has no external power (ie unplug the power cable. If it has a battery, remove it).
Step 2 – Open the computer’s case or box.
Step 3 – Locate the computer’s motherboard and look for the white silver button battery on the motherboard.
Step 4 – If the battery is not soldered to the motherboard, remove it carefully and wait for approximately 30 seconds.
Step 5 – Put the computer case back together and boot the computer.
Step 6 – If the “CMOS Checksum Error-Defaults Loaded” error message is displayed, the BIOS password has been reset.
In the event the CMOS battery is soldered to the computer’s motherboard, you will want to seek a different method to reset the BIOS password on the computer.

Steps to Reset the BIOS Password Using Hardware

If the CMOS battery is soldered to the computer’s motherboard, some brands will have a jumper located on the board that can be used to reset or clear the BIOS password. The location of the jumper on the motherboard will be contained in the motherboard documentation. If you can not find documentation on which jumper will reset the BIOS password, some users will guestimate on which jumper is the appropriate by choosing the one closest to the battery for reset. Another option is to short the points of the battery connection pins to the motherboard (when there is no power being applied to the computer).

Steps to Reset the BIOS Password Using the Real Time Clock

If attempts at resetting the CMOS battery through removal or by jumper fail, another method is to reset the Real Time Clock (RTC) Integrated Circuit (IC) on the computer’s motherboard. This method will work if the RTC requires an external battery. To reset, simply remove the RTC from the motherboard socket with no power available to the computer and reseat. The RTCs reported to require external batteries include:
Dallas Semiconductor DS12885S
TI benchmarq bq3258S
Motorola MC146818AP
Hitachi HD146818AP
Samsung KS82C6818A
If the RTC contains an integrated battery, it can typically be reset by shorting two of the pins for several seconds after power has been removed from the system.

For information on how to recover an Acer BIOS password, please refer to How do I reset an Acer BIOS password?

How to Turn Off the BIOS Password

Once end-users obtain the master BIOS password for the target computer, a common task to accomplish is making the computer stop asking for the password when restarted or rebooted.
Step 1 – Restart your computer.
Step 2 – Press the BIOS access key during computer restart (F2 on many models, Tech-FAQ listing of common BIOS access keys).
Step 3 – Use the keyboard arrow keys to locate the security tab in the BIOS setup.
Step 4 – Locate the submenu that lists menu items similar to:
Supervisor password is: set
User password is: set
Step 5 – Use the keyboard arrow key to navigate to the available options and press the first password setting.
Step 6 – Enter the current BIOS password in the subsequently displayed menu prompt. Some BIOS types will ask for the password to be entered twice.
Step 7 – Change the password setting to blank, not set, etc.
Step 8 – Repeat steps 5-7 for the subsequent password options that indicate they are “set.”
Step 9 – Navigate to the BIOS “exit” menu option and choose the “save changes” menu option.
Step 10 – Continue to exit from the BIOS setup and restart your computer for the changes to take effect.

Please use the password generator tool above before asking for password in the comments.

    Hey, idk about your toshiba laptop, but i have a Toshiba Satellite a665 s6070 i7 core…
    anyhow, i forgot my pssword too…i looked around the intenet and couldnt find anything, prolly due to it being new.
    so the way i reset it is:
    1.take out the laptop battery
    2. unscrew the lid off the prossesors thing…
    3. take out both of the proccessors(or however many you have)
    4. there will be a sticker under it, peel it off.
    5. on the left hand side there should be two open connections, and by them it should say cmos
    6.just take a small wire or a clip or something and connect them.
    7.viola! youre done…put everything back together and youre done.
    8.just start up the computer and press F2 and there is no pssword :)
    -hope this helps at least someone, reply if helped

    Have no Fear!
    No more opening the Case or Laptop !!!
    If you start your PC or Laptop and you are faced with the dreaded “Password” dialog after you pressed the F2 button.

    The Acer company or any other PC company is in the Business of making money.But they know how to fix the Bios Password Issue too.
    And I will show you how it is done.
    The Acer Boys use a DOS Software called “Bios Password Cleaner”
    It’s on a bootdisk that also has a HDD Lockout Password Generator on it.
    all you need to remove the Password is the Software.
    The name is “clnpwd.exe”
    How do you get it you ask?

    Here is what you do,and it’s so easy!

    I encourage you to do this:
    1. Google it
    2. look for a file called “”
    3.If you can’t find it here is the link: hxxp://
    4. download it and unzip the file.
    5. You find more Dos files in it that you can use if you want to make a Floppy Boot disk,
    but most PC’s don’t have a Floppy Drive anymore ,so you will need a Dos 7.1 Bootdisk.
    It is a MS-DOS 7.10 LiveCD / BootCD for BIOS Flashing
    Here is a link to the Dos 7.1 Bootdisk iso file: hxxp://
    Download the Password protected file and extract it with Password “123″

    1. Use an ISO image editor to open the ISO file (I use UltraISO).
    2. Place all your DOS File “clnpwd.exe into the FLASH folder. You may want to delete the folder’s contents first.
    3. Burn ISO image to disc.
    4. Boot directly to disc.
    5. Select option 1 to launch MS-DOS.
    6. When “A:\>” appears, type “C:”.
    7. When “C:\>” appears, type “cd FLASH\”
    8. When “C:\FLASH\>” appears, type:”clnpwd.exe”
    9. Follow the on screen instructions to delete the Supervisor and or User Password by pressing 1 or 2.
    Now reboot your PC and when you press F2 the Password dialog will not appear.

    “A message given in Love leads you to the Answer.”

    Laptops are little bit more tricky: in most cases, there isn’t a reset jumper or a working default password. Still, most vendors have implemented bypass mechanisms which I reverse-engineered:

  • Ron

    so Toshiba posts on their web site that commonly the computer will not start due to a password reset issue on the cmos. They state they will no longer repair this under warranty and charge 170.00 for the cmos reset password. Something is wrong with this. Nobody informed us of this issue before we spent our money even though they knew of it.  We appreciate all you have done to help us but short of some Toshiba tech recognizing that the company is acting in poor confidence therefor volunteering the password under the table, I think we have a new target for the kids to shoot at.
    I will never again support Toshiba.
    yours in disgust

      Hi Ron,

      I’m a broke college student experiencing the same difficulties with toshiba. My laptop is a huge part of my life since so much of our class work needs to be done through the Internet.

    This worked for me. Laptop was pre loaded with Vista  and bios was password protected. I followed directions on my link and it worked like a charm. Then once booted up nothing but a black screen with a blinking cursor at top left. I then tried to use recovery cd’s to restore but would quit responding on disc one. I then used XP Pro to wipe drive and loaded new partition with XP Pro. My next step then was to use the Vista recovery cd’s again and this time it.   worked. I’m thinking made some registry problems and wiping then putting XP pro fixed and allowed for a clean recovery from cd. Hope this may help someone :)   BTW my laptop was not same model as his in video but was lucky enough to have same setup from which i believe would be the case with most models.

    I don’t know if this will help anyone, but I had to reimage my Gateway M- Seris laptop. It now has a BIOS password. Tried all the forum backdoor passwords to no avail. Finally, I just started entering random default passwords. It has a PhoenixBios.
    1234 worked for me. Hope it can help someone else.

    BIOS/RTC. If you have a non-resettable RTC try putting the IC (NOT THE WHOLE PC!) in the freezer for 12hrs. This works with Texas Instruments RTCs but shoul;d work with any with an internal battery. The cold causes the battery to supply insufficient current to maintain the settings. Allow the IC to warm up naturally before re-installing

    Hi, I have a Toshiba Qosmio laptop and it’s always worked fine till recently, instead of starting up it goes straight to a screen that says ENTER PASSWORD: ______ … when pressing F2 during the initial startup it takes me to a similar page though it says “Phoenix SecureCore(tm) Startup Utility ENTER PASSWORD: _____ …” I’ve come to understand it’s asking of a BIOS password, but I have no way of disabling bios, and any password I’ve tried has failed me. Three failed attempts and the computer kicks me and shuts off. I’ve tried looking around the web for a few weeks now trying to figure it out, calling tech support etc and well nothing has worked. This is probably the most reliable page I’ve come too yet, but I’m still quite stuck. If there’s any way you can help please message me, I will be very grateful. — Thanks!

      contact toshiba tell them you have an inherited fault. tell them they have a bios problem with your laptop.. they repaired mine as a goodwill gesture.. my laptop was 5 years old.. reason being by law you have 6 year gaurantee but have to prove after a year the fault is inherited at point of purchase. toshiba have a list on their web site with all models involved.. my model wasnt listed but they honoured the fault free at not cost.

    I’m a little confused. Using the generator above with different codes supplied by my Samsung N150 it keeps coming back with what I believe the BIOS password to be but each time it fails. If the code appears to confirm the password is correct are there any other suggestions? Thank you. As yet I have unable to satisfactorily short the RTC pins

    • Will.Spencer

      With the Samsung N150, you have have to remove the CMOS battery from the motherboard and wait for a few minutes before replacing it.

    Well, I have a Toshiba Satellite L755D-S5204 with insyde h2 bios. When I turn on the computer I tried pressing F2 or F12 to get to bios or the boot manager and instead I’m presented with a black background and a blue box that says ‘Enter Password’

    After 3 attempts, it says ‘Verify error!! System is shutting down.’

    Then it turns off. No hash codes or any error messages.Would greatly appreciate if anyone has a clue on how to fix this or go about fixing this so I can use my laptop again. Thank you!

  • squidbillier

    first try worked.. thank you so much. very helpful for laptops and you don’t want to take it a part. thanks you very much

  • marshall

    hi I have dell latitude E6420 and tag is 52hjgs1 and i need hard drive password, hope you can help.
    thanks a bunch if you can

  • another toshiba guy

    i also have a toshiba satellite (l300) and i have the same problem: there’s no hash code or message, it also shuts down after 3 attempts. it seems like some 50 people who passe by this site have or had the smae problem, as anyone any clue of what might solve it?

  • another toshiba guy

    since it was removed, ill repeat my previous message: as everyone else with a toshiba, i have this problem: i can’t find the hash codes or error message i need. the laptop just shuts down, similar to what Robert Davidson decribed. It would help if – instead of deleting a message from someone who needs help (years of work in that thing) – you, what’s the word, helped. is it spam to note that toshiba users still have no clue of how to handle the mess? Please, help me (and others like me) if you can

    ps: the user name is “another toshiba guy” because i thought many of the unsolved problems exposed here were from people with toshibas, am i wrong? is is spam to have such a name? i don’t know the etiquette in these things. forgive me if it is spam or in any if it anoys anyone. I just want to be able to enter my old pc again

    • DanielMemetic

      Comment wasn’t removed. It’s still below. Perhaps there’s a Service Number on the back of the laptop you could check?

      We aren’t official tech support. We provide hopefully useful and helpful content, and try to help with questions in the comments. We also read comments for feedback to improve our articles. Perhaps it would be a good idea to contact Toshiba or their representative about this issue?

      • GONEIL

        There is a combination of key strokes necessary to display a challenge code on a Toshiba,have done it before but can’t remember.I found the info via Google ie get/find challenge code etc…

        • WillSpencer

          Apparently it’s [ESCAPE] and then [F1] on some Toshiba’s and [CONTROL][TAB][CONTROL][ENTER] on others.

  • Skyjaxxx

    Hello! I have an Acer 5320 with the password of bios that prevents me from reinstalling windows and makes the PC unusable. I entered the error code result after 3 entries in the dialog refused BIOS Password Generator Tool, and with the generated code I unlocked the bios on the first attempt. Now I’m installing Windows. A thousand times thank you!

    Hi, everyone I’m having a problem with my daughters inspiron1018 mini dell tag #241c4r1 she got it for the school program, where if your poor and get free lunches in school you get this laptop for $65.00. Daniel maybe you can help? it says to enter an HDD password.

    • WillSpencer


      Our password generator says to try these:


  • Robtronic

    Dell Latitude E6420: CKCCFS1-1D3B

    Generator dosnt seem to work for this one.. Any got any guesses?

    • WillSpencer

      Have you tried just the first part of that number? It generates these passwords:


    • WillSpencer


      That’s an Express Service Code. The generator needs your Service Tag.

      I rewrote the text above to make this more clear.

  • tazpaul

    hello , I have tried the above generator but it wont do anything , just keeps showing what I typed in. #93v0ch1-595b. any help please thanks

    • WillSpencer


      It is showing me this: lotra658


    Hi,no action in the generator with Vaio VGN-CS36GJ challenge code DT2D-XKR7-J8TF-3R96 that I have entered.Help appreciated,thanks

    • WillSpencer

      I don’t think that the generator will work with news Toshiba’s.

      You’ll likely have to call Toshiba tech support and give them the Challenge Code.

      What is the model number of your Toshiba?

          Please help me, my friend

          • H3llas

            This is from your computer user manual:

            Remember your passwords! If you set and
            forget your User and Master hard disk
            passwords, Fujitsu Computer Systems will
            not be able to reset it. You may lose data
            and have to replace your system board or
            hard disk drive.

            Though it looks like some people found workaround

            Bad thing is it is not free.

            I am clueless without having hand on your specific model.

      In that case, you’ll either have to contact Samsung for the code or open your PC to find the pins to short.


    Hi, i need a bios password for my ASUS S400CA VIVO

    • WillSpencer


      With your ASUS, it looks like you’ll have to open up the notebook and use the Clear CMOS jumper.

      Unfortunately, the at ASUS do NOT include instructions on how to do this in the User Manual:

      So… you’ll either have to open up the device and look around or you’ll have to contact ASUS support.

  • AHM

    I forgot Bios password

    I need reset Password

    samsung NP355E4X-A02MY


    System disabled 57C818894D68993000

    please Help

    • WillSpencer


      Neither of those codes seems to be generating a password.

      Our generator worked with Samsung PC’s in the past. It *may be* that Samsung has changed their BIOS password algorithm.

      Unfortunately, Samsung did not publish a decent manual with this notebook. Here’s all we get:

      Because of this, the options are either to open the notebook and look for a RTC reset jumper or to call Samsung support.

  • Macius

    Please, generate a password Phoenix BIOS 1.04 for Laptop Active Book L55RI0 or L55R10

    After entering the password three times, an error pops block number:

    The Disabled

    Motherboard Model:
    HannStar J MV-4
    94V-0 0737

    • WillSpencer


      I’m not familiar with that model. You’ll have to figure out how to coax a hash code out of it. Then, you can put that hash code into the BIOS password generator above.

      Who is the manufacturer of that device?

      • Macius

        Active Book is a manufacturer and it comes from China has ARNO

        How to extract hash code?

        perhaps what is says on the label tailgate Laptop:

        63GL55015-20 CM-2

        SZSL55RI074400122 <—barcode

        • WillSpencer

          Neither of those are recognized by our BIOS password generator tool.

          You might be able to get a hash code by entering the wrong password three times.

          • Macius


          • WillSpencer

            That’s the error number, not the hash. :(

    • WillSpencer

      Probably you will have to open the case and short the CMOS chip.

      Advent supplies a user manual for the 7113 on the “Notebook Utility CD” that came with your system. Do you have that CD?

      Advent doesn’t seem to have a web site where you can download the manual, but since the Advent 7113 is just a rebranded Uniwill L5II you can download the manual here:

  • Matt

    I need to locate CMOS jumper for Toshiba A355-S6935 since the battery is soldered, I need to reset CMOS jumper. I’ve located the battery as in the immage below, but I don’t know where the jumper is.

    Thank you

    • WillSpencer

      Instead of searching for a jumper, I’d remove the battery to delete the BIOS settings.

      Read the article section “How to Reset the BIOS Password By Removing the CMOS Battery” for tips.

      • Matt

        Well, I didn’t want to unsoldered it. Anyway, thank you for your suggestion.

        • WillSpencer

          Ahh… from the picture I could not see that it was soldered on — it looked like it was held on just by a pressure clip.

          How about shorting the points of the battery connection pins to the motherboard (when there is no power being applied to the computer)?

          • Matt

            I did unsoldered the battery and solder it back… and also shorting the battery points, but didn’t work. Still my laptop is “dead”

          • WillSpencer

            What do you mean “dead”?

          • Matt

            Won’t power on.

          • WillSpencer

            I am confused. “Won’t power on” is not a symptom of a BIOS password problem.

          • Matt

            IT was working fine until I started to update BIOS and it took a long time. I left it on the table and when I came back it was off. Since then, it won’t turned on anymore.

          • WillSpencer

            The common slang for systems which crash during BIOS updates is “bricked”. It means the motherboard is now “functional as a brick”.

            I see a replacement motherboard on eBay for $68.95:


    • H3llas

      Try this: look for the B500 or XXX jumper, it should be somewhere around ram memory.
      Short one of those out for a couple of second… Those worked on old Toshibas.

      • Matt

        I will try this one as the last attempt to power on my laptop. Thank you for your suggestion.

        • H3llas

          Since you can’t power on your laptop, judging about comments bellow, I can say this will not work for sure. If your computer stuck while updating bios then you will need professional help to fix it.

  • Oinam

    My laptop is singtech i forgot bios password and hash code is F34D5973 , plz tell me the password

    • WillSpencer


      Try 14415100.

    Hmm. I think that one is tricky. You will need bios password unlock chip for it. Try searching on ebay, you can find those for 15-30$.

      Did you tried SKY_FOX password?

      Did you tried to short out jumpers when you turn on your notebook?

      • Marko Zivkovic

        HI H3llas,
        SKY_FOX not work :(
        Also i tried to short-on cmos jumer and start up laptop but same situation.
        When i start computer i got this screen (nr.1) .
        When i press setup i go to bios but need bios pasword : picture (nr.2)
        or when i go to resume i need other ( i dont know which) pasword..

        When i try 3-times wrong pasword i got message: System Disabled 65534 !

        I tried shortly to explain my problem ,thanks in advance for your patience.. :)

        • H3llas

          Does your Amilo has battery like in this video?

          • Marko Zivkovic

            Yes, i just tried this metod feww times .. but same situations , after i again got screen like picture nr.1 … all is same …
            I slowly lose my temper .

          • WillSpencer


            I’m confused. The picture you posted doesn’t show a BIOS password problem.

            It shows that your BIOS configuration has been lost. Press F2, confirm or configure your BIOS settings, and the message should disappear.

          • Marko Zivkovic

            When i press F2 ,i got picture nr.2 , where need bios password .
            i cant configure or confirm BIOS because always looking paswswod.
            When i press F1 i got picture nr.3 .

            very strange :(

  • kayemi

    Hi i have a smsung n150 and the code is

    • H3llas

      On a Samsung n150 netbook you reset the bios by shorting out small contacts called RTC Reset while you turning on your computer. Computer will then restart.

      RTC is located on the right side of the RAM memory utors as you can see on the picture.

      Another easier way is to remove battery and wait some time

      Which Gericom model do you have?

      • Adis

        supersonic force

        • H3llas

          This worked on another version of Gericom so maybe you can try it:

          Disconnect your notebook from power. Keep cmos battery.

          Remove the RAM cover, and on the underlying DIP switch (S3) put switch number 4 to ON for about a minute.

          • Adis

            this model dont have dip switches
            this is newer model with petium dual cpu T2050(i think)

      Try to get into the BIOS three times. Eventually it may give you a hash code that you can enter into our password generator tool above.

      If not, you’ll have to remove the CMOS battery or short a couple of contacts on the motherboard.

          Unfortunately, if those don’t work you will have to call Dell Technical Support at (800)624-9896.

        • WillSpencer

          Alternatively, if you’re comfortable opening your machine, take a look at page 35 of the E6520 Owners Manual. It should be easy to temporarily remove the coin cell battery, which will erase your CMOS settings.

      That code doesn’t appear to be valid. Please check it, making certain to note which characters are O’s and which are 0′s. Also double-check 1′s and I’s.

      If the hash code can’t be sorted out, you’ll have to remove the CMOS battery or short a couple of contacts on the motherboard.

      What happened when you put that Service Tag into our Dell Password Generator Tool above?

      Did it show you these possible passwords for your Dell?

      For Service Tag: 994x2q1

    thank you

    • WillSpencer


      That doesn’t appear to be a valid hash code.

      Please check it, paying special attention to O’s and 0′s and 1′s and I’s.

          • H3llas

            I think you will need pre-programmed bios chip soldered to your motherboard. There are people selling those chips online.

            Other then that maybe you can contact Samsung support or a store where you bought it for warranty.

          • H3llas

            p.s. Does your model have RTC reset pins near the ram utors like on this picture.


  • kimberely

    i used the tool above none worked for me… its a dell latitude 6410, i previously dismantled the whole system into several parts trying to find a specific chi to short, never found the thing, wild goose chase. I went to dell and they refuse to help me because ownership was never transferred last year when we purchased it from a private party…who I only know his first name and cannot seem to find anyone that knows his phone number…what can I do? also, do you know why a bios password would just appear after 8 months?

  • tj

    Hi, I’ve got a samsung R519 that is asking for a bios password. I tried 3 times and got the system disabled message with code 318C10060000000000 . I tried the generator and got 2 codes ‘Samsung’ and ‘p12′. Am I doing something wrong. I’ve tried both but they don’t work. Any assistance would be appreciated.

    • H3llas

      It’s just p12. Do you get different code or the same one when the system is disabled next time?

      • tj

        I got a different code the first time. It was 233201180000000000 but the generator gave me the same password p12 and it didn’t work

        • tj

          Hi, Just got it sorted. The password ‘p12′ was correct. It was the keyboard that was faulty. I connected a usb keyboard and typed in the password ‘p12′ and it worked fine. The bios password has now been cleared. Thanks for the advice.

          • H3llas

            Great to hear you sorted it out.

  • Char Brown

    Hi I have a hp pavilion dv2000 and the disabled code is 01982 I brought off a person online and iv tryd to contact the for the password but they wont contact me back so if you cauld help me out that would be great

    • WillSpencer


      Try putting the serial number from your HP into our BIOS password generator. The serial number is printed on the underside of the notebook.

      If that doesn’t work, you’ll have to open your notebook and temporarily remove the CMOS battery.

      Instructions for doing so can be found in section 5-5 (page 125) of the HP Pavilion dv2000 Notebook PC Maintenance and Service Guide:

  • Char Brown

    Willspencer..thank you I tried putting the serial number in and it came back with 2 codes but they r both too long..and the cmos battery is fastend to the laptop and I cant figure out how to get it off without breaking it

    • WillSpencer


      What is the serial number?

      The picture on page 125 of the service manual shows you how to remove the battery.

  • Char Brown

    The serial number is 2CE64

    anyone know the bios password for a advent 7302- model number:AL-096
    No # code comes up with bios password at all.

    • H3llas

      It looks like that model is writing password on EEPROM. This means that you can clear it if you can boot from CD or to OS. Try getting Ultimate Boot CD iso and burn it on CD. It used to have few password clear tools.

      • Jay Jay

        Thanks, i actually put a new hard drive in with vista preloaded so can just go on it that way have now got the password taken off was a real pain as normally this is no issue for me, very greatful for the help :)

    Need your help H3llas, been at this for days. I have a Sony Vaio PCG-71912L (VPCEH1AFX) which needs a BIOS password. I’ve tried the password generators for the older Sony Vaio but they don’t work on mine, I can’t seem to get any help(even from Sony). Using the last 7 digits of the S/N doesn’t work on mine, that is for older models. After 3 failed attempts I get a 16 digit(4×4) code that needs to be converted into a one time password. The code I currently have up is 7T73-2J6J-FP98-R7T3. Please tell me you have the new script to convert this. Any help will be greatly appreciated.

    • Sami Alam

      That last 4×4 code is no longer valid because I had to shut down the laptop. If you or WillSpencer can help then please contact me and I will generate a new code the same day you reply. As you know the code changes every time you reboot. Thanks.

      • superdave007

        Hi Sami, Any luck yet? I’ve got a newer Sony with a similar 4×4 code for onetime password that I’m stuck on. Did you get a private message with assistance or are you still stuck too?

        • Sami Alam

          Didn’t get any assistance with it but it turns out that the previous owner had set a personal BIOS password and I was able to get that from her. I hope someone is able to help you with yours, sucks not being able to do anything because of BIOS password.
