  • How to Reset an Acer BIOS Password

    Acer is a leading computer hardware manufacturer. They make desktop computers, notebooks, monitors, projectors, servers, and storage devices.

    Every Acer computer and laptop comes with a pre-installed BIOS software. This BIOS software is generally protected and secured by some password. Because it is a common tendency for any person to forget passwords, this article specifically discusses about resetting or recovering BIOS password of any Acer computer or laptop.

    Mentioned below are few ways by which an Acer’s BIOS password can be reset or recovered.

    Using Acer eSettings Management

    This method will work only if you can boot into your Acer computer. Once you boot in, you can use Acer eSettings Management to reset the BIOS password.

    Note: Installing Acer Empowering Technology is a prerequisite to use Acer eSettings Management. Both utilities can be downloaded here.

    Step 1: Open Start Menu by clicking the Start button on your desktop.

    Step 2: Go to All Programs > Empowering Technology > Acer eSettings Management.

    Step 3: Click BIOS Passwords near the footer of the screen.

    Step 4: With the Create Password or Remove Password options, you should be able to regain control.

    Reset Acer Bios Password with Acer eSettings Management

    Using Computer Hardware

    This method involves fiddling with the computer hardware and components. Proceed only if you’re confident enough to do this task. This may also void your warranty period. The steps below are mentioned for both, desktop computers and laptops.

    Step 1: Disconnect the power cord from your desktop computer or laptop.

    Step 2: Remove the cabinet cover of your desktop.

    For a laptop, turn it upside-down and remove the battery. Open the hard drive compartment by sliding the cover out. Unscrew and pull out the hard drive from your laptop.

    Step 3: Locate a coin-shaped clock battery (also known as CMOS Lithium battery) and remove it. Keep it aside for at least an hour.

    For a laptop, disconnect the tiny power lead that connects the clock battery to the motherboard. Keep it disconnected for at least an hour.

    Otherwise, you can also locate a BIOS reset jumper marked CLRP1. Move this jumper to Clear position. Let it be in this condition for at least an hour.

    Step 4: After about an hour, replace the battery in the socket or move the jumper back to the Run position.

    Step 5: Fit the cabinet cover and start your computer.

    If done right, your computer or laptop should boot up without asking for any BIOS password.

    Contacting Acer Customer Support

    Acer refuses to assist customers with BIOS password issues. The only option they discuss involves sending the laptop to them and paying a $100 fee.

    Below is a copy of an email from Acer Support:

    Thank you for contacting Acer America. I apologize for the delay in responding to your inquiry. In order to have the BIOS or hard disk password removed (This include any biometric security), the notebook will need to come in to our repair depot for password removal. This service is not covered by warranty and unfortunately there is no other recourse to remove a BIOS or HDD password from the notebook. The flat fee for BIOS password removal is $100.00 US dollars plus tax.

    Using Online BIOS Password Generator

    BIOS Password Generator Tool


    1. Most BIOS password checksums are stored on the Flash ROM. Therefore, many manufacturers display this checksum (often called ‘hash’) on the screen by keying in 3 invalid passwords.
      Example: [CNU1234ABC]
    2. Do not be scared by any system messages such as ‘System Disabled’. Just plugout all power cords, replug and restart.
    3. Enter the checksum/hash (without any braces) you see on the screen in the above textbox and click Compute.

    Do you know of any other method to reset an Acer’s BIOS password?

      Thanks for the solutions! On my Acer Aspire Switch 11 SW5-173 the password generator worked. With the generated password I could enter the UEFI as well as reset the existing password. However, I still have no idea, how the password was set and what it was. I don’t really need one. Glad, it’s gone now.

      9 May, 2017 at 2:28 am

      I just wanted to say THANK YOU!!! I was trying to show my best friend something in my UEFI and a password prompt popped up. I never remembered setting a password so then it became a guessing game. Then I got a prompt with a key, and with this page, I entered it and the Online BIOS Password Generator spit out a working password. Thank you so much for this tool!

        9 May, 2017 at 2:35 am

        Abdullah, have you tried the tool above? Your computer should have given you a key after three failed attempts, mine was 8 numbers. When I put them in the Online BIOS Password Generator, it spit out two possibilities. I picked the one for Acer/HP and used it as the password, and I was in! Make sure you change your password afterward. Good luck friend.

      On an Acer Aspire 7720 laptop that has a BIOS password, it is impossible to change or remove it, even using Acer eSettings Management (it keeps saying invalid password), even using cmos cleaner, even d/cing the clock battery for an hour (it resetted everything but the password prompt is still there when trying to access the BIOS). No checksum displayed after keying in 3 invalid passwords either. Any ideas ?

        • MégaLAG

          14 June, 2015 at 9:24 pm

          BIOS info was on EEPROM in my case, I had to upgrade the BIOS to remove the password (I took the opportunity to install a custom BIOS with much more options as well). You can feel that ACER really don’t want you to solve this issue by yourself.

          • Deviluke

            4 October, 2015 at 3:40 pm

            What custom BIOS did you use, and how did you do it? I also have the acer aspire v3-731 and I’ve tried everything to get in the BIOS.

            Hello, MégaLAG, how did you upgrade the BIOS ? I have the v5_551 and i also have the screen with ” system will halt “. Thank you.

              26 February, 2016 at 3:21 am

              Sorry for the late answer, didn’t see your comment in my comment feed. You can either get an official BIOS from ACER website (on content/drivers, then you select your laptop model, then you select BIOS/Firmware, then execute the BIOS update software), or get an unlocked one from bios-mods. Be careful to be sure the BIOS corresponds to your laptop, as it could semi-brick your pc (you’d have to flash BIOS manually from bootable usb to solve the issue).

              28 February, 2016 at 11:12 am

              Hello MégaLAG, how do you use a bootable USB-device when it’s not possible to choose a boot device (cd-rom, usb, extern HDD). I’m looking forward to your answer.

              Thank you.
