Unplug wall adapter from laptop. Remove battery. Remove memory cover from bottom of laptop, there should be a small watch battery in a plastic holder. Remove the battery and wait @ 10mins. Replace battery. BIOS password should be clear.

    how long for? how about trying for 30 min.

    Once your BIOS password is removed, you will need to press the
    key during POST (Power On Self Test) to enter the Acer BIOS
    setup.

How do I get into my bios when F2 won't work


Try tapping the Delete key instead.

It say here you use F2, but you have to do a complete shutdown rather than a restart. You have to keep tapping as soon as you see a logo or life!

    Fogot bios password for acer 7535g


    BIOS passwords can be reset or removed in two ways:

    1. using software 2. using hardware.

    I would first try resetting or removing using software, here are two software apps to reset or retrieve BIOS passwords.

    !BIOS - is a PC BIOS toolkit offering password removal/decrypt and BIOS settings modification/backup/restore.
    You can download it here:

    CmosPwd - Cmos password recovery tools
    http://majorgeeks.com/CmosPwd_d239.html

    You will need to create a bootable Dos, or Linux or NT cd in order to run them.

    Good Luck!

    ACER default password for Bios


    Hi,

    By default Acer wont enter any BIOS password however, if you have forgot BIOS password then you have to reset CMOS jumper setting. Please follow the below steps: Open the Laptop back panel. Locate the CMOS battrey, remove it & then with the help of a screw driver keep on pressing the terminal inside it and turn ON the computer for 10 secs and Turn Off (make sure you keep on pressing the terminal with a screwdriver while turning ON). It will short the BIOS setting. Now, fix the CMOS battrey & restart the computer. This will take care of the issue.

    Thanks and regards,
    Jitha

    Can't remember password


    BIOS password remove alternatives:

    1. Reset Password BIOS via Backdoor BIOS Password.
    2. Reset Password BIOS via Software.
    3. Reset Password BIOS via hardware.
    4. Reset Password BIOS via default manufacturers.


    OK, here is my guide to Remove Acer Bios password computer via Software. This has been done on testing machine Laptop Acer Aspire 3620/ Travel Mate 2420. Anyway, I'm not sure it will work on every Acer PC/Laptop so just consider to do at your own risk, I’m not responsible for any damages caused by this guide.

    As we know most of Acer computer (Laptop & Desktop) allow us to setup BIOS in Microsoft Windows (9x/XP/Vista) environment. Great, this is the powerful that help us to remove the BIOS password cuz all we know if we enter Setup Utility at the boot time we have only three times of filling the password and if all wrong then the system will halt.
    The program helps us to enter Acer BIOS setup in Microsoft Windows is “Acer eSettings Management” which comes with the CD when we buy Acer PC/Laptop. If you lost the CD then just come to Acer website to download the program.

    Never heard of a 'hard drive code' before.. You don't mean a BIOS password, do you?? If it is a bios password, there is most likely a switch or 'jumper pin' on the motherboard, that will reset the bios to default. That will get rid of the password. If this is not helpful, please describe what happens when you try to start the pc..? Maybe more info will help sort this out. Go to the website of the manufacturer & look for your model of pc. It will tell you how to reset the bios password, if you need further info..
