You must need to open the laptop and take out the small battery from lithium from 3.5v, for 1 minute, this will clean the information for CMOS memories, and the password, and install again. and ready.
God bless you

SOURCE: change or remove BIOS password

Hi Michael,

ready for a challenge?

This homepage hold a load of Backdoor passwords, - one of them will bypass you forgotten BIOS password. If you don’t know your type, you´ll have to try them all out, or until you hit the right one:
http://www.computerhope.com/issues/ch000451.htm




If the above doesn’t work, try this:
!BIOS, download from here:
http://www.technibble.com/downloads/misc/BIOS320.EXE

!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.
CmosPwd will recover the BIOS password for the following BIOS versions:


ACER/IBM BIOS
AMI BIOS
AMI WinBIOS 2.5
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
Toshiba
Zenith AMI
Download !BIOS and save it to your desktop. Then, open a DOS command windows by going to
Start -> Run and type: cmd
Once you see a black screen in front of you, type: cd desktop
You should now see something like: C:Documents and SettingsYourUserNameDesktop>
Now type the name of the file you just downloaded, if you haven’t changed the name just type in: bios320.exe

Use the down arrow and choose “Crackers” and then press the right arrow. Using the up and down arrows, select the BIOS that the motherboard is using and press Enter.
You should now see a menu asking what you want to crack, in most cases its the Supervisor or System Passwords you want to crack, so press the 1 key on your keyboard. It will then show you another menu asking how you want it to be cracked. Option 1 is pretty good so try that first by pressing the 1 key on your keyboard. You should now have your BIOS password.
Reboot the computer, enter the BIOS and try it out.

NOTE: Because of this applications password cracking abilities, some anti-virus software may report it as a virus/trojan. This is a false positive.

If the above doesn’t work, try this crack link:
BIOS password crack, download from here:

Good Luck

SOURCE: reset bios password or remove

The laptop password cannot be reset by removing the battery and there is no jumper for the CMOS or bios reset. You must go to Acer to obtain the master password as laptop computers have NVRAM (non-volatile RAM) that retains the password forever as an anti-theft protection. Steve Medley

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!

    What you need to do is Flash the BIOS.

    http://support.acer-euro.com/drivers/notebook/as_4315.html

    With this utility you should be able to FLASH BIOS to factory default and enter BIOS without password. Be extremely careful to follow the steps exactly, because one false move and your system could be rendered useless.

    Hope this helps

    2. Reset Password BIOS via Software.

    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.

    My acer aspire one crashed and i need help


    Below are the steps for the resetting of the password. Below the steps is the link for the service manual. On page 113 is the picture of the jumper pads that need to be "shorted" to reset the cmos.

    Steps for Clearing BIOS Password Check
    If users set BIOS Password (Supervisor Password and/or User Password) for a security reason, BIOS will ask
    the password during systems POST or when systems enter to BIOS Setup menu. However, once it is
    necessary to bypass the password check, users need to short the HW Gap to clear the password by the
    following steps:

    • Power Off a system, and remove HDD, AC and Battery from the machine.

    • Open the back cover of the machine, and find out the HW Gap on M/B as picture.

    • Use an electric conductivity tool to short the two points of the HW Gap.

    • Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the
    system till BIOS POST finish. Then remove the tool from the HW Gap.

    • Restart system. Press F2 key to enter BIOS Setup menu.

    • If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and
    try again.

    NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).

    Bios password


    You will need the BIOS password to enter the BIOS setup.
    To do a hardware reset remove the CMOS batteries for 30 minutes. Once your BIOS password is removed, you will need to press the <F2> key during POST (Power On Self Test) to enter the Acer BIOS setup.
    After you enter BIOS, go to the Boot tab and down to "Security" and make your changes there.
    If you need help with the default password, please re-post your request.
    Thanks and good luck.
