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:
If the above doesn’t work, try this:
!BIOS, download from here:
!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:
AMI WinBIOS 2.5
Compaq (New version)
IBM (PS/2, Activa, Thinkpad)
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

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.

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
