SOURCE: acer aspire 3690 bios reset

Underneath the ram (remove ram) is a jumper marked J3
short this out for a couple of seconds.

This will reset bios right back.

Boot and go straight to bios (F2) and set your options as needed there.

Eg date, time, drives,and any other options the bios needs to be able to boot the machine. When you have done make sure you SAVE then exit which will re-boot.

If you didnt mess any bios settings you should be back in business



Is this information was useful please click

SOURCE: Toshiba satellite A215-S5818 bios password

This should be able to be solved by opening the Ram bay and shorting out two solder points. Usually marked with a "xxx". The notebook should be started with these solder points shorted. Once the pc is on, it should go through the normal process without asking for a bios password. Once the pc is restarted, the CMOS password should disappear.

I need help finding my bios password


The best method to reset a BIOS password depends on what BIOS the computer has. Common BIOS's include AMI, Award, IBM and Phoenix. Numerous other BIOS's do exist, but these are the most common

Some BIOS manufacturers implement a backdoor password. The backdoor password is a BIOS password that works, no matter what the user sets the BIOS password to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time.

Please reder your manual to find which bios is yours i think most probably it will be a phoenix but you need to confirm that on manual

AMI Backdoor BIOS Passwords

Reported AMI backdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW, BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.
Award Backdoor BIOS Passwords

Resetting the BIOS Password using Software

Every system must store the BIOS password information somewhere. If you are able to access the machine after it has been booted successfully, you may be able to view the BIOS password. You must know the memory address where the BIOS password is stored, and the format in which the BIOS password is stored. Or, you must have a program that knows these things.

You can write your own program to read the BIOS password from the CMOS memory on a PC by writing the address of the byte of CMOS memory that you wish to read in port 0x370, and then reading the contents of port 0x371.

!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

Toshiba Satalite M35 x, trying to clear bios password, i never set it! Plus the keys are locked, password field will not accept anything


I copied this info from a website since it needs a very particular solution. The only time I had to use it, it worked.
Go to setup (if it lets you) and check the BIOS brand and version.
(If you cant do anything due to the password, then you need some hardware to do that). I hope this helps

Cannot boot laptop because of bios password


Easiest way to wipe clean the Bios password is as follows:
  • Perform a power drain by removing laptop battery pack and/or docking station power supply and hold power button down for 10 seconds
  • Locate the CMOS battery (usually under the smallest panel on the bottom of the laptop)
  • Remove CMOS battery for 20 minutes (20 is arbitrary can wait longer if you wish)
  • Replace CMOS battery and panel
  • Replace battery pack and/or replace to docking station
  • Power up
The Bios password should now be removed and you should be able to boot with no issues. Thank you for using Fixya and please remember to return to rate this answer.
