How to Bypass or Remove a BIOS Password by Removing the CMOS Battery:
The simplest way to remove a BIOS password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware.

If password appears before Windows starts, will require complete laptop dismantle to remove cmos battery for 1 hour.


If it appears just before Windows starts, go into safe mode and control panel / passwords / remove password.

The password is not on the battery it is in the volatile memory.

The battery supplies the power to the volatile memory to make sure it retains its settings.

If you have removed the Cmos battery and when you put it back the machine still has a password then the password is written into the non-volatile memory and cannot be re-set that way.

Get a hold of someone with ERD Commander and they will drop the password off in a couple of minutes

for windows xp start in safe mode

(when the computer is starting press F8 and choose safe mode)

when safe mode loads go into your control panel and make a new user restart the comuter noramlly and choose that user and then just delete the old one

the windows log on password can be deleted by:- press F8 on start up and enter safe mode and highlight start windows in safe mode, and log in windows using administrator account and go to user accounts and profiles and in the other log on account delete the password and restart windows. If you mean the bios password only removing the cmos disc shaped battery on the motherboard for 5 minutes or so can delete the password.

The only way is to clear the cmos settings. However, there is a special way to do it. First you have to take out the battery and the power adaptor from the laptop. Then you need to open the laptop and look on the main board for the cmos battery. Take it out for a few minutes, maybe 5 - 10 minutes. Then plug in the power adaptor without the cmos battery nor the laptop battery and boot the computer. It will ask you to hit F1 to either load default values or to save settings. Do that. Then shut down the computer. Make sure settings is saved though. Put in back the cmos battery and the laptop battery. When you reboot, it should boot up with no password.
