66569 2002-07-29 13:44:00 Hello -

I have passworded the BIOS and now cannot remember the password.

I have to clear the CMOS RAM.

Will removing the CMOS battery achieve this? Yes/No?

What do i do if that isn't the solution?

66570 2002-07-29 21:10:00 In general: yes, resetting the cmos will loose the password. There are some manufacturers that protect passwords against re-setting by cmos battery removal, but luckily only a few. You should have a jumper somewhere that you can move to re-set the memory - removing the battery may require quite a long wait, whereas using the jumper removes the battery power and shorts the supply rail to discharge any residual voltage. wuppo (41)
66571 2002-07-30 05:52:00 If the computer has an ATX power supply, unplug the computer. Just removing the battery will not work if the computer is only "nearly" turned off. If it's an Award BIOS, the master password is well known. Graham L (2)

If this is a BIOS password, you could be in dire trouble.

Laptops cannot usually be reset as simply as a desktop, due to concerns at data security if they are stolen.

Its often only able to be done by a master service agent, and they will (or should) usually want to see proof of ownership.

Also some laptops allow the HDD to be BIOS locked with a password. These are almost impossible to get around.

66575 2005-06-07 00:53:00 you did remove the laptop battery, power lead and bios battery when reseting the bios ? tweak'e (69)
66576 2005-06-07 01:05:00 There is a dos password breaking program called cmospwd.exe, that may or may not work :o A dos boot disk will be required.

It can be downloaded from DriverGuide which this site refers:
www.bios-drivers.com

There is free registration required to be able to use this site.

66577 2005-06-07 01:10:00 But if its a BIOS password on a laptop, you should have no access to the floppy drive untill you reset the password...?

So not sure just how the cmospwd.exe program is going to work in this case Terry?

BIOS protection on laptops is usually quite severe, due to problems with theft and resulting data security. Its usually nothing like desktop BIOS password protection.
