You will have to remember it. IBM puts a security chip on the motherboard, the bios password is burned into this, and there is no way around it. There are a few places that will replace the chip, but they are very expensive. The only other way is to replace the motherboard. I've found that replacing the motherboard is cheaper than having the chip replaced, so, if possible, remember the password.

These laptops usually have a switch that is activated when the cover is opened and thus the message. Would suggest talking to IBM support for a master password, that will help you thru and get the same cleared.

you should try to dopen it up, locate the cmos battery, plug it out for about 30 minutes and put it back then test if bios has been cleared. if not, try to google and find out backdoor bios passwords for your model. hope this helps.

Bios pass word

You can clear bios with factory defaults reset.
For that open back cover of your laptop.

Then put again cmos cell in it's position then it not ask password.
Let me know if you need more assistanse.

My ibm thinkpad r40e is asking for CMOS password what to do

You will have to enter the bios and reset the date and time, but you might need a new cmos battery.

Re the cmos password, you should remove it, but will have to know what it is. This can also be done while you are in the bios.
