We have just retrieved a IBM laptop from a departed employee who is now out of the country. The laptop is password protected at BIOS level. He is not contactible to obtain this. Is there a way around this?

I will assume it is a Thinkpad.
If you are the registered owner, then you can contact IBM to unlock the bios for you (they will charge for this, as it requires a chip to be replaced)

One way to get around this is to remove the lithium battery for about 5 minutes (just to make sure)...  Often you will have to operate on the computer to get at this battery, so be careful (stay grounded to prevent static shock)...  Once you do this, the BIOS password, which was residing in CMOS, will be gone, and you will not have to enter it at startup...

good luck

There are several methods to go about this:
a)Use manufacturers backdoor password to access the bios:
For IBM bios:
Press both mouse buttons repeatedly during the boot
Or IBM Thinkpad 760 hold down shift+enter when prompted for the password
Other common passwords:
BIOSTAR, biostar, biosstar, CMOS, setup, SETUP

b) Use a password cracking software:

c) Removing CMOS battery for at least 10 minutes
d) Reset CMOS using jumpers


What kind of laptop is this model no?
