So .... i was give n this laptop . I was told everything worked and previous owner is MIA . I was even given BIOS password .
However there is one major problem . I am still locked out from changing settings in BIOS after i log in to BIOS , like to make it bootable from CD .

Does anyone have any ideas how to go about unlocking the damn thing !

Maybe that is why it was free ?:-x

You could try removing the BIOS battery. That should clear the CMOS, and any paswords you would need to get into the BIOS.

I think from what I have read the bios password is locked into its own security chip.You will have to contact IBM itself or if you google the how to there are some tools and equipment that supposedly enable you to access the chip but they arent free. hope this helps......Good Luck....

Ohh, so its one of the locked down models? Should still be do-able, but its much more painful.

Hopefully the password you have is one of the default passwords.....possibly you only have the 'power-on password', not the 'supervisor password'. If you've got some time and a biasic knowledge of electronics, this will lety you break the supervisor password-
