I rebuilding a used IBM 760ed Thinkpad and cannot seem to find where the cmos battery is located. Stripped down the case all in vain , are the cmos batteries located in the LCD lid? I got it to boot up however it asks for a password. Any input wouldbe appreciated.

I believe that the Thinkpads, and many other notebooks, use non-volitile RAM (EEPROM or EAPROM) to store the data that is stored in CMOS memory on a desktop system.

On IBMs in particular, the Password is part of anti-theft security.
The ONLY wayto reset the password is to take the laptop (along with proof of ownership) to an authorized IBM repair center.
They have a special utility that they can run to reset the password for you.

Laptops differ from desktops due to useing a small part of the hard drive as a suspend. A few also use the cly 0 head 0 sect 0 as a place to store the custom bios settings. If you have the original software that came with it, check to see if it hasa setup program. That should overwrite the the custom setting and get back into it. If you low format the disk be sure to leave unpartitioned space for the sleep mode.
Also check IBM's websight and FAQ page for bios updates and patches.
Good luck!
