System boots to the Thinkpad screen giving options F1 for Bios or F12 temporary boot device. Neither work. Any ideas - please regards pat

A 2628 is not a Thinkpad model, can you look around and find it? 2628 MAY be part or all of the type number. Sounds like you have a dead bios/cmos/backup battery If you post "the numbers" for your Thinkpad, I can probably point you to the spot on the IBM support site where you can download the "hardware maintenance manual" and lean how to change it. Is it dispaying an error number, and what exactly does the screen say? Almost sounds like it's searching for a legitimat bootable device, as in, something wrong with the hard drive. Did it work earlier, or did you just buy it?

The numbers, 2628, do mean something. That computer is a Thinkpad A22M and here is a link to IBM. Good Luck Smitty

Sorry, forgot the IBM link http://www-1.ibm.com/support/search.wss?q=2628&rs=0&lang=en+en&loc=en-US&from=tss&ics=iso-8859-1&cs=utf-8&cc=us&search.x=46&search.y=8

Well I didn't say they didn't MEAN ANYTHING, I merely indicated that was not the model no. The way the IBM support site is structered, you need this number first. Also, even though related, the IBM site also shows (at least) that this could also be an A20 or A21 series I just don't feel like cross referencing every single possible type number, to every single possible model number, with all the possible type number suffixes
