Hi Folks

Where is the CMOS battery located on a IBM ThinkPad 600. Also is it a regular CR2032 Lithium battery? If not, where can I find one?

    Accepted Solution

    You are not going to like the answer; it's built into the RTC/CMOS RAM module. I had a similar situation with an early Pentium Shuttle MB, but it's still working, so I'm not too annoyed. If it's failing, you can check with IBM for a solution, or just keep the battery pack charged up.

    For further information go to The IBM site is very easy to navigate. I found this by the 4th screen!

    well i now sure if it is correct, but on some laptops CMOS battery actually separate so just talk it apart and you should see it on the mother board. And if it there you should be able to by it from batteries stores....

    P.S. by the way talking laptops apart are so much fun and pain....
