I pulled this little unit out of retirement but it needs a new CMOS battery; what is the correct part number or battery type for a replacement? Thanks!

  • Why do you need to replace the rtc battery? Are bios settings being reset?

    Yes, at every reboot it complains of a CMOS checksum error and the date is reset. I just assumed the battery would need to be replaced as a result. Is there something else I should try? This unit was sitting on the shelf for many years...

    CR2032 is usually the battery for most - if not all - computers. A good quality battery will normally last about 4 years, but less if the PC spends most of its time switched off.

    Some devices have a rechargeable CMOS battery which gets topped-up from the mains power and these will last much longer.
  • Have you just tried to unplug and reconnect the rtc battery (the one in battery format with a yellow plastic)?

    Yes, it's a CR2032, but with the wires already soldered on. Check on yours first to see if it has a two pin connector, or a three pin with just two wires. They are easily available on Amazon and eBay. It's likely held in place with a little blob of adhesive and you can do the same thing with the replacement.

    The Acer manual shows it here @billsey:

    That one looks to me like the three pin with the outer two pins populated. Most of them on Amazon or eBay have just a two pin connector. Last time I replaced one on a notebook I had to pull the pins from one and put them into the other. :(
