Cmos checksum error

  1. Hi,

    I saw this messageboard when I was researching some tips regarding CMOS Checksum errror. I would like to have some advise regarding this error message: CMOS checksum error- Defaults loaded Warning! CPU or CPU ratio has been changed. Please re-enter CPU settings in the Set-up!

    Is this an indication of a failing CMOS battery? I opened the CPU, got the CMOS specs SONY CR2032 3V. Should I go ahead in replacing this? Another thing, if replacement is the next step, is MAXELL CR2032 3v ok, even if the brand is not the same?

    Hoping to read your advise soon. :blush:

    Thank You,

    Hello and welcome to Techspot.

    It my well be your cmos battery that needs replacing.

    Any CR2032 battery should be ok.
