    the time in XP on my my dads Acer Aspire SA-80 keeps displaying wrong time now and again - ive just re-installed XP for him as it was corrupt and updates wouldnt install

    we have a new battery for the mobo - is it safe to just swap the battery?

    im worried the CMOS will clear and this will completely ruin the motherboard

    as you can tell ive never changed a battery before - the computer is only two years old and he's had this problem for most of this time

    It is safe just to swap it, I'd prefer turning the power off before doing it ;) CMOS won't propably clear within the couple of tens of seconds it takes at most, and even if it would clear, you'd just need to set the settings back.

    Turn computer off
    After computer shuts completely off, unplu power cord.
    Push Power/On button to discharge remaining power on mobo
    Either use anti-static wristband or place hand on computer box (metal)
    Remove battery and replace with new one
    Replace side cover
    Plug power cord back in
    Start computer
    Press Delete or whatever for your model computer and enter the BIOS
    Check settings, adjust if needed
    Save settings and proceed with startup
    Set clock and date
