    It's a laptop and it's about 6 years old. It still works great but the
    big problem is that at least once a week - without warning - it will
    just shut down abruptly as it's been unplugged with no battery
    installed. The battery is old but it still can will work for up to
    15-20 min on it's own so it's not an external power issue. Anyone have
    any ideas?

    Heat? Lack of ventilation of the CPU, because the vents for the cooling fans
    are clogged? ... Ben Myers

    the vents seem to be working fine. I guess I can set a fan up to blow
    on it and see if that makes a difference, thanks.

  4. It's possible that the thermal compound between the CPU and heatsink has
    dried up, thus creating an overheating issue.
    An older battery trying to charge itself can also create a significant
    heat point, also creating a shutdown issue.

    Time to open the shell and see what you got going on.

    Not the exact model, but it should suffice to troubleshoot your PC.

    Well, I know one thing - I've got a big problem with the AC connection
    to the motherboard. If I move the cord at all the computer will lose
    power and swtich to battery. Could that be a source of overheating?
    Normally I just keep it sitting on my desk and use an external
    keyboard and mouse to control it so it hardly ever moves and uses
    continuous AC power.

    Broken laptop AC power connectors are a plague in the computer industry. Really,
    your best option is to either replace the laptop motherboard (expensive) or find
    a specialist who repairs laptop AC power connectors. HPaq computers are well
    known for this problem... Ben Myers

  7. I use my local TV repair guy for Dc connector repairs. He loves
    soldering that stuff. The adapters are easy enough to find on ebay.
