A21m shuts down without warning

Discussion in 'IBM Thinkpad' started by Robert W. King, Jul 12, 2005.

  1. Hi folks!

    I've been living with a problem with my ThinkPad A21m (running Windows XP
    Pro SP 2) for some months now. It shuts itself down at random times. The
    shutdown is abrupt - no orderly shut-down with files being closed and so
    forth. Restart is always quite normal. I have had files damaged
    occasionally by improper shutdowns. I've replaced the CMOS battery and the
    RAM. The machine does not appear to be running hot. I haven't been able to
    identify any association with unusual CPU or HD activity. Can anyone offer
    any suggestions as to the cause and cure for my problem?

  2. I have this same problem with an A22m. Most often if occurs
    while playing video, but not always. One way to reduce file
    loss is to disable disk caching. The machine is long out of
    warranty, so I don't really have any hope of repairing it.
    Please post if you find a solution.

    Sounds like it's overheating.

    Does the fan start on BOOT? Clean the fan with compressed air!

    Reseat the RAM, might be memory related.

    Open the unit up and slather a bit (just a bit!) of Arctic Silver between
    the fan and CPU.

    I had this problem with an A21e. Turned out that the CPU fan had stopped
    working, just like James says, so the unit shut down when it overheated.

    IBM wanted to replace the whole mother board (nobody does repairs anymore,
    huh?), but I opened it up and hot-wired the fan to be always on. I got the
    power from an unused USB pad on the main board. Not recommended unless you
    have a fine-tipped soldering iron & you are very experienced with delicate
