  1. Hello all,

    I have this strange problem for few weeks.

    When I start my computer with AC power supply connected, I sometime here after a mintue or two some two beeps, and the computer switches from the AC to the battery, and then again to the AC power after few seconds. Sometimes i can also hear some weak "clicks" in the few seconds the computer is disconnected from the AC power.

    I also had few cases in the recent days, when I turned on the computers, and the screen looks like random noise, and the comptuer did not reacted. I turn it off, then on, and it was OK.

    Three weeks ago, my network card stopped working ok.

    Does it all make any sense?

    The notebooks is IBM R40.
    PC doctors diagnostics on the motherboard, memory passed ok.

    remove the battery and see if the computer runs without problems on the AC adapter. If it does, you are going to need a new battery
