    ECS KM400-M, good caps yet both are dead

    Hi,

    I've got two ECS KM-400M motherboards. One I got in a lot of motherboards, the other one comes from an Acer Aspire T120 I found in the dumb last week.
    Neither of them work, yet most of their caps are Panasonic.

    The one from the Acer will turn on, fan spins for a couple seconds and there's a weird low pitched beep.

    The other one will turn on, fan spins for a couple seconds and then stops.


    I've tried them with different RAM sticks, Palomino and Thoroughbred CPUs (the one from the Acer came with a XP 3000+ yay ! ). I've even tried them without their BIOS chips but it's still the same.

    Any ideas ?

    Check the BIOS battery, if less than 3 volts, replace it.

    You should get a PCI BIOS code card. It will give you 2-character codes you can google.
