Power problem

    I have an old P2 system. The other day I went to switch it on and the power button did nothing. Upon opening the case one of the Led's was lit up, I tried the on button again to no avail. I didconnected the PSU and reconnected it up and the LED didn't come back on. The system still won't boot. There is no obvious sign of damage and I smelt no smoke or anything. The computer is also only seldomly used. Is this just a power supply feature or could it be something else? Thanks

    first check that the fuse in the plug is intacte. i doubt it is it but try it anyway. What your really going to need to do is to try and get a loan of a psu and through it in and see if it works. Then if it still doesn;t it could be that the motherboard is dead

    Try holding the power switch in for 10 seconds, then letting go
    and pressing it again.

    Check to be certain whether it is an old AT (single row of power pins), or
    ATX (double row of power pins).

    The early ATX motherboards were a bit fanatical about a signal called
    "power bad". They often locked up until reset by either the 10 second shove
    or removing the battery and the power cable from the motherboard.

    PS: Does it have a power switch on the back of the PSU as well as on the PC?

    If it is a ATX power supply the switch will be wired ot the motherboard, on some PC's the actual micro switch can fall into the case so it is not connecting properly.

    The old AT power supplies have the switch wired directly to the power supply and give a definite on/off position when you push them in.

    ** Don't try this if you not sure**

    On ATX motherboard if you look at where the power switch connects to the motherboard you can see the pins that the switch is connetced to. If you remove the connector block and short these two pins with a screwdriver you can power on the PC without the power switch ruling out any problmes there. BUT AGAIN DON'T TRY IT IF YOUR NOT COMFORTABLE DOING IT
