    I am trying to assist a new teacher at my wife's school set up school computer.

    Apparently there is no power to the keyboard.

    After system boot, when the keyboard is unplugged and plugged into the back of the computer, the Num Lock, Caps Lock, and Scroll lock lights flash once and then go off. The same thing happens with a different keyboard. There is no response to keyboard input after the system boots (it gets to the "Press Control Alt Delete" point but nothing happens after that. There is no place that wiggling the keyboard plug will keep the lights on.

    During the boot process, the lights do not flash.

    Tapping F8 during boot does nothing.

    Using Windows XP Pro, SP2

    Keyboard uses a standard connector and the mouse uses a USB connector. Mouse works OK.

    Need to get this computer running. Thanks.

    Can you try a USB keyboard? It may not work until Windows is running though.
    It could be that the Keyboard PS/2 port has been turned off in the BIOS. Try removing the Motherboard battery for about 15-20 minutes to reset the board.

    I don't have a USB keyboard available. Will try the motherboard battery removal tomorrow. What else may reset besides the keyboard selection? I'd rather not reconfigure the entire computer...any problems to look out for?

    Resetting the BIOS will put it back to the original configuration as when new. Someone may or may not have changed other things such as settings for onboard video or AGP video.
    I'm thinking that if the PS/2 port is turned off in the BIOS, then maybe the USB keyboard support is turned on. A trip to wallyworld with a ten dollar bill will get you a USB keyboard. It may be worth the try.

    I tried two keyboards with the same result, no power to the keyboard and the blink when the cable was plugged in. The solution was a THIRD keyboard that worked perfectly. I'm still not convinced a gremlin doesn't live inside the computer! Marking the thread solved.
