    My keyboard stopped working after I got a keyboard failure message during bootup. I have XP Professional and I tried running a diagnostic, reinstallation of drivers & OS, and a USB keyboard. I also kept getting a low system voltage message too. Does anyone know of a fix? Any assistance will be appreciated. Thanks in advance.

    take a real close look at the usb connectors were the keyboard was connected as i think you broke 1 & is causing a short in power to ground with 1 of the usb pins causing low system voltage message.

    My original keyboard had a serial port connection and it registered OK when I did a diagnostic on it and when I tried to repair/reinstall the OS. I also tried the USB ports but nothing happened. The system voltage says F1 to continue, F2 to run setup utlity. Keyboards are unresponsive there.

    is not a serial port but is a ps2 port. try clearing the cmos to see what happens.

    So, I'd hit F2 to access CMOS?

    I had to order a battery since I couldn't find one in store anywhere. I took another look inside at the motherboard and I'm not sure if I looked at the right spot for the jumper. What does it look like and where would it be?

    usually by the battery. is a colored piece of plastic(red, white, green, black or blue) with copper in it. there is usually 3 pins that the jumper is on to of them. check your motherboard manual.

    The replacement battery that I ordered arrived today and I put it in but the keyboard message is still there and a keyboard won't respond. I also saw a white tab with a coil in it but it wouldn't come up and the manual didn't say how to move it.

    what is the make & model# of the computer or motherboard? does the keyboard work on another pc? is the mouse ps2 or usb & can you try another 1 as maybe it is causing the problem, ran into that years ago on a customer's computer.

    It's a Dell Dimension 8300. The keyboards worked on other PCs and one is a brand new Logitech USB keyborad. The original and the mouse are USB. I tried using other ports and other USB slots but nothing works.

    So would that mean that I'd get a new battery or that in addition to something else?
