  1. Hello all,

    I'm hoping someone can give me some advice for next steps to get my keyboard working.

    I've read a few posts here and everywhere on the web but so far I've had no success.

    Here's the symptoms:

    -keyboard works in bios, windows recovery/setup, at the boot menu prompt etc.. but upon loading windows the keyboard is completely unresponsive at the logon screen

    I've tried:

    -a different keyboard
    -unplugging everything but monitor and keyboard
    -checking BIOS settings (nothing that refers to mouse) -tried turning off USB controller, there is a setting for the ps/2 port, it just says auto and then upon selecting it shows the irq setting which is not changable
    -booting in safe mode (still cant logon when prompted)
    -remote desktop not running so I can't logon that way
    -full windows repair
    -FIXMBR - repaired master boot record
    -ran CHKDSK /r from recovery console - it reported it found and fixed some errors on the disk

    Other details: ps/2 keyboard, usb mouse, xp home, was sp3 but now after repair its sp1

    I'm still left with an unresponsive keyboard at logon. It's so frustrating! The only thing I can think to try left is a USB keyboard, but I fear that won't fix it. I'm hoping there is a magic file i can copy from the xp cd into the system that has become corrupt.

    Any help very much appreciated.

    I would try a USB keyboard. When you use a USB keyboard for the 1st time and you get to the login in screen it will not respond right away, windows needs to load the driver for the USB keyboard which takes a little while, so dont be impatient (you will see an hour glass at this point). If you do use a USB keyboard make sure to enable legacy support in the BIOS.

    kb error

    Thanks for the reply gguerra. I agree, getting a usb kb is pretty much the best bet at this point. What's odd is I have tried two different ps/2 keyboards and they both work fine before loading windows. Which leads me to believe that windows is loading a bad driver or something. I've read that the bios hands over control of the keyboard and mouse to windows upon loading. I believe something at that point is occurring. It must be pretty 'low level' system file to not be repaired with a windows repair install. I checked the bootlog, there's a lot of that 'did not load driver ...' but thats apparently normal. I looked for any attempts to load with error messages but there appeared to be none. I did however see this file loaded multiple times 'i8042prt.sys'.

    Cheers and thanks again for the input.
