Vista problems with Microsoft ps/2 keyboard inoperative

    I have a ps/2 connected ergonomic keyboard (part number 59758 ) branded as
    Microsoft "Natural Keyboard." It connects and lights up, but the computer
    shows no response to the keyboard. (It works fine with my old 98SE computer.)
    Somewhere along the maze of trying to figure it out, there was a Vista
    message that there was a logitech ps/2 keyboard driver that may be missing or
    corrupted (39). I can find no help on the site. A friend's
    USB keyboard works fine, but I want my ergonomic keyboard back. A few
    other postings show vaguely similar problems with ps/2 keyboards.
    I tried unistalling keyboard drivers, but the only one showing with the
    device manager was the USB keyboard. It uninstalled. I rebooted with the
    USB unplugged and the PS/2 plugged in. The PS/2 keyboard was still
    inoperative. I plugged in the USB keyboard, and it loaded a driver for the

    Is there a solution? I suspect MS did not regression test their software
    against their own older PS/2 keyboard. Good ideas?

  2. humm few things: you sure it's in the right port and not the ps2 mouse port,
    are you sure in the bios nothing is blocking the loading of the ps2
    keyboard, are you sure the keyboard it self isn't defectuous, why do you
    want to use ps2?, usb is much faster and easier to use(most of the time
    99.9% of times). are you sure in the ps2 cable that comes from the keyboard
    that all the pins are there and not bent, or missing. what else......are you
    sure your ps2 keyboard isn't locked(in the older keyboard there was a switch
    that acted as a lock under neat the keyboard.) does your keyboard works
    anywhere else like in bios or in start up. does the numlock light come on
    when you boot?

    I am sure it is the purple keyboard port, though I tried it in the mouse port
    too, just in case something got reverse wired.
    I do not know how to check if the bios would be blocking something.
    The keyboard works in my old 98SE computer just fine.
    I want to use the old keyboard because it is ergonomic, and already
    purchased, and as a small protest against disposing of old plastic when it
    still works.
    The pins are not bent.
    I have not tried it during bootup; what is the key to interupt the boot
    sequence to try that?
    I did not see a num lock light, just the green light next to the number 1 on
    the light panel on the keyboard.
    I suspect a vista problem, and see other ps/2 vista problems in this forum
    that are a bit different but similar regarding keyboard model and symptoms.

    There is no switch to lock the keyboard.

    I tried the thing of interupting the bootup. The computer responds to the
    ps/2 keyboard during bootup; after vista is fully up, there is no reponse.

    I also took the keyboard to another Vista machine, and it worked fine.
    I got a different ps/2 keyboard and tried it on my Vista machine, and it did
    not work on my machine either; whereas it did work on another Vista machine.

    What does the error code 39 driver may be missing or corrupt mean, and
    who/what issues it?

    Hello. I realize this is an old thread, so you probably either solved the problem or don't care anymore. However, I felt I should share my experience since I suffer a similar problem.

    I use a 1986 IBM clicky PS2 keyboard. I can toggle the NumLock, CapsLock, etc when booting up the computer, so I know it still works. Once Vista kicks in though, the keyboard stops working. I assume there's some kind of driver compatibility issue, but it tells me they're all up to date.

    I've discovered that I can get the keyboard to work if I restart my computer. In other words, it doesn't work on the first bootup, but as long as I restart rather than shut down at least once, it will function. It's a bit of an inconvenience, but I love that keyboard so I'd rather put up with that rather than get a new one.

    I've had Vista for over a year and I've still never figured out what causes this problem, but at least there's a work around. I'm thinking of updating to Windows 7 soon, so hopefully that fixes the issue...
