    Hi, everyone. I have a pretty serious problem with my laptop...my keyboard will not respond to anything. (The touch pad and mouse buttons also don't seem to work, though I normally use a wireless mouse.) A USB keyboard works fine when I plug one in, but the built-in keyboard doesn't work at all. I even bought and installed a new keyboard to replace the original, and nothing changed. And it shows up perfectly fine in the Device Manager; it even says "This device is working properly" when it very obviously is not.

    I suppose to start from the beginning, maybe 3 weeks ago or so, my laptop started beeping and spitting out "Keyboard Stuck Key" errors on boot (along with an 8-bit binary value that I don't remember), so I cleaned out the keyboard with some rubbing alcohol and Q-tips, but it didn't help anything. I took the computer over to my brother's house and had him and his roommate look at it, and they noted that there did seem to be a bit of a dent around my "O" key from when I had dropped a heavy external hard drive on it, but that happened over a year ago and I hadn't had any such problems until early-to-mid-November. So I ordered a replacement keyboard and borrowed a USB one in the meantime (meanwhile, the "Keyboard Stuck Key" error was and is still popping up even with the USB keyboard...and, in fact, even when there was no keyboard attached at all), but installing the replacement did absolutely no good; it was still just as unresponsive as before. And clicking "Scan for hardware changes" in Device Manager, under the "Standard PS/2 Keyboard" (the USB one is under "HID Keyboard Device") results in three separate notes of "No driver found". Oh yes, and if it matters, I'm using Windows 7 and a Lenovo.

    tl;dr version:
    - Laptop keyboard not responding to any input.
    - Getting "Keyboard Stuck Key" error message on boot regardless of what keyboards, if any, are plugged in.
    - Device Manager doesn't show anything amiss with it.
    - Replacing the keyboard does not help.

    Could anyone by chance help me fix this?

    Try to disable laptop keyboard from device manager if possible (i doubt it). Then try USB keyboard. If that keyboard stuck key error is still present, problem is on laptop keyboard or it's controller.

    As for another thing, if replacement keyboard didn't help, problem is probably between keyboard and laptops keyboard controller or wiring between them. And that would be hard to fix.

    Possibly that external HDD did damage that took some time to appear.

    Yeah, there is no option to disable it. There is an option to uninstall it, but I don't think that's what I want.

    Will it work with a USB keyboard ?

    Hey, there is another option instead of replacing the whole keyboard, which is replacement of single key. Try http://www.replacementlaptopkeys.com. They offer keys of all brands with reasonable shipping cost.
