Recently, my keyboard stopped working. I am currently using an on screen keyboard, so sorry if I'm not writing well. I have looked up drivers for my laptop (Dell Inspiron 9300), but nothing seems to help. The only things I can think of in terms of weird behavior is that startup is slower than usual, and system restore doesn't work. I appreciate any help.

Did you reinstall the drivers?

If the drivers haven't helped, then it's most likely (IMO) either a malware infection or a busted keyboard.

Try these free, online scans to see if something has evaded your current protection package:

Does the keyboard work at all? Try opening Notepad and then press each and every one of the keys.
Does the computer recognize that the keyboard is installed? Go to Start...Run...and type in "devmgmt.msc" (without the quotes) and press Enter. Is the keyboard listed there? Does it have any red x's or yellow !'s beside it? Any other issues there?

I checked in device manager, and the keyboard has a yellow exclamation point by it. I checked it's properties and it said "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)" I would do what the troubleshooter recommended (uninstall/reinstall driver), but as it is a laptop keyboard, I don't know any of the information to have it install automatically, and I have no discs. The malware scans returned no results.

I've forgot to mention that I have Linux installed on the system as well, and the keyboard works in Linux.

I would download a new keyboard driver from the Dell website for your laptop. Then I would uninstall the keyboard in Device Manager and install the newly downloaded driver in it's place.

I tried what you recommended, and, unfortunately, it doesn't help. The keyboard still shows up with the "!" by it.

Try a USB or PS2 keyboard in one of the external ports on the laptop. If it works, then it's likely that it's either a keyboard or mobo problem (which gets expensive with a laptop).

Thanks for all your help. I was able to fix the problem by calling Dell Support, and they told me to reinstall Windows. I did that and that appears to have fixed it. Atleast the information I learned here helped me explain the problem to them!

Similar problem here. Keyboard and Pad stopped working. (I use external usb devices now.) Both are shown with a "+" in the device manager. Theyr type is ps2. Reinstalling the drivers returns code 24 (non existing device, not working device or missing drivers). The problem started while I was 10 minutes away from my computer. I could not log on the lock screen any more.

Is there anything simpler than reinstalling windows?
