Hey. My dad turned on the computer today to find that the keyboard was unresponsive. There was no keyboard detected through the Control Panel. The only thing I have about this so far is that when I unplug the keyboard and plug it back in, all three lights (NumLock, CapsLock and ScrollLock) light up before shutting off. Then, the hardware is still not detected. I'm not good with computers, but I believe if the keyboard has a driver, it should be an HID (Human Interface Device). I did notice that one of the HID's in the Device Manager has no driver. Is it a driver problem or could it be from something else? Thanks.
