I have a HP DV7T-4100 laptop with a windows 7 64-bit OS.

I did already have a working keyboard, but 2 buttons were missing, so i just replaced it with a new keyboard of the same make and model compatibility. I installed it with the ZIF socket, and it doesn't work at all. My Windows 7 device manager however recognizes it and drivers and such all seem to be in good order. Not sure if this is relevant, but the I/O range is 0060-0060 and 0064-0064. IRQ is 0x00000001 (01), and there appears to be no conflicts.

I installed my old keyboard back to see if it works, and it works perfectly fine. I've switched back and forth trying different things for the past 3 hours, and i'm all out of ideas.

Any help would be greatly appreciated.

Do you think it's a simple case of a defective replacement keyboard?
