Someone had spilled on this keyboard in the past, and the lights on the right side of the keyboard stopped working. The left side would flicker on and off if the center of the keyboard was pressed. After removing the keyboard and completely disassembling it, it was then reassembled but now the backlight doesn't work whatsoever. I have no OS installed, and no hard drive, so there are no settings to play with. Right now its just booting up to the white screen with a ? file folder. I bought a new keyboard from ebay, and I thought that would solve my backlight problem, but its still not coming on. Any ideas?
