My kids have an Aspire 4330. A couple keys were broken and some chocolate had been spilled underneath where the cpu fan resides. (it was still functioning ok) I took it apart and cleaned it, put it back together and the keyboard would not work. Everything else worked fine. I ordered new keyboard and installed it, still would not work. Figured I damaged the clips on the board that held the keyboard down, so I ordered a new motherboard. Installed it, it came on but still no keyboard. I rechecked all my connections and even went so far as to order another new keyboard. That keyboard would not work as well. I am sitting here looking at it wondering why everything works on it but the keyboard. If i plug in a usb keyboard, it works just fine.
What gives?
