Replaced Top Case Keyboard Mouse Don't Work
I have an early 2008 MacBook where the keyboard & mouse don't function but the power button still works. History is unknown; its owner said that it just stopped working one day. Swapped the upper case with a known good one & exactly the same thing happens - nothing from keyboard & mouse and I'm prompted to search for a Bluetooth mouse every time the computer boots. Have tried booting to a Snow Leopard DVD to see if it's the OS but still no luck. External keyboard & mouse work fine, but obviously this isn't ideal for a portable.
I've had a look at the connector for the upper case on the logic board & it looks good - no signs of spills, so I'm leaning towards a logic board but given the age of the unit I'm hoping that it's something else.
Any guesses as to what could be going on here would be very much appreciated.
