I have a compaq 1247 laptop. I had problems after I took it apart. It was very difficult to get the processor chip back in properly, the little clip has to "snap" in place to hold the chip firmly in the socket. That solved my problem.
Hey Mike
Go back and check the fine cabling that connects LED indicaters to motherborad. There's got to be a small cable you forgot to plug into the board to feed back poer state. Take your time and check everything twice.
