I have an HP Pavilion 17E that will not boot up. I got it from a guy who said it only needs the PowerJack replaced. Well I replaced it and when I push the power button I get nothing. I have checked the board at several locations and get power but no lights or anything else. At first I wondered if maybe the new jack and cable were bad, but I get power through it. I was thinking even if the CPU was bad I would at least get a fan on.
