A long post, I know, but I wanted to get all the details in. My brother sent me his zv5000 laptop to try and repair the power connector. He said that it wouldn't charge the battery and that he would have to move the plug around to get power. After doing some research, it seemed like a bad power jack, which is a very common problem with HP's. So I took the laptop apart and checked out the connector; it seemed fine. When I put it all back together, it wouldn't boot. My brother said that it worked before he sent it too me and I forgot to try it when I got it. The power LED and all the lights on the keyboard would turn on, the processor fans ran for about 3 seconds, then shut off, and there was no display or HDD activity. I figured, the motherboard probably died, which I was going to replace anyway. After getting a used one from Ebay, I put it in the laptop and it did the same thing. So, I grabbed a different processor and tried that. No luck. I have gone so far as to take the board completely out of the laptop and with just power and the display hooked up, no RAM, no HDD, no keyboard, and tried to boot. Nothing. I have also tried using an external monitor, with no luck there. The only things that have been common are the processor fans/heatsink and the power supply. The power supply voltage checks out ok, about 18.5Vdc. I am really at a loss as to what it could be. Is there some reset on the board that I am missing? I really don't want to put any more money into this thing. My brother doesn't really want it back, but I want to try to figure it out anyway. Any help would be appreciated.
