    I was one of those unfortunate people who bought HP dv2500t with nVidia overheating problem about 2 years ago.:( About 3 months after my 2-year extended warranty expired, my laptop started having problems with the screen that split into 8 parts and showed lines running across. Unfortunately, HP was of no help since my laptop wasn't on the list of those recalled and asked me to pay an extra $400 to get it repaired.

    After doing research on the net, including this site, about this problem, I decided to replace the motherboard myself. I ordered an exactly the same motherboard that came with the same nVidia chip from a reputable seller who specialized in selling used motherboards. He assured me that it was tested and even recommended adding a piece of copper on top of nVidia chip. So I carefully took apart the laptop, added a piece of copper that came with the new MB using instructions posted on this forum (with Arctic silver 5) and reassembled it.

    To my surprise, the laptop wouldn't power up. When I plugged the charger, the blue LED light would go on both the front side and the right side where the charger goes. And then there were no other signs of life from the laptop. I thought maybe I didn't connect some wires properly. So I disassembled and reassembled the laptop 2 more times. All to no avail.

    I can't for the life of me figure out how to diagnose where the problem is now. Everything, except for the video was working before. Now, I can't even power it up.:eek:

    Any help would be greatly appreciated.
    Thanks.

    What makes you so sure? Is it possible that there is a poor connection somewhere or a short-circuit?

    well you said you double checked all connections and still nothing..replacing a motherboard is straight forward by just connecting all the cable. Thats why I think you probably got a bad motherboard. Try putting back the old motherboard to see if it turns on.. if it does then that will give you enough evidence that the new motherboard is bad. But if it doesnt then one of your power cables is shortout or broken..

    I forgot to mention that I had to replace one power cord - the one that connects the power button to the mb. I ripped the old one while taking the laptop apart the first time. Is there a way to test that cord to see if it's damaged inside? Because on the outside it looked fine.

    P.S. Putting back the old mb is not an option. I played around with it after I took it out. It's probably been damaged by static electiricity. Besides, I pulled out some things from it.

    If you don't mind me asking, where did you get it from and for how much? Thanks.

    If you are talking about MB, I got it from eBay for about $150. The guy I bought it from must have sold hundreds of them, mostly from HP.

    I see you have the laptop with almost the same configuration as mine. I even did the copper mod, but wasn't able to bring it back to life.

    You have either a bad cable or a bad power button. Try touching the Quickplay button and see if it powers up.

    My laptop doesn't respond to any buttons pushed whatsoever. Yesterday, I plugged it into the power outlet through the "Kill A Watt" device. Although the blue LED lights were on, it wasn't drawing any power from the outlet because "Kill A Watt" showed zeros.

    I am taking part of it back. When I connected the laptop through the AC adapter, "Kill A Watt" registered 35W. Then, I took the battery out, wattage dropped to 0, which means the battery was charging. The problem has to be somewhere inside.
