Diffirent HP DV6000 Problems.. Somone has ficed this

I have a HP DV6000 Laptop. Im aware of the problems these models have. But this one I have not yet heard of. When I attempt to power it on, the lights turn on for 2 seconds, and it shuts right off. Its not like the Video card issue everyone speaks of. I have extensive technical background, and I have tried taking everything out, and trying each part one by one. I have tried swapping the power button ribbons, I have tried removing the bios battery. I guess im wondering if anyone else has ever been able to figure out whats going wrong with this setup? copuld it be a lack of contact between heat sync and CPU? please give me whatever input you can. I would like to not have to spring for a new Mobo. I can solder, and I am thinking of trying to heat the soldering points with a heat gun maybe. I dont know if thats the problem tho. Thanks!!!

Oh, and also, when the AC adaptor is plugged in, the blue LED surrounding it is on.

I also tried all this (of course)

1. Remove battery.
2. Remove AC power.
3. Remove and reseat your RAM modules.
4. Replace your RAM modules.
5. Hold down your power button for 1 minute.
6. Replace your AC power (not battery) and turn on
remove the small bios cmos battery for 15min and then put it back in


Need some guidance from someone who has dealt with this in these models.

 

after about a week of the graphics problem (while i was waiting for hp to send me the box), my dv9543cl started doing this too, so i think you're gonna need a total motherboard replacement

 

Defective NVIDIA chips can present a wide variety of problems. especially if it's the NVIDIA northbridge chip in AMD CPU notebooks. Then there are the uncommon problems, like a power regulating chip burning up. Anyhow, v3loc1ty's right, it sounds like a broken motherboard. You can try reflowing the NVIDIA chip using LordWalrus's instructions here:

(Read the rest of that thread for a pointer to the surprisingly effective copper penny trick.)
But inspect the motherboard for burnt chips too, just in case.

 

Thakns for the response.. I took your advice and decided I had nothing left to loose with the motherboard, and took a hairdryer to it for about 20 minutes to try and re-condition the solder on the board. I added more thermal paste to the CPU, and did the penny trick with the GPU, and surprisingly enough, IT WORKED. thing started right up. it killed the mini-PCIe slot tho, cause now the wifi card does not work. Tried a diffirent wifi card, and that dosent work either. Oh well. Right now, im using a USB wifi adaptor, and im gonna invest in one of the mini pcmcia ones for the slot on thefront. Thanks again for all the advice. Saved alot of money. Lets see how long it lasts now.

 

Failed WiFi is a NVIDIA chipset failure symptom, so you only partially fixed it. Try again with a heat gun? More heat, less air than a hair dryer. You did prove that this is the solution though.
