I bought an HP pavillion dv6000 about a year and a half ago. The other day It was on internet was up and i wasn't actively using it when it just shut off. I was like ok? So I pressed the power button to turn it back on and it wont turn back on. all the buttons light up like normal but not even half a second after that it just all turns back off. The charger is plugged in and lit up same with the battery light and it would flash if it was low on battery which it doesn't. Ive tried taking battery out and all the other things Ive read online but nothing works what could be the issue?
I'm already fed up with HP and will never buy a laptop from them again, they should stick with printers.

Sounds very much like either the Graphics chip or Northbridge chip has become detached from the motherboard. This is a very common fault with these laptops. Both these chips are whats known as "Flip Chips" and are attached to the motherboard using Ball Grid Array (BGA). This means the chips are attached to the motherboard using hundreds of balls of lead free solder, in this case 0.6mm. Because these laptops have poor cooling, thermal stress causes the balls to crack or become detached from the motherboard. Its likely that after 18months of use the fan has become blocked which has added to the overheating. Its possible to get the motherboard repaired by removing the chip and replacing the solder balls (reballing). This needs specialised equipment. Avoid anyone who is just heating up the chips (reflowing) as this can repair it, but its generally wont last more than a few months if your lucky. Also reflows are often done by using hot air guns or paint strippers. These can cause more damage than they fix.

Its also worth noting that the Nvidia graphics chips being a flip chip uses BGA internally to attach the top part of the chip to the bottom part of the chip which is then covered in resin. These are a common fault, and cannot be replaced. A professional reflow may work. But the results are mixed.

To get the chip reballed your looking at about £55 - £65, and many use lead solder which is more reliable long term. Look for someone using Dark infra red technology for the reflow/reballing.

Hope that helps.
