HP G62 Overheating

[lagouzas]

Hello everybody, I need your lights and exepience to gain some time.
Laptop is HP G62 with an I3 processor and a switchable AMD Radeon GPU.
Laptop appears a heavy load of RAM use and it's powering down. When powered on, BIOS shows that system was put in hybernation due to overheating.
My actions:
- I Cleaned the fan from inside, put new thermal grease compound. (it really gives a blast of cool air now.)
- I tried new ram module and a used I3 working processor with no effect.

Laptop cannot complete the format process in windows 7. It always crashes and shows the annoying message.
I am thinking of the following actions:
-Modify the fan in order to continuously work. (I don't think that it is needed, but I don't know what else to do.
- Reball the GPU bga chip. (my customer used to be a heavy gamer.)
- Reball the northbridge bga chip.

Any suggestions from someone willing to help would be appreciated.

Cooling seems to suck like the Athlon II HP Compaq laptops.

before you go deeper, try another processor with the same bus speed.

Check hard drive if the health is ok, othewise if the HDD bad, you can not able to install OS.

HDD has no bad sector, and processor change had no luck.

Re: HP G62 Overheating

if you got good voltage runnin on coils, caps and 8 legs ic around cpu, the problem might be cpu socket, you can reflow it, use liquid flux. make sure you have good upper/lower heater, otherwise the socket will become uneven after reflow.

Re: HP G62 Overheating

If anyone can be helped from that, the problem of the laptop was a faulty heatsink. The fluid or gas, or whatever has inside was absent, so it couldn't freeze the system. No obvious hole on the heatsink... Sometimes things may be simpler than we believe.
