HP Pavillon DV6000

[dondrusco]

Model dv6152eu

It won't start at the first four-five attempts.
Then start, but no HDD detected.
After 5 minutes in boot menu, it starts working correctly.

I checked voltage 5V @ HDD - there was only 2,7V
5V @USB was OK.

I replaced capacitor 100uF/6V - now it starts with no problem!
(I had to use 200 uF/6V - I was not able to buy 100uF for adequate price.)

Was this cap obviously damaged or did you have to test it?

Why I ask is its an unusual cap to blow.

Congrats on a successful repair!

Re: HP Pavillon DV6000

Just as a warning, the HP DV**** series notebooks have a serious video problem. The basic is the video chip that is soldered to the mobo doesn't quite touch the Heatsink... typically what happens is it gets so hot, it desolderes some of the BGA points. I have worked on many DV2k, DV6k, and DV9k notebooks that all get this problem.

There is a trick you can try: http://www.youtube.com/watch?v=bnkQNmKauEc

I have seen people use a 200watt bulb to reflow the chip. And if you don't have copper around to make a shim, you can always use a penny, but a copper shim would be MUCH better for heat transfer, unless you surfaced the penny flat.

A buddy of mine got a DV2000 with the same problem, but was able to get a updated board directly from HP for around $150. The newer revision board come with a thicker heat spreader on the video chip, so it makes contact better with the heatsink..


Hope this helps.

Re: HP Pavillon DV6000

I have tried this trick (hot flux) - it worked for three months only.
Then I sent board for repair into non-authorized HP service, focused on BGA chips repair/reball. They gave me 6-months warranty on repaired board.
They have used +5V from USB as source for fan - no fan control from BIOS.
It is loud, but chipset temperature is pretty cool ~60 °C
