BleepingComputer.com: HP Pavillion DV6000 - Won't post/continual reboot

Hi, I have an HP Pavillion DV6000 laptop. It will turn on (lights come on) but the screen remains black and it won't post. It does make some kind of sound but it doesn't really sound like the fan. It will stay powered up for 10-15 seconds and then reboot itself, and continue this cycle forever if I let it. Before it finally "died" I was having problems with the wireless network dropping a few times every night.

This laptop has already been sent into HP once, a few years ago, for basically the same problem, but it isn't under warranty anymore. I've done research online, trying to figure out the problem and possibly a solution, and I'm thinking it's the Nvidia chip. Does that sound right? Does it sound like I need to reflow the Nvidia chip? Or get a whole new motherboard? And if I need to reflow, does anybody know of a good manual or video I can follow to do it myself? Thanks!!

Hello and welcome to Bleepingcomputer.

Do you remember what was repaired when HP repaired it the last time?

The process of re-flowing is performed by placing the video card into an oven after it is pre-heated to 350 Degrees F.

The video card has to be stripped of any plastic parts that might melt. (If possible.)

The card has to be in the open for 10 minutes, then the oven is turned off and the card is left as it is, moving it may cause the liquefied molten solder to spill over causing solder bridges, which is not what you want.

Open the oven door and wait 30 minutes before attempting to touch or move the card.

Put back any plastic parts and re-try the card.

You may have to repeat the process a second time, if the first time fails.

More experienced electronically inclined people can repair solder connections by carefully using a low powered 15 watt grounded soldering pencil and a keen eye and steady hand under magification.

If that fails, the card has a defective component.

Bruce.
