Question

I need help with this black screened laptop

by aimlesssidekick / January 30, 2013 7:13 AM PST

I have a HP Pavillion DV6Z "entertainment laptop" that I ended up getting from my girlfriends sister for $50, she said she could never get it to work right, the screen wouldn't even come on. After a few updates, I eventually got the screen to turn on, however it still seems to have problems. Every so often when I turn it off for updates the computer's screen won't come up, however it will appear on an external monitor. And I have to hard reset it a few times for the screen to come up.
Sometimes it still goes black, especially when trying to play a game. For example: I start of KOTOR and I can make my character, then once the game actually starts, and it's playing a small cinematic (I click through the scroll) it may play for a second and then the screen is go black and the sound will stop. The computer will normally show up on an external monitor (when it goes black), but it won't when it goes black.

I have tried everything I know, and it doesn't seem to have helped, so I turn to you. I am willing to upgrade the computer (in fact I am about to upgrade the ram to 8gb and possibly the HDD to a terabyte).

If I'm not mistaken

If I'm not mistaken, this is a rather well documented issue with that model. If memory serves, the heatsink on the GPU has a tendency to go on a bit of a walkabout. You're probably never going to fix this issue on your own.

Sooo

Would you suggest that I take it to a professional?

The "professionals" at your usual service counters do not do more than swap boards. They have to do that since any quick fix such as putting the heat sink back on can never be covered by any warranty.

Given the rather low investment why wouldn't you dive in and see if the heatsink took a walk?

Over in the CNET Laptop Troubleshooting forum at the top we have bonus material about opening up the laptops and more. I've sure there is a YouTube video on this laptop too. I never wrote to replace a thing. I do agree it's a good idea to see if the heat sink went for a walk.

Is there a way to see if I need to replace anything?

How will I be able to tell if that's the case? The link was to a new thermal module heatsink.

I've yet to replace that part.

I've only had to wipe off the old compound, put on some fresh then button it back down. This part if it failed would tell me the machine had been put through a meat press.

Glue?

In reply to: Oh wow

I only know of a few instances I would elect to use glue. I use thermal compound. It's not glue.
