Help!

My daughter's HP Pavilion dv 6700 was over heating so I tore it apart and removed enough wool out of

the CPU fan to cover a mouse... But once I put it all back together the video does not work.

It worked just fine before I took it apart and have torn it back down a couple of times and put back together with no luck...

Is there something that I may have done that messed up the video on it?

She heads back to college in a few hours and needs her laptop and I feel terrible about it,

Any suggestions?

thanks

OK, I got it working... the video chip is a BGA type (Ball Grid Array) and after some researching, I found that the

HP laptops are notorious for these parts getting hot and creating intermittent connections to the motherboard.

I took a thin piece of cardboard and cut out a square in it the size of the video chip and then covered the cardboard with

aluminum foil and  made an opening in  the foil where the cut out was.

I placed this over the motherboard to act as a heat shield with the video chip exposed. I then took a hot air gun

(for stripping paint) and heated the part up for a minute by circling the part  while not applying too close or direct heat on it.

This allowed the part to reseat to the motherboard.

I reassembled the laptop and it booted up fine.

Case solved

This is a very easy repair. The laptops graphics card needs a reflow. We are cakled Ninatec laptop repairs and are based in Canary wharf in London. If you are not in London just call some laptop repair companies and ask for infra red reflows. If they do not have an infra red reflow machine find a companiy that does. ,!!

Either its FM or holding down the F4 key worked. Thanks.

Where did you come up with this fix?
