Laptop freezes and unfreezes when tilted...

Hey guys...

I'm having a very weird issue with my laptop as of two days ago. I notice that sometimes, it just freezes and there is no activity. The CPU (I can hear it processing if it's quiet enough and I put it on High Performance profile), mouse, everything stops working and the screen just stays as it is. When I tilt the laptop at a certain angle (or sometimes place my wrist on the right side of the touchpad), everything comes back to life. I'm pretty sure this isn't a software issue... yesterday I reseated the CPU, RAM, hard drive and WiFi card, but I guess it didn't seem to do the trick. At first I thought maybe there's a faulty power connection, but that doesn't make sense because the computer still has the screen powered on when it 'freezes'

Any other ideas on why this might be happening?

Regards,
Apu

I thought that too, but when I reseated the CPU I cleaned the heatsink and fan and applied new thermal paste as well. I doubt leaning my wrist on the right side of the touchpad remove heat (seeing as how doing that makes it unfreeze) :(

A dry joint? What's a dry joint? xD I've never heard of that kind of piece on a laptop...

Maybe he meant a cold solder joint.
Sometimes they are easy to spot but other times they are not.

Cold solder joint? Hmm... I'll look into that. Is there a way to spot these or do I need special tools?

depends if you have to tap a certain parts of the laptop to get it to work you could look at those areas, and it norm means re-soldiering every joint, you might be better off taking it to a repair shop, unless you are an electronics whiz and can do it yourself :)

I feared that would be the case... I definitely don't have the expertise to do that. I'm gonna have to look around Montreal for a place that could do such a thing >_<

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
