If this hits the repair center they would take it apart and check all the connectors, if the cpu can be pulled they would do that, hit the socket with a cleaning spray and put it all back together. Since you doing this would void any warranty and would remove your rights to a free repair my advice is to get it back to them NOW.
PS. "it takes ages to get it ready and I need the computer on a daily basis for my job!" Ever thought of a backup computer?
I have a Laptop Toshiba Satellite M70 SR6, with Intel Pentium 1.86GHz with 2 GB of RAM, 100 MB of Hard drive, with Windows XP SP2 Professional installed. Everything works fine.
Since maybe 2 to 3 months ago I started noticing that most of the times I move the computer without extreme care, being the computer on, it just freezes (no mouse movement, no key input accepted). I have to switch it off lon pressing the power button to re-start, which I believe is not that helpful!
A couple of months ago, while still under warranty it required replacement of motherboard and graphics card. After that job it was OK. But some time after that (sorry I can't precise) it started behaving this funny way.
I believe this must be an hardware problem, maybe a loose hardware connection, but I am not sure. Recently I have upgraded its RAM memory from 1GB to 2 GB but this had no influence on the behavior.
Does anybody has an idea about how I could fix it? I was trying to avoid to take it for repair because usually it takes ages to get it ready and I need the computer on a daily basis for my job!
