Sony Vaio PCG-K45, Fan No Longer Works.
 

Hi everyone.
Thanks for all your help on a previous issue I had.
Unfortunately, when it rains, it pours...

My laptop fans no longer work, I have dropped my CPU to "degrade" to increase lifetime before the heat causes damage to the computer, but obviously this is only a short-term temporary solution.

I cannot find any information online on how to repair these myself, and the 3 year warranty that I am under (Viking Warranty), has merged or been bought up by Warrantech, and as this computer is the only model I have, I cannot hope to send this away for 2-3 months unless it is the only option.

Does anyone know how to troubleshoot, disassemble, repair or in short, completely save my laptop and its fans?

I run a Sony Vaio PCG-K45 Model with Windows XP Professional, with a Pentium 4 3.06 GHZ processor, 1 GB of RAM, 80 GB Harddrive, with an ATI Radeon IGP-345(?) video card. I noticed the problem about 2 weeks ago, and began preventative measures almost immediately afterwards to save the motherboard/processor.

I believe the only leads I can follow would be a broken circuit, broken fans, too much dust, or another major issue, but am unsure of anyway to begin the repair process. Any help, even if its just to send it away for repairs, would be appreciated.

Thank you, very much.
