Sony Vaio PCG-K45, Fan No Longer Works.

[MPelham]

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.

Have you tried VAIO update yet? I've had my PCG-K45 for 7 years and have never had a problem with it. Make sure that you're not using programs that are meant for Windows Vista. Windows XP and Windows Vista Have a lot of compatibility problems. Thank God for Windows 7. I still have Windows XP on my main computer, and as long as I keep it updated, I don't have any problems with it. There is a free program you can download called ccleaner. Just enter that into a search engine and that will take you to the parent company website : www.piriform.com. You can enter that too. They have several different software programs that you can download for free to clean up your computer. These programs include C drive cleaning, Registry cleaning, and performance monitoring. These programs are 100% free. You can donate if you want to but you don't have to. I heard about these programs on the Kim Komando show and they are everything she said they were. Hope this helps. If it doesn't, then I'm afraid you may need some technical assistance. Hope it works for you though. Take care, and let me know if it doesn't work.
