VGN-FS285H getting very hot

[Tiggerssprings]

Hi, ever since I got my laptop it keeps getting so hot underneath that I cannot put it on my knees because it starts to burn me, anyone got any ideas.

Thank you

Hi tiggerssprings,

what is the normal running temperature of your vaio..?

If your unsure, mobilemeter is a handy application to use..

Have just downloaded that program it says crit temp is 105 and passive cooling is 95 and the graph say temp is 84 degrees celius and hdd is 48 is this anything to be concerned about.

Thank you

Hi tiggerssprings

Those temperatures are high, try clearing the cooling vents of dust with compressed air (you should be able to get this from your local PC shop), holding the can upright give the vents a short blast from a distance of approx. 10cm if you hold the can to close you could damage the fan..

If you do not notice any improvement then your vaio may need to be disassembled in order to deep clean the fan and cooling vents..

I had this problem with my FS-315s - the problem was fixed when I changed the option in the VAIO power management tab of windows xp power settings to 'adaptive' instead of performance. I havent noticed and speed difference, its just been cooler and quieter.

Yes, setting CPU control to adaptive is better than performance. When set to performance, the CPU is always running at full speed, so even when idle, it's going to get hot. If you set it to adaptive, it will run at about 800MHz until you do something, e.g. open an application, then will run at full speed to complete the task, before dropping back down again. Therefore, you notice virtually no difference is speed.

You may also want to consider cleaning the heatsink with some compressed air and/or putting so decent thermal paste on the CPU (if you're the daring type). Check out http://www.sebby.me.uk/vaio/ and you'll see about half way down the page that I show how to do it.

Brilliant, will help my little fellers march further.

Did you know, male laptop users who use their laptops on their laps have reduced sperm motility and general vitality! :smileyhypnotized:

Jumpsuit you are a lifesaver!

Thank you all have changed the cpu power settings let hope it works.
