unexpected power interruption

[amuntaner]

Hello friends,

I have a PCG-K315B model and recently I have sudden power cut offs. It is unpredictable it happens in any moment even after few minutes working on. It seems like the computer forces power disconnection. I don't now if a clue could be that it heats up more than normal and a high and persistent fan noise.

Is anybody sufferig the same problem? Any solution?

Thanks

Hi amuntaner,

Welcome to Club Vaio,

It could be that your vaio is overheating, could you download and run Mobilemeter and post back the temperatures..

[amuntaner]

Thanks friend. I will do and revert asap.

I run mobilemeter and temperature is growing beyond 87ºC after a few minutes working with no special program, just internet browser.
And HDD temperature is moving around 45ºC.
Is that too hot? what is the normal temperature for a mobile like mine (Sony Vaio PCG-K315B, with intel celeron D 2.93gHz proccesor)?

Hi amuntaner and welcome.

That is far too hot and is almost certainly causing your problem. Your CPU should work at 55 to 60 degrees under light loads.

You need to clean out the air vents to your processor - even a small amount of dust can cause problems. Try a can of compressed air from a distance of 10 cm and see if you can expell some dust.

If this does not work, you may have to take your Vaio apart ............

Yes, it's auto-cutoff due to overheating.

Follow the steps laid out by Blencogo

thanks again friend. Do you recommend me to open the laptop and clean inside, or it is too dangerous? In first case I would appreciate any guideline how to open it and access inside.

It would be a good idea, but I don't have any guides on that

[amuntaner]

Thanks for your hint, but could you know how to dissasemble the computer and having a clear access inside?. This way I will be sure if there is anything else damaged.
(my model is PCG-K315B)
