My laptop is VGN-CS17G .
It automatically shuts down as soon as i switch it on. I am not able to view its first screen.
It just shows the safe mode option screen.

Can you get into safe mode at all?

If you can then please Read this:

and post it here:

if you can't get into Safe mode or Normal Windows, your PC maybe overheating.

This can happen with two things.

The Battery has gone bad and is sending more volts than is supposed to. Solution Change/Repair Battery or you could DIY:

The Other Problem could be your Fan is clogged with Dust and Hair and what not, You can try and clean it from the Side Vents or you can open it up and free the Fan.

Before you open the Laptop try and see is it overheating, and try and hear if the fan is spinning.

Let me know what you find.

Regards :)

can any one guide me how to open the back of my viao VGN-CS17G to clean the fan as opening up a viao is pretty difficult and it is better to be sure of the steps before hand. thanks a lott in advance for the help and the advice.

Fist of all, is your laptop getting hot, can you hear the fan? Did you try to clean it from the vents?

If is it heating up try and Use a Vacuum cleaner or goto any computer or hardware store and a compressed Air Duster. You may find good results if you combine both.

If you don't notice any difference it may not be the fan. if you still wish to venture on and open up our laptop, understand it will be at your own risk.

Please look at this:

You fill find the fan on the second step, you are lucky the fan is accessible without too much work.

yes it worked as i successfully opened my laptop and cleaned my fan.
on opening i found that the fan was pretty hard to move but i was not able to find any sort of dust. i sprayed phillips dust remover and tried to rotate it by my hand. after some time i found it to be looser and it was moving much easily. well the temp is stable at 42c and 40c of two cores and on high usage as games an movies and hd movies the temp rises to 45c and 42c.please comment if any thing more can be done to improve this. thanks in advance.

45 under load is is amazing, I would be happy to achive such numbers.

My new Toshiba runs at 60 under load.

45 is good don't worry.

Please mark as solved.
