HI,
I have a sony vaio VGN-NW270F. It is running widows 7. A little while back I had a virus issue. I tried everything and ended up having to recover the entire computer back to factory settings. I ended up have to do this 3 times before it finally KEPT working. Then I thought I had it all working well all prog back on it, new sec software, netflix, itunes etc.. Worked fine and then it started shutting off by itself. Battery works and charges. When I get it started. all programs are there and it works fine and then it shuts off. I can tell it lasts longer on first boot (10 min ish) after that it will boot up and ask to start windows normally or safe mode. You can do either and then it will boot and after that last 2 - 5 mins and then shuts off.

It really doesnt seem to be very hot, so Im not sure if this is a cooling issue. I have blown it out. It is clean. Again, not sure if I can hear fan or not. But, before it got pretty hot and never did this. So...... Any thoughts....

Thank You So Much

It sounds like a hardware issue to me. If the CPU gets hot enough, it will turn off as a self preservation mechanism. Is the laptop still under warranty?

You could download and run CoreTemp. Through the options, set it to start with windows and keep it open on the desktop. Monitor the CPU core temperatures until it shuts off. If the CPU is getting hot and the CPU fan is working, you should feel hot air coming out of the exhaust vent.

Regards,
Brooks

Based on your past experience, I would definitely recommend a fresh installation of Windows. Remember to backup you data before you do this.

But first:

Please use a program like HW Monitor to see if your CPU or hardware is overheating. Also try running the laptop directly off the mains, with the battery removed.

Mains? just straight ac power? As far as windows. I dont know what else I could install. I have tried repair and everything else out there, ad nauseam . I had even posted that problem on here. I will try without battery. Even if the fan had failed, it should last longer, and once I had it on for 3 hours and shut it off myself. Only to find the next morning it was doing it all over again.

I am really at a loss?????? Thanks For The Help

please try and blow out your cooler with some airgun... its most likely a overheating issue on the CPU, seeing it is in certain amount of time...

For information if you are not sure, in Bios ((F2 OR DEL at startup)) is normally a temperature monitor on your cpu

If not :
http://www.techpowerup.com/realtemp/

If that is not the case... please go in safemode and run MSCONFIG.EXE from your start menu and see if you can uncheck any weird things in your startup list... ((4th tab))

If both things don't work... i fear it is best to backup your system and reinstall...

If you have warranty card, plz take that and ask the service provider to resolve your problem.

Some possibilities:

Your restore image has a virus in it.
You restore image is simply corrupt.

Resolution: Document your Windows Version, license key, backup your data, and obtain a copy of your Windows version on CD or DVD. (Bit-torrents are useful here) Also, obtain a copy of your network driver onto a disk or flash-drive. Then Blow away all partitions 1st (delete), reformat hard drive, then install O/S and then network driver. Eventually you will need to download all of the system drivers or some of your hardware will not operate properly or at all.


Other Possiblities:

CPU and GPU Factory Shim (piece of Crap)has shifted,moved, or deteriorated from heat.
Fan may be working part of the time.

Resolution: Install Copper Shims over top of CPU and GPU (sandwhich between lithium grease)There are videos on Youtube.com about doing this. Refer to those videos. I'm not getting into it here. But this is a common problem with many laptops. The factory installs a cheap gortex like shim to fill the space between the CPU and heatsink, the same with the GPU.
While you are in there, replace the fan.

my 2 cents, hope it helps someone.

Peace!

Try running a diagnostic test for the hard drive.

You didn't report how the laptop performed while operating on A/C power with the battery removed per ReviverSoft. If there was an intermittent problem with the power supply cable or the power jack, you would expect the computer to shut off sooner.

Were you able to get a CPU/GPU heat reading? Post a photo.

Does your computer have "One Click" Vaio Care Diagnostics? If so, what does it report?

You could attempt a hard drive diagnostic test using your drives manufacturer's DOS diagnostic software: http://pcsupport.about.com/od/toolsofthetrade/tp/tophddiag.htm as recommended by jhayz. The Short test would take only minutes; however, the Extended test, several hours.
