Hi, I was wondering if anyone has had this happen to them. I have a Sony Vaio VGN FS640, and I was sitting at the computer doing stuff... and the whole computer shut off. I then tried to restart it to no avail. I was thinking its the motherboard. It just so happens my warranty just ran out, so I dont want to send it to the CheapSquad. Any comments would be great. Thanks

Since this is a laptop. I would check the battery and power supply brick before assuming its the motherboard.

First check the lights on the laptop and see if it recognizes the power cord being plugged in. Then check the status LED to see if its saying that its charging the battery. Lastly I would check them with a Multimeter.

Take the Multimeter and it to 24VDC touch the black probe to the outside of the jack that plugs into the laptop and the red probe to the inside of the plug. ( NOTE: NOT THE PLUG THAT GOES INTO THE WALL OUTLET TESTING THIS COULD CAUSE SERIOUS SHOCK) Observe the reading on the Meter and check it against the rated output of the brick (it should be listed on it). Next test the battery to see if it has any charge on it. I am not sure where on the battery to test it should have metal tabs on it one will be marked - one will be marked +. The red probe goes to the + the black probe goes to the -.
