Hello,

I was using my Sony Vaio Model VGN-FS810 or PCG-7G2L a couple of months ago and everything was working fine. Then all of the sudden it just shut down to a black screen. At the time I was plugged into the AC adapter which was plugged into the wall. There was not any lightning in the area or anything like that and everything else in my house is still working fine. Since this time I have been unable to get the laptop to power on. None of the lights on the laptop come on, but the one on the AC adapter lights up. I have checked the output on the AC adapter with a volt meter and it seems to be correct. I have removed the battery and tried to power on, but nothing happens. I have replaced the battery with a new one, but nothing happens. I searched this forum, but was unable to find anything about this particular Sony except for replacing the key board. Any ideas?

There are many similar posts identical to yours and it amazes me that they are all Sony :O

It's possible your motherboard may have died. The only thing I can suggest is disconnecting the power cable, remove the battery and press the power button for 30 seconds.

Try powering again and see if anything comes on.

So, any resolution? I have had a dead VGN-FS830/W in a drwaer now for 3 years with only 1.5 years of light use on it. It was a great machine. Until it died. Usually I can bring any computer back to life if it has a pulse. But zip, zero, nadda power...then unless it is a Tower and I can change the power supply, then I am dead in the water, along with the Vaio. \

Tried the 30 second power sequence reset without battery. No go.

Thanks.

You other option could be to take it to a Laptop/Electronics repair shop. Some can diagnose the problem for a very fair price - it could be something as simple as a bad diode on the motherboard.

There are several thing that could be causing your problem. 1) The power "brick" could have a bad/ broken connection. 2) The laptop could have a bad connector on the system board. 3) Internal bad components on the main board. 4) I've seen a bad battery take down the power brick to the point that the system would not boot.

What to do:
Remove the hard drive, and all but one stick of memory and the battery. Try to power on the system.
If no power, try the memory in the other slot.
If no power try the other memory stick using the same process. If you get power, replace the things you removed one at a time. until it fails. If it doesn't fail, you've fixed the problem. If it fails, you have found the problem. If this process doesn't turn up the problem. Professional help is called for. This could mean a power "brick" or motherboard replacement.
Good luck.
