Vaio vgn-fs790 will not power on

My vaio vgn fs-790 will not power on, and appears to not have any power getting to it. normally there is a power indicator that alerts you when you plug the computer in orange when it is off, green when it is on. no lights, no response to the power button. have tried multiple power supplies and indeed the power supply is NOT the problem, is the Motherboard Bad, is there a hard reset switch somwhere i can try?

If your motherboard isnt getting the power it needs it very well may be one of these two things. First i could be a bad connection on the board which you can't do anything about. and Second you may be connection the cords from the power supply to the motherboard incorrectly.

Make sure everything is connected properly and then try again. If your motherboard does turn out to be bad then you will need to replace it from sony try to get it returned and but a better system. alot of sites can custom build you one and not restrict what you can upgrade with. For example Cyberpower or Ibuypower.
(thats if you just bought it)

Does the Sony VGN SF790 support hdmi cables? I would like to connect to my Sony Bravia TV


Hi.

No I'm afraid not. It only supports VGA out. If your TV supports a PC input then a male to male VGA cable will do. VGA does not support audio so you will also need an audio lead to connect to the TV too.

It sounds like you may be having a video related issue. These issues may indicate that you have a problem with either your video card or your lcd screen. To isolate the issue, you have to connect an external monitor to the VGA port of the portable system. There should be an S2 button on your laptop which should allow you to switch videos. Press that and if the video appears on the monitor, then it is an issue with the LCD screen. If nothing happens, you have a video card failure. These are due for replacement already.

Sony vaio VGN FS 742W notebook Startup problem.When swithed ON,Vaio,Window XP screen appears and then window 'isass' appears & notebook swithes OFF automatically.Pl.advise solution for the above....


If Windows appears, and start booting, then the problem concerns the operative system and not the hardware.

That is good news, because all you need to do is using the original computer recovery disk, or finding a Windows setup disk to reinstall Windows.

To reinstall Windows, start the computer with the Recovery Disk or Windows Disk inside and chose Boot from CD when asked, then follow instructions.

Regards.
