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.


Regards.

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.

Vaio vgn-fs790 will not power on


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)

Sony vaio vgn-fs775p laptop real time clock not keeping time


Hi

thank you for your query

If the time is not keeping up then it would seem that you will need to change your CMOS battery, this is a small battery found on the motherboard responsible for clocking etc

The battery is cheap to purchase, however I do highly recommned the laptop be booked into a reputable PC shop for replacement as you will need to take the whole laptop apart to get the motherboard

I hope this has been helpful

You can try doing these:

Clearing the CMOS, i.e. Unplug power cord and take out battery, then put them back in.

Cross check the components such as heatsink/fan, video card, and processor. It is never good to have a heatsink with the fan not spinning.

Check to see if the heatsink is cold, warm or hot. It shouldn't be cold OR hot.

SONY VAIO CMOS BATTERY LOCATION


Correction...

The CMOS battery is located under the system board, and is not accessible from under the keyboard.

The keyboard has to be removed in order to change the CMOS batter, (another reason why I don't like Sony laptops.)

Below is the batter I just pulled from a user's VGN-FS660\W 892cbd5.jpg
