Sony Viao laptop battery not charging

mhtplsh · 07-05-2007, 04:55 AM

My battery is not charging. The battery is ok. The power supply/adaptor is also ok. Now i hv to remove battery to use viao on mains supply. This means the battery charging circuit is defective. Looking 4 solutions.
Sony service station people r asking $1100 as repairing charges.

That would likely require a motherboard replacement where the cost of the repair would likely exceed the cost of replacement unfortunately. How did you test to determine that the battery is OK?

From the fault i can understand that the battery charging circuit IC is defective. This happens due to voltage fluctuations. Can i get the service manual somewhere or not?
The computer works perfectly on adaptor.
Waiting for quick reply now,

What model is it? Unfortunately the manufacturers don't like to release service manuals, but I can look if you post the model.

The model number is
Sony Viao PCG-799P.
Hoping that i will get the service manual.

Are you sure? That model does not turn up anything on Google and is not listed on Sony's web site. Double check the model number.

I have found these models:
PCG-705
PCG-707
PCG-707C
PCG-711
PCG-717
PCG-719
PCG-723
PCG-729
PCG-731
PCG-735
PCG-737
PCG-748

The model i mentioned is on back side label. But near keyboard it is mentioned as VGN-FS15GP.

Unfortunately Sony does not seem to be releasing any manuals for any of the PCG-700 series. Sorry I couldn't find one.
