Question about Sony VAIO VGN-FS640W Notebook

1 Answer

Sony Vaio vgn-fs640w does not power up nor does it

I own a Sony Vaio VGN-FS640W. Couple of nights back, while I had been surfing the net since a few hours, I heard a pop sound all of a sudden, and the laptop turned off completely within a second. There was no smoke or nothing. None of the LEDs come on nor is there any sound from the fan or hard drive. Nothing! It's a complete dead duck. I opened it up but did not find any burnt spots nor anything out of whack. Battery is fully charged as off the night of incidence. HELP! I am using my iPhone to surf and find solutions. Thanks in advance.

    My original battery was replaced with a high capacity one about
    two years back. I currently use Sony VGP-BPL2 battery and there
    is no recall or issues with this one.

I went to the Sony Vaio support site for your model specifically and they mention a battery recall. There is a place on the site requiring specific information about your system and your battery to see if you are eligible for the recall. I would try this route to see if it resolves your issue. If not, I would say it is a blown transistor and you need to replace the motherboard. This means buying a new system, as Sony VAIO laptops are very proprietary and hard to find parts for.

Good Luck,

On VGN-FS640W screen is very dim, as if it were on battery. Is there some setting I can change to make brighter?


  1. Go to Control Panel -> Hardware and Sound -> Power Options.
  2. Click on "Change plan settings" for your laptop's selected power plan (either Balanced or Power saver).
  3. Now edit your plan settings by moving the sliders next to "Adjust plan brightness" at the bottom. You'll be able to change the brightness for when your laptop is On battery power, or when it's Plugged in.
  4. Once you've adjusting the brightness settings to your liking, then click on the 'Save changes' button.
