20 Most Recent Sony VAIO VGN-FS640W Notebook - Page 2 Questions & Answers

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,

5 have the sa0e *r6b3e0 as y64 can see.

i have the same problem as you can see. i have no idea how to fix it either

· First troubleshooting - When you turn the laptop on, are you able to see the splash screen? This would be the computer manufacturer's screen display that usually shows a picture but may also be text and usually appears right before the Windows logo screen. If the answer is yes, then more than likely, the operating system is corrupt. This can be caused by several things including viruses, power surges or hardware failure. If your computer hits the windows screen and reboots back into a loop, this is also signs of Windows being corrupt.

Solution - Take the hard drive out of the laptop and slave it to another working desktop computer to retrieve your data. You may need a special cable for this because the laptop hard drive is smaller than the cable in a desktop. This process can be done, taking precaution that both computers are off while slaving the hard drive. After you attach the hard drive, turn the desktop on, it will read it like another drive and you will be able to pull all of your information from it. You only want to grab the user files, not other data and run a scan to rid of viruses. Then attach the hard drive back on and reformat it.

· Second troubleshooting - If you hear the operating system chime but do not see a picture and all the lights are on, then this would indicate that the back light on the screen is out. You can test this simply by hooking the laptop up to a monitor and see if you get a picture. If the computer screen shows on the monitor, then your back-light is out. If it doesn't show up then your video graphics card is out.

Solution - If the back light is out, it is easier to order a new screen (new or used) from eBay and just switch out (simple process and you can find a replacement for under 50 dollars on eBay). If it is the video graphics card, then you can also purchase one from eBay and switch out (a little tougher because you have to take the top of the laptop off). You can get assistance with this from the manufacturers website (service manual) and pull specs for free.

· Third troubleshooting - To test the battery, take the battery out of the laptop and turn on with just the adaptor. If it boots, then the battery will need to be replaced. There is no way of testing the power adaptor but 85% of the time, this is the problem. Even if lights come on, the adaptor sometimes gets so overheated that it silently goes out but gives just enough power to make the lights come on. The power adaptor can be found on eBay for under 20 dollars and is cheap enough to replace (first) to make sure that is not the problem. The battery can also be found on eBay for under 60 dollars.

· Fourth troubleshooting - If you do not hear any beeps and the above solutions did not work. Then your motherboard has failed. This can be caused by surges or dust. You can purchase a replacement from eBay for a fraction of the cost and replace (this is tough and I am not sure if they have specs for this). You can do it yourself, just be sure and put everything back together as it was.

What generally happens to connectors, especially exposed to air is they oxydize.

Buy a can of "Contact Cleaner" from a local Radio Shack and spray it (through the thin tube usually provided) into the jack. One quick push, dont flood it. Take the earphone jack and insert and remove it several times, wiping off excess, which sould clear contacts and it should work normally again. If not it would have to be replaced which is no easy matter requiring an experienced Technician or Factory. Sometimes it cannot be replaced without damaging the Mother Board. This however sounds like a common problem the Contact Cleaner will fox

Cheers,

Good Luck :)

There is wireless switch in on the base of the unit. next to the mic in and headphones out. It will say "wireless" next to that. If it will not detect wireelss networks after that just enable wireless adaptor in wireless switch utility. It is in the system tray next to the clock.

I have a laptop that has been doing exactly the same. It started off with a fine pink line. After almost a year it now has gotten wider and has white lines and all other colours. It could work like that for quite a long period. It is a conection in the bottom of the screen but is so delicate... Only way to REALLY fix it is to have the screen replaced which could be quite an expensive thing to do

lemme know it is of green or yellow color question mrk

your hardrive is going bad cannot read the disk.take hardrive out and tap it slightly? then replace see if it makes a difference..

Is it ok if your files get lost forever?  If it is then what you have to do is when it says if you want to partition a hard drive space, you delete the biggest parition (which wipes any and all vista and files of the computer.)  Then it will ask you which partition you want use.  Use the one you just deleted, whhich is the biggest one.  It will ask you to format it and stuff, just go with it.  Then you will have XP instead of Vista!  (Warning: I warned you above that this way will wipe of vista and any other files-documents-photos-everything off your comptuer)

make sure windows media player is not starting on boot up if it is running in the back ground it can cause simialar problems.

To isolate the issue, i strongly recommend to connect the notebook to the external monitor by VGA port which had BLUE colored on the notebook. So that if it is normal then you need to confirm the issue is with the LCD display.

you want to be looking for the rtc(real time clock) which is a little unit not much bigger than ur thumb nail.next to it youll find the battery(sometimes heat sealed with plastic.)if you remove this battery for about 5 mins then replace it or in ur case maybe renew it this will reset bios to factory(also method for bypass passwords as every thing is reset)
you might also wanna check ur video card.(connections and dust)

Press the Symbol key on the keyboard. It works just like the Num LK key.

There should be a switch on the front of the computer that says wireless slide it to the right.

Did you download any software, regarding power management

it could be faulty software issues

or the battery may not be the right type

is it fully charged?

when upower up thecomputer enter in bios setup press del or F2 or F1 to neter in bios setup when u power up.
thenr eset bios defaults settings.
then check your hardiskk is deteted or not.
if sata is enabled then disable then press F10 to save settings.

More than likely you have a hard drive failing/failure.

You should have it looked at if you are not "comfortable" doing it yourself.

On the Keyboard, There should be a small little clamp housing. On the back of the key you should see a piece of metal that is sort of Staple shaped (A non bent staple) Just try and put the ends of the metal into the housing, Then apply a little amount of force onto the key to pop it back in.
Before applying pressure, Make sure that both ends are properly in place.

Hope this helps!
