I've got a Sony Vaio vgn-Fe31m. When I press the power button it flashes once and nothing happens. I've looked around the internet for solutions but couldn't find any. And I don't want to spend a lot to replace the whole motherboard as some people suggested, so I thought I'd try to fix it myself. Does anyone experience the same problem and/or have a solution? \r\nIt would be much appreciated! Regards, Richard.

Go to the device manager (through the control panel) and uninstall the drivers. Get new drivers through Sony Vaio support and see if this resolves the issue.

Hi,


This may cause by an electrical charge in the motherboard itself,Im not really sure how it affects the display of the computer.There's also a possibility that the problem is with the LCD cable or the LCD itself. Please follow this method since it usually fix such problem like that,


1.Removed the battery then unplugged the AC adapter


2.Press and hold the power button or the ON/OFF button for at least 30 seconds


3.Connect the power supply back to your computer then turn it back on.


4. Check if you will see any difference.


5. If nothing happens, try to press and hold Fn and F2 on the keyboard.


If nothing happens, there is a possibility that the problem is with the LCD or monitor itself, maybe it will need a replacement...


I hope this information will be helpful. Thank you for using FixYa...

Contact OEM for support motherboard needs replacement.

Yes the cmos battery is on the motherboard.

Every motherboard that runs a computer has a backup battery to run the circuit while turned off. This battery runs the real-time clock (RTC) and is referred to as the CMOS battery. By keeping the clock active and running even when the computer is switched off, power up/down cycles can be logged and before the internet, your computer could keep dates accurately. It also serves to maintain the system configuration settings in BIOS memory based on RAM or FLASH RAM.

unplug your laptop and remove the battery,and wait for a while...
then insert the battery and press on/off button...

no more then likely it sounds as tho your hard drive went ..not the mother board.

Possible hard disk failure or hard disk controller failure.
if you feel confident remove the hard disk and replace - obviosuly make sure that there is not power running and remove the battery - replace hard disk then battery then power and try again.

Do you get any beeps? is the hard disk clicking? listen carefully to it and post your findings.

It should be located somewhere on the motherboard wich means pulling the computer completely apart which unless you know what you are doing may be a little difficult for some, but not inpossible.
