Having problems with your Sony VAIO VGN-FS640W Notebook ?

CMOS Battery My Sony Vaio laptop stopped working when you turn on the laptop nothing happens. Tested the hard drive on a friends Vaio and it booted ok and I tried my friend's hard drive on my Vaio with no luck. Connected an external monitor but again. The hard drive sounds as though it is spinning but nothing else on the system board works even a boot CD. Can you tell me if a Sony Vaio Model VGN-FS740/W has a CMOS Battery and where I can find it. The laptop was losing time and I recall update Bi


Answers :

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)
\015\012you might also wanna check ur video card.(connections and dust)
I beat the laptop up and it worked!!! it was between the headphone jack and the keboard, in that area.
