Remove the battery, plug the laptop up into the wall outlet and turn it on. If it boots fine then its your battery. Other then that the possibilities are this.

1. Your Processor has gone to junk
2. your hard drive has fried
3. or the pc board has fried.

Do you hear the hard drive spinning at all? if not this would be the first thing i would check. Only problem only real way to test it at home is if you got an other laptop put it in their and turn it on or buy a new one.

To test the board best way to do is open up your laptop by removing screws on the bottom, and looking over the bored and seeing if you see any burnt areas.

To test the CPU, really isnt a easy way to test this either, other then put a new one in.

IMPORTANT: if your laptop is under warenty opening up your laptop and trying to replace these will avoid your warrenty with this company.

best thing to do if under warrenty is to contact sony vaio,

if not take it to a repair shop, or try replacing the above things, starting with the hardrive

also make sure the ram is pushed into the board. (it looks like a rectangle)

Unit will not boot up. The Vaio logo and Intel logo will briefly flash on the screen and then the screen will go blank for good. The power indicator light and battery light are both on. The fan is on and...

It sounds like you have corrupted files in windows, or you have a problem with the hard drive. Remove the hard drive and re-seat it back in place, start up the computer! If no change, use the original recovery disc if you have one and reload the operational system, if that fails have the hard drive tested for bad sectors at the computer repair store.

Fter power switch put on it show blank screen and no sound only battery and power indicator is on but hard drive indicator is off. does that is a cause or some hardware problem?

it's possibly a hardware problem but you should make sure it isn't a software problem by putting in your system restore cd and restoring the DLL that you deleted, it could be an important system file. If it is a hardware problem, the first thing to try is taking out your memory and sticking it back in place, make sure it's clean and put it in there tight.
