Open the Vaio screen until you can easily access the keyboard.
Locate the plastic bar that borders the top of the keyboard. Insert the flat head screwdriver at one end of the bar and gently pry it up until you can grip the edge with your fingers.
Pry the other side of the bar up with the screwdriver and pull out the entire bar, being careful to mind the ribbon cord that connects the keyboard to the computer.
Remove the two screws on either side of the keyboard that secure it to the computer. Slide the keyboard up and place it to the side.
Remove the four screws on the exposed metal plate that covers the motherboard and remove it. You should now see the CMOS battery in the bottom-right-hand corner of the motherboard.
Remove the battery by gently pulling it up and off the motherboard. Replace it with the same model battery (available at any computer store or online). Reassemble the computer the same way you took it apart.
Do the following:
-unplug adapter from the wall -unplug from the computer side -remove the battery -With everything unplugged and battery removed, press the power button. Keep holding it down for 15 seconds Yes, nothing happened, that is ok. :) -re-insert the battery first -plug the adapter to laptop side first -plug adapter to wall socket Now, turn on the laptop and see if it powers on.
If you have a windows disc that came with the system, insert the disc while the computer is on. Shut the computer down. Turn computer back on. Your computer should boot to the disc. Delete partitions. Format the hard drive. And reinstall. If you do not have a windows disc contact sony to purchase a recovery disc.
