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.

The charger may be bad, will it charge the battery? a common problem is the DC jack in the laptop breaks connection on the motherboard internittent operation or no power and shut down. If you can sub the charger that will tell if the power supply is bad or the problem is in the laptop. If the computer is the issue I recommend a professional because it will require extensive parts removal.

I had one with the same symptoms, the way i fixed it is by taking it all apart and resolder the system chasis grounds on the mother board, then reseting the motherboard's memory battery. A bit complicated for those with little knowledge on computer repair. You may have to take it to a computer shop, or try fixing it yourself. It took a while to figure it out.
