Regarding screen turning off when the charger is removed.

[srinivas019]

My VAIO is a brand new one which i bought it 20 days back and the screen is turning off as soon as i remove the charger cable. and i need to connect the charger back and turn on the computer to restart the screen.

The best solution which i recommend is  :

1. Disconnect AC
2. Shutdown
3. Remove battery
4. Connect AC
5. Startup
6. Under the Batteries category, right-click all of the Microsoft ACPI Compliant Control Method Batterylistings, and select Uninstall (it’s ok if you only have 1).
7. Either you can go to start - my computer - right lick - manage - a new window is opening called computer management - go on device manager which is located under the Computer Management (local ) on the left panel and on the right panel you see Batteries - u can uninstall Microsoft ACPI and done 
8. Shutdown
9. Disconnect AC
10. Insert battery
11. Connect AC
12. Startup

Good luck
