I have a Sony Vaio S series laptop and the  screen is completely shattered and i can't see anything.

I was wondering if someone could tell me the keystrokes needed to enable external display from the BIOS and include a screenshot of the BIOS.  I already can operate the normal windows on the external display but I want to change the BIOS settings so i can reinstall widows 7 and prepare my laptop for the upcoming Windows 10 update.

The model number is: SVS131B12M

The product name is: SVS1311N9ES

Any help is appreciated.

Thank You
