Notebook No Display

There is no display on the screen for my Lapbook Pro (4/64) after doing the latest Windows update. I had been using the machine perfectly for the last 4 months.

Although there is a light indicating that the notebook has power (shown by the left LED), it cannot get into BIOS page.

Tried to connect to an external monitor after switching on, the notebook still shows a blank screen.

Any solutions ? Thank you.
