I upgraded to Windows 8.1 from Windows 8 recently; for a week after upgrade the brightness control was blocked. However now the screen is not showing on start up at all.
Its a Samsung Laptop. On switching on the “Samsung Screen” comes on, however it goes off after a short while. On touching the touchpad, cursor can be seen momentarily. Nothing after that. Hitting F8 on startup did not lead to safe mode startup either.
Please suggest how can I now get back to a normal screen.
