So this is similar to this question and this question except after restarting the laptop I now have a totally blank screen. I can hear the fan and the power light is on but the screen is blank. I tried hitting del to enter BIOS as the computer restarted but this didn't work. Any advice is really appreciated otherwise I'll call the manufacturer's support. After the I got the blank screen I opened up the back and checked all the cables and checked that the hard drive was connected ok - all fine.
It's an Asus laptop running Windows 8.
EDIT:
I've also tried removing the battery and holding the power button down to get the screen working but no joy.
