Hi, I have had a Samsung 700t notebook for just over a year. Last month, for some reason, when I press the power button to turn it on (after a shutdown), the power light and fan comes on but I have a black screen. I press the power button again (everything goes off) and I wait a minute, then press the button again and it starts straight away perfectly. I have tried taking it back to a previous windows update it didn't change, so updated windows and samsung drivers. I don't have any problem waking from sleep or hibernation.
The same thing happens if I try to do a restart - 'restarting windows' comes up, light/fan on but black screen, power off, power on and it starts ok!

Would anyone have any ideas? I have searched the net but cannot find anything similar.
