Computer: Samsung N150, OS: Lubuntu 14.04, dual boot with windows 7

I am a non-experienced user. I got a black screen after closing the lid, and restarting the computer from the on/off button does NOT work. I get the same black unresponsive screen, although the hard drive is running.

I have tried:

  • Plugging in a different monitor
  • Some keyboard combinations
  • Booting from the USB drive I used when installing Lubuntu

Nothing has worked.

Can you boot into recovery mode from grub bootup screen? –  sumwale Jul 20 at 12:04
    
Grab a copy of Super Grub Disc 2 and boot up from that. It'll find your existing grub installs. Select yours and edit it before booting. Add the following right before quiet splash acpi_sleep=nonvs If your PC is stuck in suspend, this should jog it out. –  amanthethy Jul 22 at 7:38

1 Answer 1

Could the computer boot from a CD like Super Grub Disc 2 if it was unable to boot from an USB?

I am a non-experienced user too, but this sounds weird. Can it happen? Can you enter the BIOS after switching the computer on? I mean if you are sure that you reach to switch the computer off. Have you tried pressing and holding the on/off button for several seconds in order to force the shut down?

I am sorry in case my bad English sounds rude.
