I have a system with ubuntu-14.04.2-desktop-amd64 installed. It has stopped booting up after updating. As I power on it, screen glows for 1 sec and it shuts down. I have tried to open GRUB boot loader by pressing SHIFT key while booting but nothing happened, screen just glows for a second and goes off. This happens sometimes, most of time as I power on the wifi symbol gets on and laptop shuts down.The screen doesn't glow in this at all. I downloaded the Ubuntu from net and installed with the help of bootable USB on laptop.It's been 2 days and I have a lot of data in the laptop.

Any Solutions/Suggestions ? Thanks In advance.

  • This might be a power problem ... if this is a laptop try removing the battery and AC power for 2-3 minutes, then connect AC [no battery] and try to reboot. Post back with outcome. – pfeiffep May 15 '16 at 14:02

Is there any solution to it ?or How can I repair it? are there any issues with my Ubuntu.? any solutions? – TARUN JOSHI May 17 '16 at 4:00
  • If your laptop will boot using AC power ONLY and the problem doesn't appear perhaps there's a battery or charging problem. If the problem(s) are in the power system there's absolutely no way to determine the viability of the software intallation. – pfeiffep May 17 '16 at 14:15

  • I strongly suggest fixing one problem at a time, or at least in this case boot your laptop with the battery removed to proceed. – pfeiffep May 17 '16 at 14:21
