    Re: suddenly power off without any warning

    Just a tip: Use the # code tag instead of the HTML icon. You can also select the code in a quick edit, hit the quote icon then replace where it puts [quote] with [code] at both ends.

    I would be thinking a hardware issue. Does it happen in all OSs and how old is the computer?

    Re: suddenly power off without any warning

    On first sight, I would be thinking of several things that can cause this:
    - power outage with empty batteries
    - overheating and emergency shutdown

    If it is not too long ago, you might find more information about the issue in the system log file /var/log/syslog, which is also accessible through the Unity GUI.

    This may sound crazy, but have you setup the proper keyboard during install... Maybe an incorrect key layout is either sending your laptop to sleep or powering down...
