I'm wondering if anyone has had the same issue and knows how to fix this.
Today my computer has just started going into hibernation mode at random intervals.
I was using the computer at the time when this began and was not running any new programs and have not downloaded anything new.
I have tried checking in the settings to change the time for sleep mode (they're set to never), I have turned off hybrid sleep mode, I have also used the command prompt "powercfg.exe /hibernate off" to switch hibernate off entirely and restarted the computer after these checks to see whether it would fix it and still it is continuing.
The time between hibernation varies, after re-logging in it might go straight back in hibernation after 2 seconds, or it can take a few minutes but nothing has stopped it and I have been using the computer all the while so it is not a 'time-out' hibernation.
