Title:
Screen flickers, then computer shuts down unexpectedly
Status in linux package in Ubuntu:
Expired
Bug description:
I had been using Ubuntu 14.04 for a couple of months on my laptop, no
problems. It is a Pavilion dv6 3010us laptop, which is dual-booting
to Windows 7 and Ubuntu. Yesterday I noticed that my screen started
to flicker and suddenly my computer hard shuts down like someone
turned off the power or pulled the plug. I can boot back up and
operate Ubuntu for a few minutes and the exact same problem occurs.
Sometimes it will happen in the grub boot menu. I
The biggest kick is that my Windows 7 is running perfectly fine
without any of the same issues. I was suspecting an overheat issue or
power, but my battery is fine, everything is plugged in, and
temperature gauges with Speedfan (Windows) and an Ubuntu temperature
program both report temps between 48-60 degrees celcius, with the
shutdown occuring around the 60 degree mark.
I disassembled my laptop and got rid of some hidden doghair/dust in
the fan thinking if it was an overheat issue that my help it.
Unfortunately the same thing keeps happening. After some research
some people have suggested something about CPU Governor or some Ubuntu
driver issue. Perhaps the Ubuntu threshold for heat shutdown is lower
than in Windows? If it is a Ubuntu bug, please help! I can't even
operate Ubuntu to find out information if needed probably, because of
these unexpected shutdowns.
