I don't know what causes it since I just installed Ubuntu on my laptop.
Here is the issue. Ubuntu boots normally, so I can use firefox and such. However, after 2-3 minutes, laptop shuts down. (I see Ubuntu logo for 1 second before shutdown.)
Fans are usually working loud.
GPU drivers (5470) doesn't seem to be installed.
Anyone knows what can be the issue?
Ps. Previously, I used Windows 7 and it didn't create any issues.
