I formatted my HP Pavilion g6-2231tx Notebook, removed windows 8 and installed ubuntu LTS 12.04 on it.
With windows 8 the machine never overheats and remains cool. Also, battery backup is awesome.
But the day I installed Ubuntu LTS on it, it started overheating. And battery backup rarely exceeds more than an hour (In fact sometimes lesser than that).
I experimented with TLP also but nothing helps.
Please provide help if there is any solution from the Linux community or HP itself.
