I have a HP envy 14. And dual booting windows 8 and Linux ubuntu 14.04.

The problem is that it sometimes gets a little hotter than when booted with windows.
Also I see that Linux "eats" the power. Laptop can't cope with that hunger. Even in power cord it cannot fully charge when Linux is on.

Is there any power management tool and something that works like "coolsense"? Sensors don't work I guess. And even if they work the management by default is poor.

I am looking forward to hearing from you. Thanks in advance.
