Very High CPU usage on HP dv7 Laptop when IDLE

Question

I'm pretty new to Linux computing. So I finally thought of giving Ubuntu a try, by dualbooting it with Windows 8 on my hp dv7-6006tx laptop. Laptop Specs

But after installation, I immediately realised that the fan of the Laptop is spinning very hard and there's a considerable amount of heat underneath, when the laptop was on idle, IE NOTHING RUNNING. - this rarely occurs when running Windows (Unless I'm rendering or encoding movies).

So I'm not sure if this is maybe an incompatibility issue, or if I just need the latest driver software and that things? What also concerned me was how quickly it drained my battery. It didn't even last 30mins, where I can use it for over 2 hours on Windows.

Please advice me, as despite of this issue, I'm really enjoying Ubuntu and would love to make further use of it! :-)

Thanks!

Open a Terminal and type: ps -eo pcpu,pid,args | sort -k 1 -r | head -15. Please add the output to you question. — serve.chilled, Jan 29 '13 at 08:50
