I recently bought a laptop boarding a skylake i7-6700hq processor, and I managed to install Ubuntu 16.04, however, I noticed that the laptop was overheating resulting to a very short battery life while on Ubuntu (1,5 hour while it lasts 6 hours on Windows).
So I ran powertop , and I noticed that my processor never goes below the PC2 state, and thus even on idle. I also tried running powertop –auto-tune and even if there is a slight improvement, the processor never goes below PC3.
I've also tried upgrading the kernel, moving from the 4.4 ubuntu to 4.7, but it had no effect.
To be frank I'm completely clueless against that issue, that's why I'm coming to you.
I'm also attaching powertop output.
Thanks for your help !

Best Answer
First, update the motherboard firmware to the latest, and keep it up-to-date.
Second, please install the intel-microcode package (and you must use version 3.20160714.1 or later, so get it from Ubuntu YY or from Debian).
Ensure you have microcode 0x9d or 0x9e after you reboot (in /proc/cpuinfo or in the kernel log).
This will help some (it will at least get some potentially crashing behavior out of the way), but it will not solve everything. The NVMe issue with PC3 remains, and that requires code that is not yet in the Linux kernel, and possibly some information Intel did not tell anyone about yet.
