Here is question/answer just to help the community.

I just bought a new ASUS N750J . I had some issues installing kubuntu. Problems were the CPU FAN always running at full speed, battery not charging, not even detected...

I had difficulties to find a solution over the Internet. I have found it after two days of searching.

Everything was be related to ACPI (Advanced Configuration and Power Interface) in my case.

On my configuration ASUS N750J with kubuntu 13.x but I suspect on a lot of new laptop with some "smart" energy managers, the solution was to edit your GRUB entry and add the following parameter:

acpi=nolapic

GRUB is your boot screen, (default config, recovery config, etc). TO edit it, select the entry (or keep the default one) and press "e".

I have found various "solutions" some hacks like "pluggin/unplugging your power source 8 times and things like that. Most don't work and some only provide a temporary relief. The problem is at a very low level, some acpi tables get corrupted while dealing with the hardware. Somehow this parameter fixed my problem.
