I have a couple of symptoms that make me think Ubuntu has some problems identifying all the components of my laptop (Asus N56VJ-S4051H).

1. When starting the computer from the OFF status, the fan goes to full speed just after the boot manager (EFI) chose the OS. The fan stays on!


2. The battery symbol in the task bar doesn't seem to recognize the battery reliably, esp. when AC power is connected as well.


3. The battery indicator starts blinking once on battery and stays on.


4. The battery is not being charged while the Ubuntu is running.

I didn't have these problems with Windows 8.

I had to switch to a Linux system after Windows 8 got on my nerves too much...

Could you please help me solve these issues or point me to a direction where I can find further information?
