Ok, I have few issues with this laptop and I suppose they are all bios related.
So, when computer is powered off completly, battery drains in few days.
After that, when I plug it in, cpu vent power up, despite computer not being powered off, and when I power it on, it turns off.
Power button does not work in windows (it should put windows in power down mode).
When you power down the machine, most of the time cpu vent turns on and I have to power it on and enter bios and turn computer off.
Demonstration is here on youtube:
