From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'll try other kernels then, but I don't know how to check if the system is actually powered off or not without waiting 8 hours and checking the battery drain XD perhaps the
haltcould be the keythanks!! I'll update the thread if I'll discover something new
probably related to this kernel bug though:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2059738
downgrading the kernel should fix it as a workaround it would seem.
the halt command is like a handbrake for the kernel, so it basically shuts everything down hard and stops, but it does not power off the system without you telling it to, so that is why your LEDs stayed on after you used the other parameter.
you could just try to downgrade/ upgrade the kernel, do s shutdown for a few hours during daytime when the computer is not beeing used, then turn it back on and check the percentage.
you will see the drain if it's not a full night, but it might not be so drastic.
if it's completely shut down there should be no loss in percentage, even for a short period of time as there probably is now..
I'll try to think up another solution, but a bit busy today as I mentioned on the last post
