Hi! >From your talk i have two theories you can give a try:
1.- Your Linux is not using "power save" features, so it drys your batt faster than windows (the most probabbly i think) 2.- Your Linux is miss-meassuring the battery (it thinks is empty, but have yet more power. More rare, but also seen.) For the first theory (1), i will check if "laptop-mode-tools" and "pm-utils" packages are installed. In my Debian the first is on charge of spin down hard drives and send "powerdown" state for unused peripherials. The second are "power-management" tools Also take a look at some other tweaks you can perform: http://www.thinkwiki.org/wiki/How_to_reduce_power_consumption Also interesting for you will be the "powertop" utility to set up powersaving setting and diagnose power consumption. I have found also a custom package claiming it handles "advanced power management" fot thinkpad laptops. If the "laptop-mode-tools" doesnt work for you, give it a try! In Debian you can tweak some stuff in kernel in order to save some power, the more interesting should be the laptop mode: $echo 5 > /proc/sys/vm/laptop_mode ... but you can also turn off unused ports, limit screen backlight, turn off the lasers (CD/DVD) For the second theory (2) i have no idea how to do that, but i remember a similar problem year ago, and someone got to cheat kernel to think it had more battery (and it worked). It had something to do with how many cells the system thought was available. Take a look at the special files here, they store all information and parameters that the kernel has about your battery: $ls /sys/class/power_supply/BAT0/ then you can "cat" to read values, like for example, full charge and current charge of battery installed: $cat /sys/class/power_supply/BAT0/charge_full $cat /sys/class/power_supply/BAT0/charge_now one last advice: do one change at a time, check resoults! Good luck and share you experiences! :) El vie, 01-01-2016 a las 16:56 +0100, megagolgoth escribió: > Hi, > > I've got a problem with the last build (20150518, and after a short > test today, also with the 20150208)) of Libreboot for x60 (fr > azerty keyb).
