Re: XPS L501X - switching nVidia off

  Thread Previous • Date Previous • • Thread Next 
WoW it's true, finaly that works :)

AFTER
cat /proc/acpi/battery/BAT0/state
present:                 yes
capacity state:          ok
charging state:          discharging
present rate:            1673 mW <---- to much better (kde show about 5:36hrs).
remaining capacity:      6899 mWh
present voltage:         12306 mV

XPS L501X
