May these stuff are working, but I have my doubts. First I had to unload the nvidia kernel modules: # rmmod nvidiafb # rmmod nouveau
Then I loaded the acpi_call module: insmod acpi_call.ko before to try test_off.sh script I checked the battery state: # cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: discharging present rate: 1129 mA remaining capacity: 4453 mAh present voltage: 16410 mV # ./test_off.sh Trying \_SB.PCI0.P0P1.VGA._OFF: failed Trying \_SB.PCI0.P0P2.VGA._OFF: failed Trying \_SB_.PCI0.OVGA.ATPX: failed Trying \_SB_.PCI0.OVGA.XTPX: failed Trying \_SB.PCI0.P0P3.PEGP._OFF: failed Trying \_SB.PCI0.P0P2.PEGP._OFF: failed Trying \_SB.PCI0.P0P1.PEGP._OFF: works! and just immediately after that: capacity state: ok charging state: discharging present rate: 1166 mA remaining capacity: 4306 mAh present voltage: 17195 mV # lspci | grep -i VGA 00:02.0 VGA compatible controller: Intel Corporation Arrandale Integrated Graphics Controller (rev 18) 01:00.0 VGA compatible controller: nVidia Corporation Device 0a75 (rev ff) I had to plugged the adapter, because I had to let the laptop alone for 40 minutes (sorry! I'm not sure if this could be change the results) Now I unplug the adapter and I get this: # cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: discharging present rate: 961 mA remaining capacity: 5600 mAh present voltage: 16981 mV after a few minutes: # cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: discharging present rate: 949 mA remaining capacity: 5123 mAh present voltage: 16847 mV I think that is could be a good signal, despite the fact that lscpi still reporting the nvidia vga card.
