Hello! I'm trying to get some more battery time by deactivating the discrete graphics card. Maybe someone can give me a hint ...
I tried the acpi_call power off method from http://hybrid-graphics-linux.tuxfamily.org/index.php?title=ACPI_calls for my laptop. I can't see any increase of battery time. Using archlinux, acpi_call-git: # sudo dmidecode -s system-product-name && sudo dmidecode -s system-version TravelMate8472TG Not Applicable # lspci -vnn | grep '\''[030[02]\]' 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 18) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller [0300]: nVidia Corporation GT216 [GeForce GT 330M] [10de:0a29] (rev a2) (prog-if 00 [VGA controller]) # sudo 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: works! This fits to the report on the wiki page. GNOME reports no difference in battery time. Is there something wrong in the report on the wiki page? - Or did I miss something? Should I check the battery time in a different way? Help is greatly appreciated!
