Hello at all, for some time I've been trying to reduce my laptop's power consumption (while running on battery power) on my Fujitsu-Siemens Lifebook C1320 with Debian etch. - I echo powersave to /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor - I installed laptop-mode in order to shut down my harddrive if it is unused. - I don't use swap, /tmp/ is a ramdisk-mount and /var/tmp links to /tmp, (I've 1 GB RAM) Thus my hd is barely used and my CPU reaches C3.
But for some reason, Windows is more efficient in power saving. (3,5h vs. 4,5h battery life while surfing wireless). Is there anything else I can do to save battery power? lspci says: 00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Processor to DRAM Controller (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03) 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 1 (rev 04) 00:1c.1 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 2 (rev 04) 00:1d.0 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #1 (rev 04) 00:1d.1 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #2 (rev 04) 00:1d.2 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #3 (rev 04) 00:1d.3 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #4 (rev 04) 00:1d.7 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB2 EHCI Controller (rev 04) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev d4) 00:1f.0 ISA bridge: Intel Corporation 82801FBM (ICH6M) LPC Interface Bridge (rev 04) 00:1f.1 IDE interface: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) IDE Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation 82801FBM (ICH6M) SATA Controller (rev 04) 00:1f.3 SMBus: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) SMBus Controller (rev 04) 02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5751M Gigabit Ethernet PCI Express (rev 11) 06:03.0 CardBus bridge: Texas Instruments PCIxx21/x515 Cardbus Controller 06:03.2 FireWire (IEEE 1394): Texas Instruments OHCI Compliant IEEE 1394 Host Controller 06:03.3 Mass storage controller: Texas Instruments PCIxx21 Integrated FlashMedia Controller 06:03.4 Generic system peripheral [0805]: Texas Instruments PCI6411, PCI6421, PCI6611, PCI6621, PCI7411, PCI7421, PCI7611, PCI7621 Secure Digital (SD) Controller 06:05.0 Network controller: Intel Corporation PRO/Wireless 2200BG Network Connection (rev 05) Regards Thorsten -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
