I found a way to increase battery lifetime to 4-5 hours in idle (power consumtion ~12W) by disabling the nvidia-card through an acpi-call mentioned here:
http://linux-hybrid-graphics.blogspot.com/2010/07/using-acpicall-module- to-switch-onoff.html for this you can't have the kernel 3.1.x or 3.2.x installed. i switched back to the latest official oneiric kernel (3.0.0-14-generic) these are the lines that work for me(executed as root): insmod acpi_call.ko echo '\_SB.PCI0.PEGR.GFX0._OFF' > /proc/acpi/call the dark side is that suspend/hibernating isn't working anymore. So i create a script to execute this magic lines only on demand. maybe there is a elegant version to provide a hide-my-nvidia-card funktion for users with optimus that don't need the nvidia card on ubuntu (like me). i'm now a little bit more mobile and my notebook isn't a heater anymore (if i don't want so) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/876854 Title: high power consumption on Asus X4GS(N43SN) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/876854/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
