Ubuntu 11.10 runs great, she likes the desktop and she boots it more often than Windoze... all is great except the fact that the battery dies twice as sooner as on Windoze. For example, it would last for at least 2 or 3h on Windows, while only 1 or 1 1/2 h on Linux. Here's what I've done so far to improve:

- disabled all services that are not needed
- did all the things suggested on this site -> Click


I suspect that either Sony is hiding their nice closed source tweaks to save battery life, or Ubuntu hasn't taken care of this issue well enough. Do you have any other ideas how I could solve this?

Thanks in advance!

interesting... i am still trying to figure out how to tell if it is enabled or not on my system, but for those who like to experiment (and aren't afraid of breaking their OS), ubuntu has released a test kernel for 11.10 installable as a deb package, more about that here - https://wiki.ubuntu....PowerManagement
i would be interested to hear the results of the test if anyone gives it a try.

mr. kernel hacker, are you rolling the patch into a custom kernel yet? any more insight?

[urandom]

just tried, all I can say is the patch applies fine (with a small 2 lines offset) on 3.1.1 (which, FWIW is also patched with latest bfs-415 and greg's current git 3.1 patch queue)

dmesg spits the same crap with or without the patch:

[	0.415249] ACPI FADT declares the system doesn't support PCIe ASPM, so disable it

looks like lenovo BIOS is badly wrecked anyway:

it looks like dmesg will report this message anyway, the patch does not modify this behavior, it's what happens after that changed.

 	}

now, *if* I understand correctly, the kernel couldn't get ACPI _OSC control:

[   	0.606222] ACPI _OSC control for PCIe not granted, disabling ASPM

so we really shouldn't clear ASPM state - which is the case without the patch -  and leave it to defaults.

i'll try to run this patch a little bit longer than 5 minutes and see how it goes...

so, using the patch on two machines since a week now, no breakage, stability issue, kitten suicide whatsoever until now. oh and no benchmark to post either
