Hello everyone, Powertop reports "no ACPI power usage estimate available" with x86_64 kernels 3.0.6-1 and 3.0.6-2. Downgrading to kernel 3.0.4-1 restored power estimates. Older kernels had always worked in the past. Processor is Intel i3, quad core, in a ThinkPad Edge 14 running Gnome 3.2 fully upgraded daily. -- Neal

I guess this will make it clear, I was looking for it too so serves as a reference to me :) https://bbs.archlinux.org/viewtopic.php?id=127795 https://bugs.archlinux.org/task/25845 -- Mauro Santos

Have you tried with powertop2 instead? powetop is not maintained any longer, so we should probably get around to updating to powertop2 at some point... (I have been meaning to). -t

@Tom Thankyou for pointing out powertop2. It allows for more control than the original powertop. The URL in the PKGBUILD is not correct because of kernel.org's changes. Googling for a new location was easy enough. @Mauro Thankyou for the information. -- Neal On Tue, Oct 11, 2011 at 12:20 AM, Tom Gundersen wrote:

On a related note - I also get this "no ACPI estimate" error, but only when my laptop is not on battery power. When unplugged, it gives estimates as desired. Anyone know why this would be? -- Scott Lawrence

Powertop measures the power requirement using the decharge rate of your battery.

Ah, of course. Thanks. (For some reason, I assumed there was an actual hardware bit dedicated to providing this estimate.) -- Scott Lawrence

If it was so easy, what was so difficult about posting the link here? clemens

@clemens Thank you for pointing out my oversight. There is a patched powertop2 in the AUR with the correct URL in the PKGBUILD. -- Neal On Tue, Oct 25, 2011 at 2:59 PM, clemens fischer < ino-news@spotteswoode.dnsalias.org> wrote:
