I have a HP Pavilion DV6 model 6173CL and I have this bug in all kernel version :-(

There's Another Linux Kernel Power Problem

as strange as it seems I might have spoken too much too soon.
So I was just using this hardened gentoo thing with tor (I do engage in youtube trolling form time to time), and suprisingly enough the battery lasted much longer than ubuntu 13.04 did...
as unscientific as it is I confirm the power regression affects all laptops

As always Larabel is [ full of crap ].
$ uname -a
Linux ultek 3.6.9-1.fu2013.x86_64 #1 SMP Sat Dec 8 07:26:15 EST 2012 x86_64 x86_64 x86_64 GNU/Linux
$ sudo dmidecode -s system-version
ThinkPad T420
7.31 Watts, and 12 hours of battery life remaining using kernel 3.6.9. This is the same sky is falling story he reported in 2011 that I also [ thoroughly debunked ] this time with a slightly different flavor. Move on folks, there is nothing here to see.
The only thing important to Michael seems to be ad revenue.

It so happens that most users will use the defaults, not the weird power thing. So the default tests carry much more value than tests with some custom config.

Originally posted by curaga View PostJust like with the previous bug, your results are invalid for the general case, because you use some weird power thing, not the default configuration.
