If you say tumbleweed, you run a 3.0 kernel which is known to have power regressions: http://www.phoronix.com/scan.php?page=article&item=linux_mobile_uffda&num=1 Kernel 3.1 is reported to have even more: http://www.phoronix.com/scan.php?page=article&item=linux_31_power_regress&num=1 I have a clarkdale notebook with Intel graphics and experienced increased heating since switching to a 3.0 kernel. I could improve on this using kernel parameters as described in http://www.phoronix.com/scan.php?page=article&item=intel_i915_power&num=1 2011/8/30 Jeff Hoare <jeffhoare@xtra.co.nz>
Hi,
I have a thinkpad e520 that I am running opensuse 11.4 tumbleweed on. While most everything works I notice that the battery life is quite poor under linux compared to windows. I can only get maybe a couple of hours under linux but 4-5 hours under windows. These have dual graphics (intel + AMD Radeon HD 6630M switchable). I have blacklisted the radeon module so that (hopefully) only the inbuilt intel graphics is used. The radeon module is no longer loaded and intel sandybridge is shown as the driver in gnome, but still the battery doesn't last long. I do notice that the fan seems to be constantly on. Is there anything that I can try to improve the battery life or is this just the state of things under linux for this type of laptop
