As almost every user in Linux already knows, since 2.6.38 version the kernel has an important bug regarding battery management. It is said it’s going to be fixed in forthcoming 3.3, but util this, I’ve already applied this little changes on my OpenSuse 12.1
To do it, just go to YAST2 and open boot options, then clone your default kernel booting option and make changes there under “Optional arguments”
- FORCE ASPM
- pcie_aspm=force
- i915 OPTIONS ENABLE (enable some feats on intel machines to reduce power consumption)
- i915.i915_enable_rc6=1
- i915.i915_enable_fbc=1
- i915.lvds_downclock=1
I’ve just entered those values so I don’t have any result yet. In a few days I’ll write down my opinion…
