Comment 218 for bug 760131

One more data point. On my Lenovo ThinkPad T410 (so, same as in comment #168) I was able to recover most of the Maverick-like battery life by updating to the newest BIOS. Before the upgrade powertop showed ~25W of battery drain w/o tuning, with pcie_aspm=force and all powertop suggestions done it went down to ~20W, and after the BIOS upgrade it is 16-17W, which is only slightly worse than with Maverick.

It can be further improved, now powertop shows the soundcard x2 taking 1.7W and used 100% (when no sound is played), that I will report separately.
