Hi, Thanks for the suggestions. I tried the options you mention regrading the intel module and they did not seem to make much difference to the time available on battery. The cpu does not seem to be excessively hot (i.e arounf 31c). I also retried vga_switcharoo (after I reenabled the radeon driver) turning the unused graphics off but this didn't make much if any difference. I did run powertop as suggested and this shows the i915 module as top of the top 10 it mentioned disabling nm_watcher (sorry can't remember exact name) but this and the other suggestions it made didn't help and infact the suggestion regarding usb autosuspend didn't help my usb mouse one bit. I do notice that in linux according to powertop my power consumption is quite high perhaps 22-23watts and even when the display dimmed with no activity this only dropped to 19watts all this even though according to powertop the cpu spent most of its time in c4 state which is suppossed to be desirable. Under windows the thinkpad power manager says that I am using around 6watts average and even while I'm typing this email usage is < 10watts. Is this normal under linux (i.e has power consumption always been quite a bit higher) or has this been introduced in recents kernels? I guess the problem for me is to effectiviely use the newer hardware I will neeed to be using a more recent kernel is that correct?
