I was wondering if anyone has experiences with the current T430 Thinkpads and Ubuntu 12.10 or 12.4.
Background: I just got a X1 Carbon and was so disappointed by battery life - couldn't get idle power drain down below 12w when idling with reduced screen brightness, no radio and ubuntu 2d and after applying the common tweaks laptop-mode-tools, powertop GOOD things, and i915 kernel params stuff.
This machine wouldn't last longer than 2-2,5 hours for my usage (web development).
Long story short: I haven't given up Thinkpads alltogether and was looking at the larger devices. I like their keyboards, trackpoints and durability.
Does anyone own a T430 and get good batery life with it? Please write your processor model, applied tweaks and powertop usage when idling.
Thank you very much,
P.S.: Does anyone know if there is noticable differences in power consumption between the Ivy-Bridge i5s and i7s? I.e. i5-3210M, i5-3320M, i5-3360M, i7-3520M. Would I get significantly different battery life off them in day-to-day usage? I guess the faster processors draw more power at load, but they are also finished faster. So I supposed it comes down to idle power usage
