I have a core-i3 Win8 upgraded q702. My battery life w/o dock is up to 2h30-3h, and only ~5h with the additional keyboard dock. This is similar to the what is reported in that review: Fujitsu Stylistic Q702 review - reviews for UK IT professionals - V3.co.uk From your experience, do you know what could make the difference ? Any driver involved ? what settings do you use when running on the battery ?
