If you're running the standard software on the N810, you'll notice that it reports two times: "Time left when idle" and "Time left when in use", the latter is what we're doing as well. > just as with the %, i would need to interpolate based on what i'm doing > what that "Time left" number means. Though in the N810 case, one could probably have a worst case (You know how much power the device can draw at max.) Maybe this worst case scenario is something we could use as well? > these devices go into very deep sleep states that just sip at the power, > but start drawing more or less power depending on the use case. and with > those devices, that can change from minute to minute. I'm absolutely aware of that.

Actually, no. I'm suspending my notebook all the time, and have never experienced this uselessness. The discharge isn't measure when the machine is suspended, only when it's actually running. (Doesn't cover the CPU sleep states (so-called P-states), as opposed to the system sleep state (S-states)). -- sebas http://www.kde.org | http://vizZzion.org | GPG Key ID: 9119 0EF9
