Big news! I finally succeeded in failing!
Yesterday, the battery was around 45%. I used the switch and as I was release it, I put my Mighty Bright TravelFlex light on the screen (the clip part, more specifically). About 8 hours later, the Mini has shut down by itself due to a low battery level. I turned it on just to check the battery and it was at 1%.
Good part is, now I'll be able to try Jgoguen's plugin, since I was waiting for another full discharge to plug the Mini to my laptop
TechniSol, I see your point, but can we state for sure that the proper behaviour for a device in use (synchronization, dictionary search, highlight...) is not to go on with it, even in sleep mode?
Off topic: don't forget that some people here are living in countries they're not coming from (Mrs_Often, paola, stitchawl come to mind). So the location details are sometimes different from the user's native language.
