Also, I think the whole "charge for 8 hours thing" is boilerplate ASUS stuff probably meant to ensure that people get it to a full charge state initially. I can see no good reason to charge it past 100%, because we should assume that there's a cutoff at 100% and that the thing doesn't continue to get stressed/heated past it's theoretical limits.
