Basically if I put it down on it, it locks up, then reboots and forgets where I had been reading.
Obviously, the answer is to just not sit it on that chair. Which I've been doing. But any ideas why?
The only thing I could think of is the angle it rests at (which isn't flat, it's a plastic lawn chair) is causing the battery to get a little bit loose. Either that, or the chair is haunted.
Not a major problem, but curious if anyone else ever experienced something similar.
