When I pulled out my eBook reader today (a Sony PRS-350 - quite old, but new to me - I got it a couple months ago from a friend who wasn't using it anymore), I was surprised to find the battery dead even though I'd charged it a couple days ago. One of the reasons I've really been enjoying the reader is because the battery usually lasts a week or more, much longer than the 10" Android tablet I was using previously for reading eBooks. It's also much lighter than the tablet. So I plugged the reader in to charge at work, and when it was time to head home, I unplugged it. It restarted itself, and then complained there were no books, the battery was dead, and it was shutting down. Huh? Ten seconds after that, it restarted, and eventually told me there were no books, the battery was dead, and it was shutting down. Rinse and repeat. No amount of button mashing - including the classic "hold the power button for 5, no 10, no 15 seconds," or even the recessed Reset button - would stop that behaviour. What would stop it was plugging it in again: it goes into storage-only mode. So I read up on the Sony readers, and found out that there are books they just don't like, and this is their response. Which explained the battery going flat: I had put a couple new books on the device when I last charged it.
