My Gen3 which has been a very well behaved device for over a year, with almost no problems, has suddenly developed an annoying habit.
When the battery indicator gets to 70% and I try to turn off the reader, it switches off but the green LED stays lit.
Or, it freezes on the library page. Reset doesn't always work. Now I know the battery hasn't had time to run down completely, so the 70% is probably fairly accurate.
A secondary question: Must I buy a new battery from Bookeen, or can I buy any brand?
Please

me. If my Gen3 dies I'll be devastated.
