I've left my kindle on charge for the last 36 hours and I've just taken it off the mains adapter.
However, the battery symbol on the top right-hand corner has an exclamation mark (!).
Obviously, I am surprised because I've never seen this before.
What does it mean?
Does it indicate that the battery is fully charged, or the battery is virtually flat despite the fact I left it on charge for the last 36 hours?
