I suspect the battery on my clip is dead (and hence my Clip is dead). It was working fine two days ago. Yesterday, it wouldn’t switch on, but when I plug it into USB it works and connects and is recognised by the PC. However, as soon as I disconnect it, it goes blank (usual behaviour is for it to update database for a couple seconds). Thinking the battery was really flat, I left it charging overnight (more than 12 hours) but nothing has changed.
Is there anything left to try, or do I just bin this thing? 
This is very frustrating 'cos it’s just been a year so the warranty is gone!
