Thanks for the speedy reply, I've just e-mailed the seller to see what they say
Incidentally I did manage to get it to switch on for about 30 seconds after a couple of days of 'rest' and the display appeared to be in Chinese so I would guess that its somehow lost its memory. Still doesn't seem to be recognised or charged by any PC's. :roll:
I managed to guess my way to the language selection screen and change it to English and also checked that it still had stuff on the firmware page before it died again. Starting to wish I had written down the firmware version incase I end up trying to do the reset/firmware upgrade thats mentioned in other threads.
