Please HELP ! My Hi12 doesn't start anymore

Dear guys,

maybe one of you can help me… I didn’t use (and recharge) my Hi12 for a longer time…and now, when I try to use it, nothing happens. It won’t start/boot, it doens’t display anything (the screen stays dark).
Normally there lits a little orange LED during recharging…but NOTHING !!

Is there no way to get it working again ?

I really hope that someone can hlp me to get this tablet up and running again…
Thank you very much in advance

Hubert
