Hi everyone,
I have already post in this forum for a firmware problem, but the problem I have now was already starting to manifest itself.

My Kobo Aura HD consumes batterie when it's turn off (not in standby, realy off). In 3 or 4 days, the battery is totally discharged. It got worse, at the beginning, it was in 3 or 4 weeks.
This has the effect I can't charge the batterie by the micro usb port, I have to open the reader to charge manually the batterie (with a BMS charger), which is too discharged to be charged normally.
Do you know where this can come from? Has anyone ever had the problem?
I think a component of the motherboard is defective. Do you know where I can find a map of the board ?
Thank you for your help!
