Hi all
Thank you for your replies. I have just tried the "5 minutes to shutdown" mode and it seems to work. However, will it be sufficient to save the battery? If the battery is made flat only with one or two reading hours, as I suspect, the problem will remain as before.
My firmware is 1.8 20130407 from
https://onyx-boox.com/support/firmware/. As I already said somewhere in the forum I bought my device at
https://onyx-boox.com and not at
http://ereader-store.de. Thus, unfortunately, if I well understood, I cannot install the firmware updates of booxtor.
