Greetings,
I have a question concerning my boox M90. May be someone here can give me a good advice about it.
It happened four times already that my M90 stopped reacting while I was reading a book in a pdf format (approx 4 mb, no pictures, firmware: 1.5.1). I thought that the battery was empty, but the charge indicator shows that the battery is 80% full. Still, if I recharge the device for an hour it starts working again.
Once it happened when M90 was connected to the desktop and windows made a message "the system cannot recognize the usb device".
Any help or advice how to fix this problem is greatly appreciated
