Some updates…

Yesterday evening it turns on again without doing anything! (only a full charge of battery in the morning)

It boots instantly three times; four attempt only with a long pressure of power button.

Very strange…

@chupa: yes, I have the warranty sticker over one screw.

I tried to hold down the power button for a long time (about 90 seconds) but nothing happens (no light, black screen) even after I press it another time.

The strange thing is last time it worked, it shutdown properly via Ubuntu Mate (yesterday afternoon).

Hi to all, my Jumper Ezbook 3 PRO does not turn on (until yesterday it worked like a charm with Ubuntu Mate).

No blue led light, only the charging light works.

@ds28: if you opened the case in order to unplug the battery, you lost the warranty?
