I just got my EZbook pro 3 version 4 a couple of weeks ago and it just did this to me too! I was so happy to see this thread.
I had it plugged in when this happened so it had a full charge. It took me 2 days to drain the battery. I just plugged it in to charge and tried to power it on after 30mins. Now I don’t even see the blue indicator light when I press power!
I left it plugged in and hopefully it will work. The AliExpress jumper store is not super responsive.
Any advice would be much appreciated
Cross your fingers for me
