Today my Jumper EZBook 3 Pro also fell into sleep. I had bought it in November from Gearbest, its the item with 6GB RAM and 64 GB ROM. It arrived already with an unactivated Windows 10 version installed. I tried to activate with the product key, but I was told that the key is not guilty anymore because it was used with another computer. Then I tried the telephone activation. This worked for the ongoing session, but after reboot the same message was there telling me Windows is not activated. So I got into contact with Gearbest support and they finally, after many instances of messages to one another, they gave me a refund of 20 Euros. A few days back from now I bought a new Windows product key and tried to reinstall Windows 10 with the new Key. The installation process began normally, but after some time the screen went black and everything except the Power key seems to be dead. Even the BIOS was not accessable like before with the ESC key.
A few hours before I contacted the support of Gearbest once more and asked them for a confirmation for a 1 year free repair return ticket. Hopefully this will bring back my jumper into life. I will not open the item because guarantee is only when they item was never opened bythe customer.
Naomi, you are right, next time I willalso buy a more quality item+
