Chuwi hi10 CWI515 (1611) does not turn on

My tablet does not turn on after I turn it off, nor does the charge LED light up. I’ve tried all the methods I’ve found on the internet, but nothing works. All you do is press the power button for 5 seconds, the USB ports will power up, charge the phone, and the external hdd will turn on, and it won’t do anything.
I tried to take off the back cover, unplugged the battery cable, then plugged it back in, it didn’t help either. I’m very sad :frowning:
