I have solved this problem,

first, open your lid & keep it opening

then, wait for a while,( about 20 seconds)

finally, press the power button

you will see your screen light up.

if you have further question,DM me @beritachang.

Mine gave the same problem, ended up waking up, but when sleeping again no more wakes up

Any tips?

Tks
