Hello, as the title says, the tabled do not respond to anything. The screen stays black and the charging led never turns on.
So far, i have observed that, when i plug it to the charger, the charger gets hot. Meaning it charges.
I have opened the tablet. The multimeter says the power is runing. 3.7v.
The thermal pad over the CPU is hot.
When i desolder a cable from the battery, the thermal pad cools down and the multimeter says 0v.
When i resolder the battery, the CPU starts to get hot instantly without me pushing the power boutton.
Before all of that, i have tried to charge for 24h then press power button for 30 sec then 3 times in a row.
Also, i have used the tablet for years and it happened suddently. The power boutton was not working very well either for all those years. I had to mash it for him to respond.
Please, help. Thanks.
EDIT : I figured out i can tun the tablet off through the power boutton. If i press it for 30 sec, the thermal pad starts to cool down. If i press again, it gets hot.
Also, if i turn it off and i plug the charger, the pad gets hot again. If i unplug, it gets cold.
It looks like everything is working but the charging led and the screen do not respond.
