Chosen Solution
I tried to turn on my tablet and it doesn’t respond to the power button. I have not used it for a while, but the last time I did, it worked perfectly.
In most cases, the battery is just drained. Charge it for a little while, maybe a minute. Then, turn it on. If that doesn’t work, the cause could be coming from the power button itself or the battery.

this did not help me at all , and it did not work I am still having the problem . Do I need to have the software installed all over again ? my warranty is old what do I do?
