How can I make the tablet auto turn on on Android when the battery is connected?

Question

Android

Good day!
There is a tablet, the battery is dead, but I don’t need it from the word at all, because. I will use it in the car.
I unsoldered the battery, I directly supply 3.7 volts through the stabilizer, deceived the charge controller and now the tablet thinks that its battery is fully charged and everything is ok.
The problem is that to turn it on, you need to remove the tablet from the holder (because the holder completely blocks the power button and the usb socket).
So, how can you make the tablet automatically turn on when power is applied (roughly speaking, as if the battery is inserted)?
I found how to make auto-power on when charging is applied, but I can’t find it when the battery is connected, please tell me how to implement it (ideally, programmatically, without emulating the button closure, because you can’t crawl up to it on the board, but in extreme cases maybe hardwired)?

Most likely not. Didn't you think to solder the wire to the usb contacts inside the case so that the tablet saw the power source as external?
