iPad won’t turn on

If your iPad has recently been “repaired”, you may need to seek assistance from whoever repaired your iPad.

Apple generally don’t repair an iPad, but will instead exchange an iPad in need of repair with a reconditioned iPad of the same model and specification. Unless your iPad was repaired by Apple or an Apple Authorised Service Provider (AASP), you will forfeited future hardware support from Apple

If your iPad is unresponsive, connect your iPad to its Power Adapter and allow the iPad to charge. Then, while still connected to external power, try a forced-restart:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

If iPad still doesn’t turn on, or if it gets stuck during start up, see the Apple Support article If your iPhone, iPad, or iPod touch won’t turn on or is frozen. Or if your iPad isn’t working correctly after you restart it, see the iPad Support website.

If your iPad was repaired by Apple - and you continue to experience difficulties - you can seek assistance directly from from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:

Similarly, you might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess your iPad:

I had a similar problem with my 4th gen iPad Pro, took it to the genius bar and they were able to reset with "the computer in back" but after the reset I can only charge using a usb c charger and a thunderbolt cable..I would try that method.
