Restart the iPad
Press and hold the Sleep/Wake Button for at least 30 seconds, or until you see the Apple logo. This step forces a hardware shutdown that should override any software glitches that prevent normal operation.
Charge the Battery
If your iPad presents a black screen, the problem could be that the battery is depleted. If the battery is too low to support a low-battery message, the iPad doesn’t have enough power to display the charging symbol. Let the iPad charge for at least 20 minutes or overnight.
Check for Bad-Behaving Apps
If you frequently experience a full battery discharge problem, a rogue app may be the culprit. Go to Settings > Battery and scroll down to explore power usage. Apps that consume the most battery are at the top, with the percentage at the side. If an app consumes a large amount of battery power, close or uninstall the app, then see if the problem goes away.
Check the Charging Port
Sometimes an iPad doesn’t charge properly because the charging point is dirty, and the device doesn’t get a full charge. Dust or dirt could be inside the port. Every time you plug the charging port into the device, dirt and dust are compressed in the port. Use a non-metal tool, like a wooden toothpick, to dislodge the dust, then charge the device again.
Adjust the Screen Brightness
The iPad may be on, but the screen isn’t visible because the brightness setting is too dim. If Siri is enabled, ask Siri to increase the screen brightness. Otherwise, go to a dark room and increase the screen brightness. To increase the brightness, swipe up on the bottom menu and move the slider to increase the brightness. On iOS 12 or iPadOS 13, swipe down on the upper-right menu to access screen brightness.
Burp Your iPad
Some iPad users have reported on forums that burping the iPad realigns internal cables that aren’t properly connecting. To burp an iPad: If this procedure fixes the problem, the iPad suffers a hardware problem that will likely occur again. Consider taking your iPad to the Apple Store for repairs.
System Update
If you tried all the above fixes and your iPad screen is still black, try a system update.
System Restore
A System Restore is your last resort, as this step erases the data on the iPad. If you backed up your data to the cloud, your data reinstalls after the restore successfully completes. If you haven’t, take your device to an authorized Apple repair technician to see if there’s a problem with the screen or if another hardware glitch affects your iPad. After your device is repaired, you may not need to do a System Restore. If you still need to complete a System Restore:
