An iPad Pro 11 inch with the M4 chip that will not charge is dealing with a cable, an adapter, a dirty port or a charging pause, and the checks go in a short order. The iPad Pro charges through its USB-C port, which is also a Thunderbolt port, and the first thing to know is that it needs a decent supply: a weak USB-A adapter or a phone charger may deliver too little power for it to charge while it is in use, and the screen will show a charging icon yet the percentage barely rises.
The checks in more detail
Use the adapter and cable that came with it or an adapter of at least 20 watts with a USB-C cable that carries power, and plug the adapter into a wall socket, not a computer port. Look for the lightning bolt on the battery icon, and for the charging indicator in the status bar. Try a different cable and adapter, since a damaged cable is the commonest fault. Check the port. The USB-C port collects pocket lint, which stops the plug seating fully; with the iPad off, use a wooden toothpick to lift the lint gently and never a metal pin.
A plug that wobbles in the port is a clue. Restart the iPad by pressing and releasing Volume Up, then Volume Down, and then holding the top button until the Apple logo appears. If the iPad is completely flat, leave it on the charger for half an hour before it shows anything. Settings can make charging look like a fault. Optimized Battery Charging pauses at eighty percent when it expects you to leave the iPad plugged in for a long time, and shows a message about it;
tap the message to charge to full, or look at Settings, Battery, Battery Health and Charging. A warm iPad slows or stops charging to protect the battery, so take it out of its case and out of the sun. If the iPad runs hot or the screen shows a temperature message, wait for it to cool. Update iPadOS in Settings, General, Software Update. Apple Diagnostics and Apple Support can test the battery and port; contact Apple with the serial number if a clean port, a known-good cable and adapter and a restart do not help.
