Ipad Pro Not Charging From Computer Usb. If your iPad Pro still doesnt charge test a different accessory from the same socket. The power required to keep the screen on exceeds the charging rate of a standard USB port.
Connect your power adapter to a wall socket instead of charging your iPad Pro from a computers USB port. Clean the ports and connections. Check the computers USB port the iPads charging port and the cable for any damage or debris or dust that might be stuck and preventing a good connection.
The most common problem is that dust lint or another material has made its way into the port.
If your computer has only USB-A ports you need a USB-A to USB-C cable to connect to iPad Pro. Try a different USB cable or charger. The power required to keep the screen on exceeds the charging rate of a standard USB port. Yeah its the same little hack that we mostly remember whenever our device runs.
