iPad Pro 11" 4th Gen A2761 Not Charging Repair | Hidden CD3217B13 USB-C PD Controller Fault Fixed
Modern iPad Pro devices are incredibly powerful, but when charging problems occur, diagnosing the fault often requires advanced board-level troubleshooting. In this repair case, an iPad Pro 11-inch 4th Generation A2761 arrived at AppleFix Hamilton New Zealand completely dead and not charging. The customer had already tested multiple USB-C chargers and charging cables, yet the iPad showed no charging current and no signs of life.
Diagnosing an iPad Pro That Is Not Charging
When an iPad Pro refuses to charge, the problem is not always the charging port or battery. Modern iPads rely on sophisticated USB-C Power Delivery communication systems and power management circuits to negotiate charging voltage and current.
Common iPad Charging Symptoms
iPad Pro not charging
iPad Pro dead and won't turn on
No charging current detected
USB-C charger connected but no response
Battery percentage not increasing
Device only charges intermittently
iPad stuck on Apple logo
No power after battery drains completely
Charging port appears normal but device won't charge
Many of these faults require motherboard-level diagnostics to locate the root cause.
Hidden USB-C Power Delivery Controller Fault
CD3217B13 Charging Controller Failure
After performing advanced diagnostics, current draw analysis, and motherboard testing, the fault was traced to a failed CD3217B13 USB-C Power Delivery Controller.
This critical chip is responsible for:
USB-C charging communication
Power Delivery negotiation
Charging voltage management
Battery charging control
Charger detection
Power routing throughout the motherboard
When this controller fails, the iPad may appear completely dead even though the battery, charging port, and other circuits remain functional.
