  4. D
    Execution of a full battery deep-discharge cycle to recalibrate port power distribution

Cevap

The technician must verify that the laptop's USB Type-C port supports DisplayPort Alternate Mode or Thunderbolt protocols.
Physical USB Type-C connectors do not automatically transmit native video signals unless the laptop motherboard controller explicitly supports DisplayPort Alternate Mode or Thunderbolt protocols.

Adım Adım Çözüm

1
Analyze the reported symptom and connection type.
The USB-C dock provides power and data functionality, but fails to display video on external monitors.
USB Type-C is a physical connector shape; signal capabilities depend on the underlying host controller protocols.
2
Evaluate required specifications for USB-C video passthrough.
Video output over USB Type-C requires DisplayPort Alternate Mode (Alt Mode) or Thunderbolt protocol support built into the host port.
Without Alternate Mode or Thunderbolt support, a USB-C port only carries standard USB data signals and power delivery.
