Monitors, network, and charging through one cable — power delivery, DisplayPort alt-mode, and driver order.

1. Confirm the port does what you assume

Not every USB-C port carries video or 65W+ charging — check for the DisplayPort or battery icon next to it. Plugging a full dock into a data-only port explains most 'dock is dead' cases instantly.

2. Power-cycle the dock itself

Unplug the dock's power brick for 30 seconds (not just the laptop cable). Docks crash internally and hold the failure until their own power clears — this fixes the majority of partial-failure states.

3. Update in this order: BIOS, Thunderbolt, dock firmware

Laptop BIOS first, then Thunderbolt drivers, then the dock maker's firmware utility. Out-of-order updates cause the classic 'charges but no display' split-brain.

Guide FAQ

Different USB-C capabilities or driver versions. Match the BIOS/Thunderbolt updates first — identical software usually ends the mystery.

For one monitor and charging, decent ones are fine. Dual 4K, Ethernet reliability, and longevity favor business docks — we spec them by actual port needs.
