EliteBook 745 G5 docks: USB-C and mechanical choices without Thunderbolt assumptions

Which dock options should you consider?

For HP EliteBook 745 G5, start with HP USB-C Dock G5 / 5TW10AA for a current exact-listed USB-C desk, or use HP UltraSlim Docking Station / D9Y32AA when reusing the notebook's proprietary mechanical-dock connector. HP also lists USB-C Dock G4 and Thunderbolt Dock G2, but this AMD host has one USB-C DisplayPort Alt Mode port and no documented Thunderbolt. Treat Thunderbolt G2 as a USB-C fallback with the later, lower DP 1.2 limits—one QHD60 or two 1920×1200 screens—not the older model table's conflicting dual-4K row. Connector fit and an exact list do not create Thunderbolt bandwidth.

Connect displays and power

USB-C host cable

Power G5 with its matching 120 W supply and connect its attached 1 m host cable directly to the notebook's single USB-C Alt Mode port.

G5 displays

Use rear DisplayPort or HDMI. Begin with one FHD60 screen and add a second only after the first input, cable and mode are stable.

UltraSlim path

Seat the notebook on the exact UltraSlim mechanical connector, use the dock's DisplayPort outputs and keep that path separate from USB-C diagnosis.

Power

HP lists 45 W and 65 W adapters but qualifies Fast Charge for 65 W. Verify charging in Windows and compare with a 65 W HP adapter if speed matters.

First recovery steps by symptom

Nothing on the dock works

1. Confirm whether the desk uses the USB-C or UltraSlim mechanical path and verify the matching dock supply.
2. For G5, reseat the fixed host cable in the notebook's only USB-C Alt Mode port; for UltraSlim, fully reseat the notebook on the connector.
3. Test the original HP charger and one USB device before adding displays.

USB works but a display is blank

1. Remove extra screens, select the remaining monitor's exact input and begin at 1920×1080 60 Hz.
2. Use one documented rear output with a known-good cable; on Thunderbolt G2 USB-C fallback, do not use the downstream Thunderbolt socket for video.
3. Add a second screen only after the first is stable and keep the later lower DP 1.2 limits.

Charging is slow or absent

1. Check Windows charging state and the exact dock power supply.
2. Reconnect the host or mechanical dock and remove high-draw accessories during the test.
3. Compare against an HP 65 W adapter; 45 W can power listed configurations but does not carry HP's Fast Charge qualification.

Still unknown: HP's 2018 exact-model table conflicts with its later non-Thunderbolt USB-C fallback limits, so the lower later ceiling is used. Current Windows 11 support, BIOS and dock firmware, high-resolution mode, legacy dock feature support, cable and monitor combinations, sleep/wake behavior and physical results remain unknown.
