HP ProBook 650 G4 docks: USB-C choices without assuming Thunderbolt

Which dock options should you consider?

For HP ProBook 650 G4, lead with HP USB-C Dock G5 / 5TW10AA: HP's July 2020 list names both the standard and Hex Core variants, and its fixed USB-C host cable can provide up to 100 W to supported HP hosts. Start with one Full HD 60 Hz display on a rear DisplayPort or HDMI socket because HP does not establish this laptop's exact DisplayPort revision or DSC support; the dock's higher multi-4K rows are conditional, not promises for this computer. USB-C Dock G4 / 3FF69AA is an exact-listed standard-model alternative, but its documented host profile tops out at 60 W, so a 65 W or 90 W laptop configuration may charge slowly or need its original adapter. Thunderbolt Dock 120W G2 / 2UK37AA is also manufacturer-listed, but this laptop is documented as USB-C DisplayPort Alt Mode rather than Thunderbolt: use the fallback path and do not use the dock's rear Thunderbolt socket for video. An existing UltraSlim Dock can use the proprietary side connector. Check the service label first, because HP treats the Hex Core family separately in support records.

Connect displays and power

G5 computer cable

Power the G5 with its 120 W supply, then connect its fixed USB-C host cable directly to the laptop USB-C port. The front USB-C socket is for data and up to 15 W accessory power, not a monitor.

Display baseline

Put one known-good FHD60 monitor on a rear DisplayPort or HDMI output and select that input. Add another screen only after confirming the exact laptop configuration and dock mode.

G2 fallback or UltraSlim

For Thunderbolt Dock G2, use the USB-C host lead and rear DisplayPort/USB-C video outputs—not the rear Thunderbolt socket. For UltraSlim, seat the laptop on its side docking connector.

Power

Read the original adapter label: HP lists 45 W, 65 W and 90 W configurations. G5 and G2 state up to 100 W to supported hosts; G4's highest host profile is 60 W. Verify the Windows charging state.

First recovery steps by symptom

Nothing on the dock works

1. Identify the exact dock and connect its matching HP power supply.
2. Reseat the single USB-C host cable or the UltraSlim side-dock connection with no extension or intermediate hub.
3. Test the laptop with its original charger, then prove one USB accessory before reconnecting displays.

USB or Ethernet works but the display is blank

1. Disconnect extra screens and connect one known-good FHD60 monitor to a rear DisplayPort or HDMI output.
2. Select the monitor's exact input; on Thunderbolt Dock G2 fallback, do not use the rear Thunderbolt socket for video.
3. Compare the laptop's direct HDMI or VGA output, then update the exact-model BIOS, graphics components and dock firmware before rebuilding the desk.

Charging is slow or absent

1. Compare the laptop's original 45 W, 65 W or 90 W adapter label with the dock's host-delivery limit.
2. Reseat the direct host connection and temporarily remove high-draw accessories.
3. If the original charger restores charging, keep it attached while checking the dock supply, cable and firmware; this is especially relevant to the G4's 60 W ceiling.

One screen works but the full set does not

1. Return to one FHD60 monitor and confirm it works alone on a rear video output.
2. Add one display at a time without increasing resolution or refresh rate.
3. Treat HP's higher dock display rows as conditional until the exact host DisplayPort revision, DSC support and cable path are established.

Still unknown: The exact unit's standard versus Hex Core support family, original adapter requirement, DisplayPort revision, DSC capability, simultaneous monitor modes, cable capability, current Windows 11 and firmware support, management behavior, sleep/wake reliability and field performance remain unknown. HP's dock tables are manufacturer documentation, not a Connect Your Dock hardware test.
