One grey and two light-blue thermal pads remained on the weight – so it also acts as a heatsink too. A large metal weight (432g) separates from the main PCB with 3 M2.5×4 screws. Note the perforations allowing passive airflow. The Bottom plastic shell can then be freed. It houses the on/off switch and a status LED. The small circuit board is held in place with one M2.5×3 screw. The cable can be freed by gently prying with a flathead screwdriver. The top plastic shell has a small circuit board attached with a 4-wire ribbon cable. Loosening 4 M2.5×4 screws allows splitting the plastic shell in two. The cable and rubber bit weigh 37g together. The USB-C cable is a standard replacement part from HP with a removable rubber strain-relief. Two M2.5×4 screws hold in a small plastic retainer for the USB-C cable. Teardown A single M2.5×4 Philips (+) head screw and two plastic tabs hold the bottom plastic panel in place. The bottom of the dock has a port for the power supply barrel connector and a “sign-of-life” LED which turns on when the power supply is connected and working.

The PSU spec is 120W (19.5V 6.15A) and measures 140mm x 70mm x 25mm. The PSU weighs 505g including the detachable 2m 3-prong AC/Mains cable and integrated 2m long DC cable. Physical characteristics The Dock weighs 688g with the attached 1m long USB-C cable and measures 122mm x 122mm x 45mm. The downstream USB-C port provides 10-15W charging (5V 3A) – in my case the measured voltage was closer to 4.6V but still within spec. For best results, ensure the dock’s firmware is updatedĪlthough 100W PD charging is claimed by HP, I found the dock maxed out at around 90W which is just fine.

Although HP claims dual 4K60 monitor support, many customers have had issues getting this to work correctly with one monitor always getting stuck at 4K30. A handy power switch resides on the top so you don’t have to hunt for the one on your laptop. It weighs about a pound and a half (688 grams) which makes it easy to plug and unplug cables. So its about time I tore it down to find out how it works. I bought my HP G5 Dock over a year ago and with firmware updates it works well.
