I have a UD-CAM that works fine with numerous Apple thunderbolt-3 based client laptops that I bring to my workstation to work on. However, they all exhibit the same minor behavior when idle. On a non-regular delay, the laptop will make the “you just plugged in a power adapter” sound. Sometimes it’ll chime 2 times in 5 seconds, sometimes after 30 seconds, sometimes after a few minutes. All while the laptop sits idle and asleep. If I log into the computer, it doesn’t seem to happen. And this does not happen when attached to an Apple power adapter.
It’s happening right now to a MacBook Pro (16-inch, 2019). Does not seem to affect 13" models at all. Is it possible that this dock is not quite up to the task of supplying the full 85W of power?
Plugable-supplied power adapter. Pluggable-supplied USB-C cable. No USB devices, no HDMI displays, no headphones, no LAN cable attached.
