Heya,

Notebook is about 3 months old, my TB16 dock worked fine since day one but suddenly as of friday a week ago charging no longer works via the TB16 Dock.

• I am running Linux with an option to dual boot into windows.
• Windows behaves the same however
• Same thing happens when in BIOS and just watching the Battery screen
• BIOS will report plugged in and charging but percentage goes down.
• Dock is sometimes detected as 60W (in Bios) first but then switches to 130W quickly - indicates as charging but percentage goes down.
• Tried co-workers TB16 Dock - same thing
• Works fine via barrel plug

What I tried

• Disconnecting the dock for a while
• Booting with/without dock attached
• BIOS battery settings (standard/adaptive/quick charge on/off)
• Holding Dock button for a minute while disconnected from power and notebook
• Checking the plug on the power brick of the docking station - removing and replugging it while dock was running and while it wasn't

As I am running linux by default I am sure that on the day it stopped working I did not do any bios/driver whatever updates.

As it's also not working in Bios it should be OS/driver agnostic.

Any idea what's wrong or what I could do?

The dock works normally apart from that - usb devices and display link monitor are working fine.
