Hi Stoke,
I’m having the same problem with the stock FW16-charger. When going through my dock, the CPU frequency goes down to ~0.5 GHz and the system is basically useless. I opened a ticket describing the problem which got escalated two days ago. I didn’t hear back about it yet.
Just tried out the setup with the FW13-charger after reading your post and it works perfectly. Thanks for the idea. Apparently, it has something to do woth the FW16-charger.

Glad it’s not just me!
I opened a ticket as well, but I think they just chocked it up to the dock, but that conclusion isn’t consistent with my findings.
I also ordered a 165W PD 3.1 Charger to see if it has something to do with the higher wattages. Will check this weekend
I didn’t think to check frequency, but that checks out, I’m getting the exact same behaviour. Where usage usage increase in the histogram is where I plugged in my dock using the fw16 charger.
I’m not entirely sure it’s the charger, it’s possible it’s the laptop firmware/onboard pd controller. I tested the fw16 charger and my dock on my old laptop, and had no issues.
I did find this in the logs; I ran dmesg while disconnecting/connecting the charger.
Here is the output when connecting the 180w directly to laptop (port 1)

Here is the output when connecting the 180w charger to the usb hub which is connected to port 4.

Just to confirm your issue:
- FW16 charger through the PD MFD hub you are using has this issue.
- FW13 charger through the PD MFD hub you are using does not have this issue.
both chargers attached directly do not have this issue.
I suspect your FW16 charger or hub is triggering a power renegotiation over and over. Which is something we will need to try and root cause to investigate further.
On my end, correct. No issue plugged directly to laptop, but issues when plugged in through the dock. I’m not the one with the fw13 charger though. I have tried a 65w and 45w charger, and they both work great with the dock. Will try 100w and 165w this weekend.
I’ve also tried on a cheap, no-name dock, and had the exact same behavour.
Would be great if you would share which powerbank model it is which is working so well with the FW 16.
Thx!

Of course my bad I forgot to I include the model.
It’s this one :

I tried out a 140W 3.1 PD charger today, and had some interesting results.
This is the charger and I’m testing on fully updated Fedora 39. Used FW EPR cable.
Plugged directly into the laptop, the charger would not provide “charge” (I was seeing about 5w discharge with powertop which is less then it was when unplugged). I tried multiple ports on both sides of the laptop.
With this charger plugged into the dock, I saw the same behaviour with the FW 180w charger. 0.5 CPU freq, stuttering, increased CPU utilization.
Updated to include:
I just tried this 100w Anker charger with my laptop/dock, and have noticed no issues.
My understanding of the power button on the dock is that it’s proprietary and/or only works on Dell devices.
I’ve plugged multiple machines over the years into my Dell WD19TB and only my dell laptop will recognize and perform the power on/off behavior. To be clear, the power button doesn’t work on my FW16 either.
Agree on that.
I however have another problem I can’t understand.
- I configure my session to use the external monitor.
- I configure the FW16 BIOS to power on the AC on is provided
When the laptop powers on:
- I see the screen asking my for the password to unlock the encrypted drive fine.
- I even see the logging screen (sddm) fine on my external screen.
However, as soon as I log in, the external screen turns dark.
I have to unplug the USB-C from my dock, and re-plug it in for the external screen to show the session.
Anyone knows what is going one?
Using the Display-port adapter on the dock, and usb-c is plugged to position 1.
I tested two Anker hubs, aiming for the holy grail of 3 external monitors, ethernet, and USB-PD with only one USB cable.
Both the Anker 555 8-in-1 and this Anker 14-in-1 seemed to go into a perpetual USB-PD renegotiation loop when I connected them to the Framework 180W USB-PD adapter. Connected to a different 65W adapter, both hubs seemed to work fine. I don’t have a 100W adapter to test with.
I have the same problem with my another fedora laptop and the wd19tb. What works for me is reduced the framerate from 60 to 30hz on a 4k monitor or swapping the dp cable to a hdmi cable. I dont why, but that resolves the black monitor output for me
I am pleasantly surprised at how well my Anker 13 in 1 dock is working, has Audio, 2 HDMI, 1 DP, Ethernet, micro SD, 2 USB-C, 3 USB-A, all powered, all compatible with FW-16, currently half price. I am not using several of the ports, (HDMI and DP aren’t needed) but it frees up almost everything on the FW16. When travelling, I will be able to just pull one USB-C, take the power supply, and go.
Do you have a product Name? Mostly a three digit number
want to add quickly that dbb9003l1 doesn’t work. I happen to have this old model which worked fine for FW 13 but is too low in power delivery for FW16, so it works as a display extention but doesn’t charge the FW16 while plugged in.
Using a single cable from both my FW13 and FW16 to the CalDigit Thunderbolt Station 3 Plus I am successfully getting video, power and data.
I’s using the ThinkPad Universal Thunderbolt 4 Dock (40B00135EU) and it works fine, but i have no discrete GPU
Does anyone have any experience with the Tuxedo Triple Dock on FW16. Since it is specially made for Linux, I am particularly interested if it works with a Linux Distro installed. So far, I have not found a Dock where audio works properly and that is absolutely stable when plugged in.
Yes, I got the same one. Seems to work great, although it was a bit picky on which monitor should be plugged in which port. Found a working combination though.
The Dell WD22TB4 works nearly flawlessly with the FW16, at least on my set up:
- Ethernet
- Some USB devices
- A 1440@145 display via DP
- A 1080@60 display via HDMI
- Power delivery
No issues with glitchy behaviour that require reconnects and whatnot. However, there are caveats:
- The dock’s power button only works with Dell laptops
- PD over 90W only works with Dell laptops
- The 1440p display goes up to 165Hz, but the display won’t activate at that refresh rate (it does directly plugged into the laptop)
Otherwise, a solid purchase and you can get them really cheap off ebay
