Surface Dock Keeps Disconnecting Intermittently

I have an update on my particulr issue. 

1. Removing Anker usb c to hdmi adapter from dock 2 got rid of “USB power may not be enough...” message. 
2. I have a few razer products, and was running Synapse 2.0 and 3.0 on my Surface Book 3. Uninstalling all Razer related software got rid of all random disconnects. 

Its been hours. Not one disconnect

I habe a 4k 60hz display as well as 34” uwide panel at 2560x1080. 

To test a new found stabilty, i tried running a 4 k movie over docks network jack, and ran cpu stress test at the same time. 

did it for about an hour. 100 CPU utilization. No issues. 

Do any of you run Logitech or Razer software on affected systems?

I also did a quick search, and looks like Razer Synapse has caused identical issue on laptops other than Surface. Lenovo, dell, etc. 

Hope this can help someome

Hi Everyone, 

this doesn't seem to be an issue just for MS dock.  I have a Plugable Dock- that has the exact same issue.  In my opinion it's the laptop's power management that's at fault here. if I don't do any intensive work, then I don't' get these resets.  the resets get specially bad when I have multiple chrome tabs open.

I started deploying the Surface line as an IT Administrator and I have seen this on EVERY dock I've deployed (all first gen, glad someone else tried the 2nd gen on this post cause that was my next step and happy I didn't waste the money since it didn't resolve the issue). Doesn't matter if it's a Surface Pro (Gen 4-7), Surface Laptop (1 and 2), or Surface Book (1 and 2). Ethernet is one that goes out on most often. The screen flickering periodically is another. I seem to get mine working okay as long as I leave the Surface Book open. If I close the lid, it disconnects and reconnects about every five seconds. When it does, the computer swaps from Ethernet to Wi-Fi, peripherals shutdown, audio moves from the dock to the Book. When it reconnects, Ethernet can be disabled for DAYS before it works again no matter how many power cycles on the dock and Book and the audio/mouse/keyboard keep jumping from the externals to the Book and back. Rather annoying when you're trying to attend a webinar or virtual conference and audio keeps dropping in and out and with the network swapping, having to leave and rejoin meetings because "Your network quality is poor".

I've updated the dock firmware, disconnected all peripherals and power cable from the dock to do a power drain, I've swapped the dock for spares in inventory, I've run every Windows update, cleaned the port with a soft brush, blown out the port with compressed air, changed the direction of the plug, and this thing still doesn't behave. One deployment is only a month into its usable life and screens flicker anywhere from 2-3 times per day and 20+ times per day. I've spent over $20,000 on these setups over the last couple of years and I'll be switching back to Dell if Microsoft can't get this figured out. There are WAY too many blogs along with numerous "Microsoft Answers" docs all reporting various issues with the dock. I can't believe Microsoft hasn't made it a top priority to resolve all of these issues.

It wont help. Believe me, I tried!

Same issue here.

Just got a brand new Surface Book 3 15 and Surface Dock 2. USB devices keep disconnecting. I used an external powered hub as well to make sure its not power related issue. 

Nothing helps. Updates. Multiple Surface Book 3 15s. Same ****.

I run my own IT business, and need to use Windows for work, as well as some light gaming.

I also have their horrible Surface Headphones 2 that keep bugging out, disconnecting etc.

There is a reason why MacBook 16 costs what it costs. I have a 5 year old MacBook Pro 15 that hasnt giving me a single problem  in 5 years. 

Microsoft does NOT make quality products. Garbage.
