P72/P1/X1e Problems with 40AN Thunderbolt 3 Docks

2019-03-13, 13:50 PM

ok have have moved (or trying to) from P51 with "old style" dock to the P1 with Thunderbolt 3 dock and there are quite a few issues with the 43AN Thunderbolt 3 docks - listed in different threads here - so I thought I'd add my own and consolidate a bit

 

1. General latency / speed / audio issues with devices on ThunderBolt 3 dock - many people have issues with devices connecting through TB3 - from Audio Pop's to failing video on Web-cams - and for me USB3.0 Logic Analyzer won't run very well  - in short - high speed USB3.0 and above does NOT perform to USB3.0 high speed specs 

 

2. Cables are not long enough between TB3 and computer and limt placement of the dock to the left side (or above/below) the ThinkPad. 

 

3. For me - lots of issues hot-docking / undocking - last time display went into "multi colored" Text mode with all kinds of charecteres from the ANSI being randomly displayed on screen.

 

4. Waking from sleep - Every time my P1 wakes from sleep it is a gamble if all 3 external monitors turn on. 1/2 the time 1 of my screens does not show anything - but Windows still think it is present (the other screen of the same type turns on fine)

 

5. Booting: I can't select external screen as primary/preferential in Bios - it is always grayed out. That means I have to turn on with the P1 open. Since I have 3 external screens - it means my NVIDIA card is ALWAYS active (hybrid graphics only works on Intel card with up to 3 screens total - with total 4 screens the NVIDIA will be active)

 

6. It is complete idiotic to have dual power supplies ? Who ever thought that would be a good idea? 

 

 

So in short and in my oppinion - the TB3 40AN is a complete failure that should NEVER have been put on the market. I hope we can go back to a "normal" docking station in the future. Or at least test the devices before they leave engineeering. Right now I would say the TB3 does not work as advertised - or work very badly.

 

btw both my P1 and Dock has been upgraded with latest firmware. All the above is based on latest firmware. Before latest firmware it was absolutely unusable. 

 

Please feel free to add to this - and please Lenovo - have your engineers look at this and come back with some solutions (even if the solution is a total RECALL of all the 40AN230 / 40AN170 TB docks. I think that is the right thing to do. They need to be re-designed.

And a few more issues

 

7: After sleep or hot-plugging - won't recocnise USB Keyboard and mouse connected to the correct docking USB port. Error: USB Device not recognised. Full reboot required to make them work again (through USB hub - Lenovo Keyboard and 3D Connection wireless mouse) - pulling USB connector(s) in / out does not rectify the issue - so seem like the USB port "dies"

And another issue

 

8. Occasionally the 40AN230 dock will die and reboot? The screens stay connected - but all USB devices gets disconnected. After 20-40 seconds the dock will come online again and then "mount" all USB devices

 

I am amazed that Lenovo has not bothered answering any of the above issues.

 

I'm close to putting up my P1 for sale and going back to my P51. Without a dock working it is almost impossible to work with the P1 - and the other P1 issues are really annoying (overheating / low performance due to temperature throtteling)

Another issue:

 

9. Not only is speed often slow from the 40AN USB3 & USB-C ports - often they fail. I can't import video/pictures through the 40AN USB ports from iPhone, iPad Pro 2018, Osmo Pocket, Nikon Z7 or any other high speed USB3 or better device. Win10 Photo app breaks down after 3-10 pictures. Switch cable to one of the built in USB 3 or USB-C and everything works as expected. I have less issues writing data to the same devices. 

 

 

 

And it really makes mad sad and mad that Lenovo completely ignores the issues.

 

For those interested the ThinkPad 40AN provides 5v 3.0A max for charge of USB devices.

We have pleased to report that we are very satisfied in using our 40AN0230UK ThinkPad Thunderbolt 3 Workstation Dock (Gen 2) the one with 230 W power adapter, which worked well with our X1E1 (X1 Extreme 1st Generation).

Specifically, we could use our dock's USB3 ports to import video/pictures from iPhone, and also external hard drives!

 

Very satisfied with this product; it sure saves me from the hassle of connecting/disconnecting various cables numerous times everyday!

That sounds curious. Which firmware are you using?

 

Could you try and post some speed test/bench marks of real USB3 devices - like SSD hard drives? (CrystalMark ?)

 

My iPhone empties fine when files are few and small.

 

But as soon as I have lots of large files and/or recorded 4k video files - my Dock falls over - and often even resets the TB connection - so everything connected to the dock disconnects and then re-connects once the dock "reboots"

Our X1E1 (X1 Extreme 1st Gen) has BIOS v1.23

 

Our ThinkPad Thunderbolt 3 Gen 2 Docking Station for Workstation (40AN0230UK) is on firmware v3.1.53 (the latest according to Lenovo Vantage for our X1E1).

 

Win 10 (64-bit) OS.

 

Transferring photos from iPhone/Android via USB3 connected to this docking station was fast for small/medium sized files.

 

I've never had any 4k video or 4k photos, so cannot comment on transfer speed for such large files unfortunately.

Hi,

 

3.1.64 is (and was when you wrote) the lastest firmware for the dock. Btw my Lenovo Vantage has never alerted or shown me Dock firmware - could you post a screenshot where you found the Firmware details in Lenovo Vantage?

 

But that has not helped much - it is slightly better. But now I'm getting charge error messages from time to time that my 230w Lenovo charger cant charge... It is not consistant though.

 

But still impossible to have external screen connected and run purely on Intel GPU. The moment you connect external screen the NVIDIA card is enabled - despite documentation says it should be possible otherwise.

And the Saga continues with P1/Thunderbolt Workstation dock.

 

So issues have still not been solve and now.....

 

1. Seems like ThinkPad Workstation Dock (40AN) firmware pages have completely gone missing? All references missing - all seachers leading to "404 pages"

 

2. Now iTunes WILL not start when P1 is plugged in to Thunderbolt dock (only screen/network connected - nothing else)  (v 12.10.2.3 64bit)

 

3. Attaching iPad Pro with USB-C cable via Dock does no longer work at all - Windows/P1 thinks the iPad is an external screen with incorrect display parameters. Works fine through "P1 2nd USB-C" ?????

 

4.Elgato Stream Deck will not wake up from sleep when connected to Dock USB (after computer has gone to sleep) - works fine from P1 direct USB's

 

This is a COMPLETE disaster!
