P52 won't wake up the monitors connected to Thunderbolt 3 Dock Workstation

2019-10-05, 11:06 AM

I have a P52 and a Lenovo Thunderbolt 3 Dock Workstation Gen2

 

On the dock I have 2 Dell U2415 connected via a DisplayPort cable and a microsoft wired keyboard.

 

When I lock the computer, the monitors turn off after a few seconds. Usually any key press or mouse move wakes up the monitors so I can login to Windows 10.

 

The problem I have is that since the last firmware update 3.1.64, the screens don't always wake up when I press a key. A workaround to nudge the screens to wake up is to switch off one monitor, then switch it back on when the other screen wakes up. Another workaround is to press the dock button which puts the computer to sleep, then wake it up after a few seconds. Clearly both workarounds are not ideal and I would like this problem fixed.

 

Note that I had the same problem when I bought the dock with the original dock firmware 3.1.53 and the problem was solved when I upgraded to version 3.1.61. 

 

I have tried installing firmware 3.1.61 as I had the files around but the installer will not let me downgrade.

 

Is there a way to force a downgrade to version 3.1.61 or is there another way to fix this problem?

 

Thanks

Did you solve your issue with the monitors not waking up? I have this problem!

 

I have a P53 and the Thunderbolt 3 Dock Workstation.

 

I tried all of the different firmware upgrade tools, to see if one of them would recognize the dock.

 

Any direct links would be much appreciated.

Did I solve the issue? Well.... Yes and No...

 

First, let me elaborate on the the No part:

Connecting monitors via DisplayPort (both Daisy Chained and Not) still experiences the non waking up issue with the latest firmware v 3.1.61 released in Aug 2019

 

For me, the screens usually wake up if it has not been long since they slept. So when I leave the computer on overnight, they typically won't wake up and I have to switch one monitor off and on to nudge them to wake up. 

 

I noticed that Lenovo stopped distributing all firmware for this dock so if you are on a version earlier than 3.1.53 I can probably upload them somewhere for you as I have versions 3.1.53 (which works well for me) and 3.1.61 (which does not work well)

 

As for the Yes Part:

I connected the monitors through HDMI and they always wake up. Annoyingly they wake up, go black for a second or two and then start working properly so I guess I can live with that.

 

I just noticed in thinkvantage that there are some new thunderbolt drivers so will install those when I get a chance.

Re: P52 won't wake up the monitors connected to Thunderbolt 3 Dock Workstation

Hello

 

I seem to have a problem on my P53 laptop, as the external displays, connected on the two HDMI ports on the Lenovo TP Thunderbolt 3 Workstation Dock(Product nr.: 40AN0230EU), they just randomly turn on on the first try. If they not turn on, on the first try, I have to put it back to sleep and then awake again at once. I always use the power button on the dock.

So where can I see what firmware version I have for my Thunderbolt 3 Workstation Dock. I se that I have controller driver version 1.41.648.4.

I've also search on Lonovo's site to find a download, but can only find this site: https://pcsupport.lenovo.com/us/en/products/accessory/docks/thunderbolt-3-workstation-dock/40an/down... but I can not see the workstation dock listed, just the Thunderbolt 3 dock, but maybe that cover's both? The version listed is: V1.0.0.20 of 07 Aug 2019.
 
I'm also very confused about what dock I really have, is it the:  ThinkPad Thunderbolt 3 Workstation Dock, ThinkPad Thunderbolt 3 Dock Gen 2 or the ThinkPad Thunderbolt 3 Workstation Dock Gen 2 , or are they all the same as they seem to use the same driver if you look at this site:  https://pcsupport.lenovo.com/us/en/downloads/DS505148  , here the latest driver version are : V10015 of 23 Sep 2019. It's also odd that the Sep version(10015) has a lover number that the Aug version(10020)?

 

 

I'm also very confused as if the terms firmware and driver's are used correctly, and are there really 3 different driver's for one dock, here: control driver, dock driver and firmware?
 
Regards
Terje

I think there's a couple of drivers involved. Firmware, Thunderbolt, Dock Drivers etc. There is definitely a firmware driver that has been pulled for an unknown reason from the website by lenovo. There used to be a link on the dock's website but that has been removed. I have 2 versions of the firmware drivers downloaded but I don't know how to get them to you.

The only way I know is to use the firmware update utility which will tell you what the current version is and whether you can upgrade it.
