HELP! Thinkpad Ultra Dock not activating external monitors - T490 laptop Thinkpad

2019-09-26, 0:50 AM

Hi all,

 

I purchased both a T490 and an ultra docking station. Both worked for about a month, then the dock (i think) abruptly stopped working. I plug the laptop into the dock, and neither monitor turns on. The external mouse and keyboard still work. I've tried everything I could find on the forum, but all the drivers and firmware are already installed (from what I have seen). 

 

Please help, I have tons of work coming up very soon and I am severely limited with this tiny screen.

 

Thanks in advance for your help.

Hi Refrigerator! Welcome to our forums community. Have you tried connecting the external monitor directly to the laptop's USB-C or HDMI port? Have you tried installing the firmware of the docking station? If not, you can get it here: https://pcsupport.lenovo.com/us/en/products/accessory/docks/thinkpad-ultra-docking-station/downloads/driver-list/component?name=Advanced%20Firmware.

Hi Jwes,

 

Yes I have tried attaching the HDMI directly to the laptop. This works perfectly fine. I've also installed the latest firmware (thanks for your link), yet my monitors still do not activate when the laptop is plugged into the dock. I submitted a ticket with Lenovo, and they sent me a new dock. This new dock still doesn't work, even with the new firmware installed.

Did this issue ever get resolved. I have the same issue. My docking station stopped working a few works ago, it works with another laptop and also I am able to connect directly to the monitors just not through the dock, the keyboard and mouse work fine.

Changed the Power Cable to my Docking station adaptor and it now works. 

Apparently the power docking station wasn't getting sufficient power. only power to charge the laptop and not enough to activate the peripherals
