Lenovo Yoga 720 15 inch (Model: 80X700A3PB ) + Lenovo Thunderbolt 3 40AC - my short experience

2019-12-30, 6:58 AM

Sorry for language mistakes.


I have Lenovo Yoga 720 15 inch + gtx 1050 (Model: 80X700A3PB ) windows 10 Home (newest bios, drivers, windows update).

Two weeks ago i bought Lenovo Thunderbolt 3 40AC (price 100 $ with power supply and usb-c cable - second hand, image in attachement).


This is my short two weeks experience with this docking station.



- works well with two monitors 1920x1080 (one connected to display port, one to hdmi on docking station), no lags, problems ect

- all usb sockets in dock work correctly with pendrive

- i connect mouse receiver to docking station (plus two monitors) - no mouse lags ect - mouse work correctly



- dock does not power up laptop (you need to connect the power supply to laptop)

- power button on dock does nothing


Pros/Cons ????:

- i noticed youtube movie acceleration on chrome (every second movie accelerate on left monitor, barely noticed). This is probably not dock station problem becouse on Firefox this problem does not appear.

- it happened to me (one or two times out of many times) when i disconnect and connect usb-c cable from dock , dock was not recognized. Switch off/on dock station helps.
