Question about Lenovo V15 Gen 4
Thanks for the quick reply, my problem is that the docking station has already worked with 2 external screens, mouse and keyboard and after my wife's notebook (Dell) was connected to the same docking station on the Lenovo nothing works via the docking station, no power consumption, no screens, no mouse and keyboard, what could be the reason?
The most common problem with Lenovo notebooks after using a third-party device is a failed USB-C function (e.g. Power Delivery/DisplayPort Alt Mode). This can be the cause:
- USB-C port on the Lenovo is electronically "crashed" → device disconnects power/video until a complete reset is performed.
- Dock has "swallowed" itself → Firmware reset necessary.
- Dell has forced a different power profile → Lenovo then refuses to negotiate.
Quick test:
- Switch off Lenovo completely → hold power button for 30 sec.
- Disconnect dock from power, wait 1 minute.
- First connect the dock to the mains, then connect it to the Lenovo via USB-C only.
If there is still no power consumption, the USB-C port of the Lenovo is most likely defective or overload-protected. Unfortunately, this happens quite often.
