content: That port is designed to work with the Lenovo docking stations/port replicators. They typically come with a "split" cable that plugs into that port and the power socket.Perhaps the cable you have isn't the genuine cable? Or it's faulty?

content: If you are just using a straight USB C dock, not one that requires the hybrid connector, then the problem is likely that you have the wrong cable.Unfortunately, USB-C cables are _not_ interchangable, and unlike USB 3.0+ type-A cables, they are not typically externally marked.The basic USB-C cable is USB 2.0 only and can support up to 3 amps at 20 volts. All USB type C to type C cables must be able to handle this. Anything cable that exceeds that needs a electronic ID chip in the cable to tell the host what the cable capabilities are. This includes USB 3.x superspeed (with 1 or 2 lanes at 5 or 10 Gb/s each), alternate modes like thunderbolt, and 5 amp/100W charging capacity.Many docking stations have captive cables to get around this problem. Alternately cables confirming to and marked as thunderbolt should usually work.

content: You have to pick the right version of Type C cable.No, you can't see which one you have on the outside of the cable.

content: Quote from: Ritchievalens on October 01, 2024, 08:47:04 pmThe genuine Lenovo split cables are joined together with magnets, so the laptop end of the cable can be separated.Keep in mind, docking stations are generally designed to work with specific manufacturers/models of machine. While you can mix and match docks from one manufacturer with a laptop from another, it may or may not work (or fully work). For example, the Dell docks tend to work just fine with Apple laptops.You might want to look into "Universal" docks, like the CalDigit, Belkin, Kensington, Sonnet, Ugreen or Anker ones, if you've ruled out the cables and still aren't having any luck.
