Does this lenovo tb4 dock have realtek 8153 or intel i225 ethernet?

The circuit board appears to have both Realtek 8153 and Intel i225 chips. When connected to a Surface Pro 8 or Surface Laptop Studio, only the Realtek Ethernet device appears in device manager. The Intel i225 is nowhere to be found. Connecting the Dock to other laptops may result in different behavior.

Funciona con lenovo e15?

The item is compatible with the following E15 Lenovo models: E15 G4-21E6 - E15 Gen 4 and E15 G4-21E7 - E15 Gen 4.

My laptop is giving me a charging error when I reboot while connected to the dock. Is this normal?

There could be a few reasons why this is happening. The 1st being a compatibility error, I am sure you checked compatibility before buying. The 2nd is that a driver or utility update is needed, these are free downloads on Lenovo sight. The 3rd being a loose ac connection. The 4th being an internal error with your laptop due to a MS Windows update. If you have an external battery, turn off your system, remove and re-install the external battery. If not, be sure that the update was fully installed. Supported OS:Win10 64 bit, Win 11 64 bit. The last issue would be that you received a non-USA version of 40B00135US. The USA version has the suffix "US" on the part # (suffix with : UK, CN, AS, ect ect are all docks made for a different country). Always be sure to received USA Product, 40B00135US, UPC 195348677271, the original Lenovo USA packaging should be present and it needs to be sealed with the Red Lenovo authenticity seal.

Bueno, bonito y delgado

Funciona muy bien, cumple con lo que dice en las características. Lo he usado en una laptop Asus, en una HP y en una macbook, en todas funciona bien y continua cargando al equipo. Hay que tener en cuenta dos cosas, es de 65w máximo y es de 60 fps máximo.

Fonctionne tel qu'attendu.

C'est une pièce d'équipement qui va assurément sauvegarder les connecteurs de mon tout nouveau portable. Il accompagne un ThinkPad T16. Le Thunderbolt 4 fonctionne parfaitement, donc un seul branchement et tout est présent sans hésitations. Je recommande pour tout produit ThinkPad.
