No, this notebook does not have an RJ45 connection

No! Not active.

The HP 255 G10 notebook with the specific specifications (15.60", AMD Ryzen 7 7730U, 16 GB, 512 GB) can be connected to two monitors under certain conditions, but there are some limitations to consider. ### USB-C port limitations - The HP 255 G10 notebook probably only has one USB Type-C port that does not support Alt Mode or Power Delivery, which means that it cannot be used directly for display transfer via USB-C docking station. ### Connection options - To connect two external monitors, you can use the following methods: - Monitor 1: Directly via the HDMI port of the laptop. - Monitor 2: Using a *DisplayLink Certified* USB-A to HDMI adapter. ### Docking station - The HP USB-C Dock G5 may be compatible with USB-C and Thunderbolt™-enabled laptops, but if the notebook's USB-C port does not support Alt Mode, the docking station will not be able to recognise the monitors via the USB-C port. To summarise: It is possible to connect two monitors, but not directly via the HP USB-C Dock G5 if the notebook's USB-C port does not support Alt Mode. Instead, you should use the methods mentioned above.

I've never used up the battery completely, but after three or four hours, there was still a good 50% left.
