Thanks for reaching out to us on HP Support Forums. 🙂 I came across your post and would like to help.
I understand that you have an HP Notebook x2 - 10-p001nh and would like to know the keyboard can be charged and how to connect it to the device via Bluetooth.
Please follow the below steps to configure the Bluetooth connection:
NOTE: The Keyboard works when physically the screen is connected to it. When screen should lock in to the keyboard to make it work. However, otherwise to connect a Bluetooth device please follow the below steps: (Alternate link to setup bluetooth in Windows 10 click here).
The right side of the laptop has the USB type C power port and is used to connect a USB device with a Type-C connector to an AC adapter to provide power to the computer and allows data transfer. When the charging happens, it charges the 2 cell battery in the laptop.
