If you are experiencing a 30-second delay after connecting your thin keyboard/ mobility base on an XPS12-9250 or Latitude 12-7275, try these steps to update the firmware.
After connecting your XPS 12-9250 or Latitude 12-7275 system tablet to the mobility base/thin keyboard, your keyboard and touchpad may not function for the first 30 seconds. Once connected for 30 seconds, the keyboard and touchpad function normally. This delay is the result of a mismatch between the system BIOS and keyboard. Follow the process below to update your firmware.

You can resolve this issue by updating the mobility base or thin keyboard firmware from the Dell Support website.
After the firmware is installed, the keyboard/touchpad should activate after 3 seconds. The backlight on the mobility base will illuminate when it is active.
