I have been trying to test my laptop's battery recently but I have found an issue where the battery usage breakdown in the settings app is incomplete. Screenshots on the internet show percentage values for "System", "Display" and "WiFi" but these do not exist on my machine. I have no memory of these statistics ever existing on my laptop and I only found out about them by seeing screenshots of other people's settings apps.
Below is an image of a screenshot from the internet where the readouts are visible and a screenshot from my computer where they do not exist.
The computer is a new Lenovo ThinkPad with the original battery and Windows 10 Home 1607 (64 bit).
