Hi, got a new X1E with 4K screen. At max brightness, when I plugged the AC adapter to the X1E, the screen became dimmer. When I unplugged it, the screen became brighter. Plugging the AC adapter back to the laptop dimmed the screen again. What is happening? I did not have this issue on my first X1E.

Welcome to the community forums.
It might be the brightness level in power options is set to a lower brightness when the Ac adapter is plugged in. Could you check that?
Press Windows+X to show the menu, and choosePower Options on it. Type power op in the search box on taskbar, and select Power Options in the results. Way 3: Open Power Options in Control Panel.
Let us know if that worked. Matt_lenovo
