x1 carbon dim on startup, then brightens

i7 4600 cpu - 2560x1444 display

Sometimes I start the machine and the display is dim for a few minutes, then returns to normal brightness.  Brightness setting is at max even when display is dim.  This is with AC power, and power setting is for max brightness.

Hi Feistmann,

Welcome to Lenovo Community Forums!

As per the query we understood that you are facing issue with ‘Dim display on startup’ on your ThinkPad X1 Carbon.

-Open driver settings window (mouse right click on the desktop, -> Graphical Parameters);
- Advanced Mode;
- Menu item Power;
- Power Source -> on battery
- Deselect Display Power Saving Technology and Auto Brightness Control.

Hope this helps.


Best regards.
