ThinkCentre m93z/m9350z screen brightness is not adjustable

Failure phenomenon:

The New thinkcentre m9350z may cause problems with screen brightness that cannot be adjusted.

Reason Analysis:

Because the host has a power management software pre-installed, power management software support through the host of the photosensitive probe automatically adjust the screen brightness to achieve energy-saving functions, such as the need to manually adjust the brightness, turn off this function.

Solution:

Closing the Photoconductor probe in the Power management software rollup resolves this problem by following these steps:

1. Open the Power management software, click the upper right corner switch to advanced version, and then select the Global Power Settings tab;

2. Expand the sensor support, remove the inside "open use built-in light sensor for dynamic brightness control" checkbox;

3. Apply settings.
