How do I adjust the brightness of the PCs in the library?
There are a few different makes of PC in the library. Some of them will have brightness control buttons on the edge of the screen, either at the bottom or the left hand-side.
Once you are logged in to a PC you can also access the brightness controls on the Action Centre icon at the bottom right-hand side of the desktop (highlighted with a red box in the image below):
You can adjust the brightness using the bar with the sun symbol next to it, or click on the option for 'Night light' which will dim the screen.
