I have a probook 440 laptop on which I am unable to increase the brightness level by pressing the Fn key and then F10 (increase brightness) button. It just shows me the bar but does not increase it. Other keys when pressed with Fn are working. I tried browsing through the display and power settings on the laptop but did not find the suitable option. Is there any other way I can increase it?
