I have a new Dell Latitude Laptop which seems to be randomly dimming the display depending on the apps I open...
It brightens when excel is opened and dims when it closes, as if to be adjusting or calibrating the brightness automatically. this is the case with a couple of programs
what I want to know:
Is this normal or is there a problem with my driver, I reinstalled it with Windows 8.1 and used the driver disk to recover all the drivers, it then installed an additional driver for Nvidia later on.
How do I stop the display from behaving like this? I am conscious of the power this will drain from the machines battery when running off the battery itself.
what I have done:
I have adjusted the power management settings in the control panel so that it wont dim the display for 5 minutes. (the display changes without letting 5 minutes elapse)
I have tried looking for the Dell Power Management tool quoted on a forum I found but this does not seem to be installed so I can not disable it that way.
the only tool I have found that causes this activity on the web is Automatic brightness but this is not set up and I can not find it in the settings.
