On the left side of this screen click on "Choose when to turn off display" or just click the "Change plan settings" link next to the plan you are using.ģ. Go to "Control Panel" and then into "Power Options".Ģ. You say you were int he power settings, but did you check the settings for when the display should turn off and also the brightness settings?ġ. I have had this laptop replaced with an exact replica by my company as well and the exact same thing is happening to the second laptop as well. The action settings for the power and sleep buttons has been set to never as well as other options to test, same with on shut lid action to never, etc. The laptop power and sleep settings have been changed numerous times to various options to see if this makes a difference as well. If I shut the lid and reopen it the screen comes on for a few seconds and then goes black again. When this issue does happen, the laptop is still on, the keyboard lights are on as does the Capslock key light when I press it too. I have tried numerous drivers from the Dell and Intel site and the only time this issue does not occur is when using the Microsoft Basic Driver. I have two external monitors that work fine with the power to the laptop plugged in and unplugged. After some recent Windows or Dell updates, I don't know which my laptop screen goes black when I unplug the power.
