Symptoms
Overview:
When you plug one or two monitors to a docking station while it is connected to a laptop, you may notice that one or more screens go blank when you close the lid. It is possible to still use one or more monitors even though you shut the LCD lid. All that you have to do is to change the setting under Power Options.
Windows 7:
1. Go to Control Panel and select Power Options.
Note: If you do not see this, try changing the Control Panel to "View by: Small icons"
2. On the left side, click "Choose what closing the lid does."
3. Select "Do nothing" from the drop-down menu under "On battery" and "Plugged in."
4. Click Save Changes and you may close the screen after.
