Today I was tasked with preparing two new Dell Latitude E6500 laptops for deployment with two administrative employees. Between software installs both laptops went into Sleep Mode. One laptop would not return from sleep mode at all, or at least the display didn’t. The other laptop returned from Sleep Mode, but the wireless network connection never came back.
The problemeturned out to be the Dell ControlPoint software which came installed on the laptops. Though ControlPoint has one or two neat features, I decided to uninstall it from the machines anyway. After all of the ControlPoint applications were removed both laptops returned from Sleep and Standby modes without any issues.
Hopefully this helps somebody! If anyone finds a specific setting within ControlPoint that can be changed to solve the problem please feel free to post it!
