I have been thoroughly satisfied with my Dell Latitude E6400 except for one large annoyance: it regularly hangs when resuming from sleep mode. It isn’t completely frozen when this happens – some applications will respond to mouse clicks but my web browser, IM, and Skype windows become unresponsive. Eventually things come back to normal but the wait is embarrassing if you’re sitting beside a Mac user.
Fortunately I think I have found a solution.
This week I was finally fed up with the long hangs and did some troubleshooting. I found that killing the DCPSysMgr process would instantly bring things back to normal. DCPSysMgr is part of the Dell ControlPoint System Manager. After uninstalling that application, my computer resumes from sleep almost instantaneously.
