Dell T1600 Wake On LAN

September 21, 2012 Leave a comment

At the organization that I work at, we have over a hundred Dells deployed in open labs and classrooms. Sometimes students and professors turn off the computers when they are finished using them which prevents us from sometimes sending out updates, patches, and packages to them. We recently enabled wake on lan on all these machines however, a few machines, specifically Dell T1600 were not listening to the wake on lan packets that were being sent to them. After investigating the matter in the BIOS, it turns out that Dell T1600 and possibly newer models have a feature called “Deep Sleep” which comes enabled by default. In order for the network card to receive the wake on lan packet and wake up the computer, this setting must be set to disabled. Other manufacturers may have similar settings.
