I’ve been working on getting our PCs setup so that i can wake them up to do updates when ever i want. I found the easy setting in the Bios of Remote Wakeup, which has to be enabled. I was having a problem with some of our Dell Optiplex 745’s that they wouldn’t wake even with that setting set. So after some looking around there is another BIOS Setting for Low Power Mode, which is set to on for some reason on the 745s which turns off everything (including the NIC) when the computer is shut down. Once you turn that off, you are able to wake the computers.
This isn’t something that i was about to manually do on 1200 computers, so I downloaded Dell’s Client Configuration Utility which allows you to create .exe’s that deploy BIOS settings and can also be used to do BIOS updates. again, the remote wakeup was easy to find, it was called WakeUp on Lan and i enabled it for all NICs. The Low Power Mode was a bit more hidden. Some searching in the utility turned up a setting labeled LowPowerS5. Since i wanted to turn off Low Power Mode, i set this to disabled. This was not the right setting. For whatever reason, you actually enable LowPowerS5 to turn off Low Power Mode. Below is a screenshot of my two settings:
I Clicked create client package in DCCU and saved the resulting .exe. I then used our BigFix installation to create a Software Deployment Task and sent it to a couple of test computers.
Now i just need to send it out to the other 1197 …
