We have been running the Optiplex 9010's and 9020's for a few years now and they have been great machines for us. Recently we got a batch of 100 9030's and have deployed them across 8 of our locations. Every night at 9pm we have our power management software shut down all the PCs. With these 9030s we are now seeing an intermittent issue where some of them will go into a state where the power button blinks 3 times in Amber color and the unit will not turn on using the power button or with WOL. The one and only way to get it to come back up is by pulling the power cord for 5+ seconds and plugging it back in.
We have had the motherboard changed on a few of them and that did not resolve the issue either. It also seems to be something that happens later on after the power down has occurred, we can issue the power down a hundred times and it works just fine to power back up, but in the cases where the machine has sat all night is when this happens. We have installed dedicated UPS's on these to try it also and then also took them off the power management software and then shut them down with a remote batch script (Shutdown -r) and they intermittently do it with that also.
The techs that get dispatched this last round blamed our software, but honestly then why is the 9010's and 9020's still doing this without flaw? I don't really know where to go from here. All Sleep/Hibernate settings are disabled in the OS and BIOS, all drivers and BIOS are up to date. I wish we just had 9020's at this point cause they all worked flawlessly.
