First into the CMOS settings of the main interface, select [Power MANAGEMENT Setup], and then select [PWR Lost Resume State], this item has three options.
Select the [Keep off] entry, the computer does not start automatically when you call after a power outage.
SELECT [Turn on], the computer will start automatically when you call again after a power outage.
Selected [Last state], then on behalf of the power outage after the call, the computer back to the computer before the power failure. If the computer is in the power-on state before the power off, then the call will automatically boot. Before the power off is in the shutdown state, then the computer will not automatically boot after the call.
Look after the method is very simple, I will restart the server [Del] into the CMOS settings, but into [power MANAGEMENT Setup] unexpectedly did not say [PWR Lost Resume State], continue to search online, and found that [Pwron after Pwr-fail] This option, finally found in the [Integrated peripherals] option, has two selected on (turned on) and off (turn off automatic boot), set to On, reboot, power off and power test after the success.
When you set up a third server, there is no [Pwron after Pwr-fail] when you enter [PWR Lost Resume State], but there is an [AC back function], which means this function, there are three options, full- On and memory and Soft-off, set to full-on, power off and then power test successfully.
The options for different motherboards and CMOS models are different, but I think they are not too much, generally [power MANAGEMENT SETUP] and [integrated peripherals] these two options.
