The options for the different motherboards and CMOS models will vary, but I think it should not be too much, generally in both [POWER MANAGEMENT SETUP] and [Integrated peripherals] options. Here are two types of BIOS setup methods mainly have two kinds of Bios:1) Award BIOS setup method is as follows: first go to the CMOS settings main interface, select [POWER MANAGEMENT Setup], and select [PWR Lost Resume State], There are three options for this item. Select the [Keep OFF] Item, which means the computer does not start automatically after a power outage. SELECT [Turn on] to indicate that the computer will start automatically when a power outage is called. Select the [last state], then on behalf of the power outage after the call, the computer back to the state of the computer before the blackout. If the computer is in the boot state before the power off, then the call will automatically turn on, before the power off is in the shutdown state, then the computer will not automatically boot after the call. 2) The AMI BIOS setup method is as follows: Find the "Restore on AC Power Loss" option, which is to set the motherboard after power on the switch operation. This option has three sub-options, where "Power on" means that it will automatically turn on when the motherboard is powered up. The default "Power Off" option means that the motherboard must be switched on manually, i.e. by pressing the switch button on the chassis, regardless of power-on. As for the "last State" option, it means that if the motherboard is turned on before it is suddenly powered off, it will start automatically after power-up, and if it is properly powered off, it will not start automatically after re-power.
