Resume by RTC Alarm on Windows 10 Pro.

I would like to have an automated test on powering on and off my PC. Its some stuff i need to do in the office.

First, I have a PC running a windows 10 pro OS. To have it automatically power it off by having a batch file with the shutdown command in it placed in the start up items in the windows. Now, to have the PC to automatically power on, I need to set the Resume by RTC alarm feature in the bios and set the time I want to power on the PC. It works perfectly on Windows 7 but It does not work on the later versions Windows 8.1 and Windows 10.

Can somebody help me with my issue?.

System Information:

OS: Windows 10 Pro x64

MOBO: MSi H97M-E35

Processor: Intel Core i5

Any help would be appreciated.

Your requirement is a little exotic . . .

Here is a method that will work:

Create a scheduled task that will shut down the PC some x seconds after the automatic log on.
Set the BIOS so that it starts a boot-up sequence when power is resumed.
Use an external controller that cycles power with this pattern: 3 minutes on, 1 minute off.

The sequence will then work like so:

The controller applies power.
The BIOS boots up the PC.
The scheduled task shuts down the PC.
The controller turns off the power.
Back to Step 1.

The external controller could be a PLC (Programmable Logic Controller), if you can afford to buy one. If you have the skills to build an electronic circuit yourself then you can get the same functionality with a few chips and a relay.

Schedule boot of your computer with a RTC event (or alarm)

3. BIOS Award - Old BIOS

To enter Award BIOS, press the "DEL" key. Note : To find out which key should be pressed, just look at what is written under the logo of the motherboard at the bottom of the screen.

For example, with this Gigabyte motherboard, the boot menu is accessed by pressing the "F12" key and the BIOS configuration by the "DEL" key.

In the Award BIOS (old BIOS), go to the "Power Management Setup" menu.

Locate the line "Resume by Alarm" and press Enter. Note : If this option isn't present, is that your motherboard doesn't support this feature.

Select Enabled from the list and confirm by pressing "Enter".

Once enabled, the BIOS will change several options for you to say: - The Day : The number of the day from 1 to 31 on which the computer will start automatically or "Everyday" for all days (as shown in the picture). - Hour : 0 to 23 - Minutes : 0 to 59 - Seconds : 0 to 59 (if you want to be very precise;-) )

For example, the screenshot below shows that the computer will automatically start every day (because, day = Everyday) at 10h 15min and 25sec.

Finally press "F10" to save the changes. And answer "Y" when the confirmation message is displayed :

Warning : After several tests, we noticed that the motherboard was not supplied in the same way before starting the computer after turning it off. In fact, when you turn off your computer remains powered devices (hence the light of our keyboard and mouse that remained lit). If you physically disconnect the power from the computer by unplugging the plug and you 2 minutes later, you will see that the devices are not (oddly) more energized until the computer has not been turned on at least once. If you are told this is simply because if you do not let the hip after taking off (the software) on your computer, the computer will not start. Unless you perform a clean boot the computer when you disconnected the plug and when the pc should start automatically. So if you have devices that emit light trying to hide one way or another but do not disconnect the mouse or keyboard because your BIOS might produce the error "Keyboard not found". Which block the startup of the computer screen on the motherboard.
