I wanted to find a way to power on my computer at 7:30am each morning. This was so that my email and various websites I visit can be updated before I sit down at my computer. With mornings being such a rush, I wanted to use some automation to help me out.

There are normally a number of features in the power management component of the BIOS options, which permit all types of triggers to wake a computer up from hibernation or standby modes. However, if the computer is turned off, these will not work.

One of the triggers allows us to set the computer to launch via the real time clock. We can set how frequently the machine will wake up, or what time of the day we want it too wake up.

Every BIOS is a little different so it is impossible to give specific instructions, but it is not too hard to find. Go into the BIOS and find Power Management. In here, ensure S3 is enabled. There should be an option called “Resume by alarm”, or “Wake-up on RTC”. Once this is enabled, you will be able to set the time you want your computer to turn on. That should be all there is to it.

While I had not seen this feature before, I checked the 3 computers I have access to, to see if they also had this option. These machines are of various ages and they all included this feature. Only one time can be set in the BIOS, so using this method will not work if you want it to turn on in the morning and the afternoon. If you want to do this, you will need to use the task scheduler.
