Set Alarm to Automatically Power On Linux Computer using the rtcwake Command
It’s no secret that you can make your computer “sleep” to considerably save energy or battery on laptops. A battery-powered device can spend many days in standby mode. The power draw in this state is incredibly low.
You can wake your computer at any time by pressing the power button or a key on your keyboard. But what if you want it to automatically wake up at a certain time? This can help you automate certain tasks – for example, to download something at 4AM when Internet speed may be much higher. With a bit of command-line magic, you can schedule your device to wake up, take some action and then go back to sleep again.
Besides waking up from standby, you may find it even more useful to completely shut down your computer and power on at certain times. Hibernation is also supported, but Linux systems that use proprietary drivers don’t always wake from hibernation properly.
The guide below includes two useful tests to see if your Linux OS will support this.
