| − | APM (Advanced Power Management) is a standard in power management developed by Intel and Microsoft, which allows the operating system to control the amount of power sent to devices. Select EMAC products allow for APM Sleep, a command that puts the device into a lower power "deep sleep" state and minimizes the device's power consumption. <br>
| |
| − | <br>
| |
| − | From the command line, use command:
| |
| − | <syntaxhighlight lang="text">apmsleep +[hh]:[mm]</syntaxhighlight>
| |
| − | or
| |
| − | <syntaxhighlight lang="text">apmsleep [hh]:[mm]</syntaxhighlight>
| |
| − | <br>
| |
| − | where hh is hours and mm is minutes, to suspend for hh:mm amount of time <br>
| |
| − | Alternatively the + can be left off to specify a time when the device would awaken. "apmsleep 08:00" would suspend until 8am
| |
| − | <br>
| |

| |
| − | After the given time, the device will resume normal operation and power consumption.

| − | The SoM-iMX6U was designed with APM Sleep in mind, and when issued the command, the device current drops from typical current of 160mA to minimal current of 3.5mA.<br>APM Sleep also sends specified signals to the carrier board to disable systems to further save power. <br><br>The DEV-IOT6U Development Kit (SoM-112ES Carrier Board + SoM-iMX6U) runs at a typical current of 390mA. When APM Sleep is activated, the kit can reach to a minimal current draw of 70.8mA, and with some modifications to APM Sleep to further disable systems on the carrier, the kit can reach a minimal current draw of __.
