Is there any way to power on Nexus 7 2012 automatically when charging started? I want to use Nexus 7 as a car PC, so I need this feature for energy economy.

PS - my Nexus 7 is rooted and uses CM 10.1

Install Tasker to be able to:

  • Power off tablet when car is off

  • Use command

    fastboot oem off-mode-charge 0

  • To reset to normal, change the 0 to 1

  • Event for Tasker profile : Power

  • How exactly did you do that?

  • @Tardo What part don't you understand? First, is what you want the tablet to do. Second, is the command used to accomplish that task. Third, is how to change it back for normal operation. You should read the Tasker website and the forums related to the app, for in-depth info.

  • I've got it. The command is the task, execute a shell command. But what is the event you're setting as a Profile to identify when the charger is connected?

    @Tardo contact the manufacturer, your tablet might not support fastboot.
