title: How to prevent an android device from entering sleep (via adb command shell)
body: <p>I am working on an embedded board with android on it. Unfortunately I cannot use the display as I dont have a supporting display device (LVDS display).</p>
  
  <h2>Problem :</h2>
  
  <p>Everytime i bootup the device, the device goes into sleep after some time.</p>
  
  <pre><code>Restarting tasks ... done.
  PM: suspend exit 1970-01-01 00:35:30.797352016 UTC
  PM: suspend entry 1970-01-01 00:35:30.905410683 UTC

  Suspending console(s) (use no_console_suspend to debug)
  </code></pre>
  
  <p>How can i avoid it from shell prompt? I am able to login to shell through serial port.</p>
  
  <p>I cannot modify the settings as i dont have access to display.</p>
