title: Android PowerManager and Wakelock, help me understand
body: <p>so I am looking into PowerManager to prevent phone from going to sleep.</p>
  
  <p>Two questions:</p>
  
  <p>1) My phone is currently set to turn the display off after X seconds, will the PowerManager.Wakelock functions override this?</p>
  
  <p>2) My phone has a top button which can be used to turn off the display, or shut the phone off. Will PowerManager.WakeLock override this functionality as well?</p>
  
  <p>insight appreciated</p>
