Acer Iconia A100 - Turning off the blinking home button (light)

Acer Iconia A100 FAQ: How do I turn off the crazy blinking home button/light on the Acer Iconia?

The Iconia home button light blinks when you have a notification you haven't responded to, such as a new email message. To turn off the blinking light, look at the menu bar at the bottom of the screen, and just to the left of the time you'll see an icon indicating that you have some sort of notification. Tap on that icon, delete your notification(s), and the home button will stop blinking.
