In this section, we deal with the three LEDs along the top edge on the exterior of the laptop.
(Figure.1 External LEDs)
| 1 | Power LED - Indicates the Power Status | 2 | Hard drive Activity LED - Turns white when the laptop reads or writes to the hard drive. |

The Power LED indicates the power status as follows:
| Power State | LED Behavior |
