Device Status Lights
The device status lights located at the front left
of the computer provide information for wireless
communication and keyboard input options.
1. Power light – Turns on when you
turn on the computer, and blinks when the
computer is in a power management
mode.
2. Hard drive activity light – Turns
on when the computer reads or writes
data. A flashing light indicates hard drive
activity.
NOTE: To avoid loss of data, never
turn off the computer while the hard
drive activity light is flashing.
3. Battery status light – Turns on
steadily or blinks to indicate battery
charge status.
