GETTING STARTED
Battery/AC Adapter Status Indicator
The Battery/AC Adapter status indicator tells you whether your notebook is operating from the
AC Adapter or the Lithium-Ion battery, and whether the Lithium-Ion battery is charging or not.
• The light illuminates when the computer is operating from the AC Adapter.
• If you are charging your battery, the indicator remains on even if your notebook is shut off.
• If there is no battery activity, the power adapter is not connected, or the power switch is Off,
the indicator will also be off.
• Batteries subjected to shocks, vibrations or extreme temperatures can be permanently damaged.
Hard Disk Drive (HDD) Activity Indicator
The Hard Disk Drive (HDD) Activity indicator tells you whether your internal hard drive is
being accessed and, if so, how fast.
