The Battery Pack
Lithium-Ion Battery
Your notebook uses an eight-cell Lithium-Ion battery pack that provides power when you
don’t have access to an AC outlet.
Note: It is necessary that you charge the battery pack for at least 6 hours before using it
for the first time.
Note: In the Standby Suspend mode, a fully charged battery loses its power in roughly
1/2 day or less. When not being used, the battery’s power will deplete in 1-2 months.
Battery Low-Power Warning
1. Low Battery Warning
Your computer’s battery uses power a until a low battery condition occurs when battery
power is reduced to 6%. The red battery status LED indicator blinks and the system beeps
once every 16 seconds or so.
2. Very Low Battery Warning
Very Low battery condition occurs at 3% power remaining. The red battery status LED
indicator blinks and the system beeps at 4-second intervals.
When the notebook warns you of its low battery condition, you will have about 3-5
minutes to save your current work.
Warning: Do not expose battery packs to temperatures below 0 degrees Celsius (32
degrees F) or above 60 degrees C (140F). This may adversely affect the battery pack.
Note: Press Fn+F3 to turn off the battery warning beep.
