Monitoring battery power
❖ Green means the battery is fully charged.
❖ Amber means the battery is charging (AC adapter connected).
❖ Flashing amber means the battery charge is low and it is time
to recharge the battery or plug in the AC adapter.
HINT: Be careful not to confuse the battery light ( ) with the
on/off light ( ). When the on/off light flashes amber, it
indicates that the system is suspended (using the Windows
Standby command).
Determining remaining battery power
NOTE: Wait at least 16 seconds after turning on the
computer before trying to monitor the remaining battery
power. The computer needs this time to check the battery’s
remaining capacity and perform its calculations.
1 Click Start, point to Settings, and then click Control Panel.
2 Double-click the Power Saver icon.
3 Choose the Power meter tab to show the current charge state
of the battery.
The value displays as a percentage of remaining battery
charge.
TECHNICAL NOTE: The computer drains battery power faster
at low temperatures. Check your remaining charge frequently
if you’re working in temperatures below 50 degrees
Fahrenheit.
The computer calculates the remaining battery charge based
on your current rate of power use and other factors such as
the age of the battery.
