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 ( On ). 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.

1Click Start, point to Settings, and then click Control Panel.

2Double-click the Power Saver icon.

3Choose 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.
