HP 13 manual Maximizing battery discharge time, Managing low battery levels

Page 57

The battery charges whether the computer is off or in use, but it charges faster when the computer is off.

Charging may take longer if a battery is new, has been unused for 2 weeks or more, or is much warmer or cooler than room temperature.

To prolong battery life and optimize the accuracy of battery charge displays, follow these recommendations:

●If you are charging a new battery, charge it fully before turning on the computer.

●Charge the battery until the battery light turns white.

NOTE: If the computer is on while the battery is charging, the battery meter in the notification area may show 100 percent charge before the battery is fully charged.

●Allow the battery to discharge below 5 percent of a full charge through normal use before charging it.

●If the battery has been unused for one month or more, calibrate the battery instead of simply charging it.

The battery light on the computer displays the following charge status:

●Off: The computer is running on battery power.

●Blinking amber: The battery has reached a low battery level, a critical battery level, or there is a battery error.

●Amber: The battery is charging.

●White: The computer is connected to external power and the battery is fully charged.

Maximizing battery discharge time

Battery discharge time varies depending on the features you use while on battery power. Maximum discharge time gradually shortens, as the battery storage capacity naturally degrades.

Tips for maximizing battery discharge time:

●Lower the brightness on the display.

●Check the Power saver setting in Power Options.

●Remove the battery from the computer when it is not being used or charged.

●Store the battery in a cool, dry location.

Managing low battery levels

The information in this section describes the alerts and system responses set at the factory. Some low- battery alerts and system responses can be changed using Power Options in Windows Control Panel. Preferences set using Power Options do not affect lights.

Identifying low battery levels

When a battery that is the sole power source for the computer reaches a low or critical battery level, the battery meter icon in the notification area shows a low or critical battery notification.
