HP Mini 2102 - Manual (Page 28)

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 power 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 displays charge status:
● Off: The computer is running on battery power.
● Blinking white: The battery has reached a low battery level, a critical battery level, or there is a
battery error.
● Amber: A 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:
● Decrease the brightness on the display.
● 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
The computer takes the following actions for a critical battery level:
● If Hibernation is enabled and the computer is on or in the Standby state, the computer initiates
Hibernation.
● If Hibernation is disabled and the computer is on or in the Standby state, the computer remains
briefly in the Standby state, and then shuts down and loses any unsaved information.
