NOTE:
When you disconnect AC power, the display brightness is automatically decreased to save
battery life. For information on increasing or decreasing display brightness, refer to
Keyboard and
pointing devices on page 23
.
You can keep a battery in the computer or in storage, depending on how you work. Keeping the
battery in the computer whenever the computer is plugged into AC power charges the battery and
also protects your work in case of a power outage. However, a battery in the computer slowly
discharges when the computer is off and unplugged from external power.
WARNING!
To reduce potential safety issues, use only the battery provided with the computer, a
replacement battery provided by HP, or a compatible battery purchased from HP.
Computer battery life varies, depending on power management settings, programs running on the
computer, display brightness, external devices connected to the computer, and other factors.
