WARNING!
the external contacts on a battery; or dispose of a battery in fire or water. Do not expose a battery to
temperatures above 60˚C (140˚F). Replace the battery only with a battery approved for this computer.
Refer to the

Replacing the battery

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.
Battery Check notifies you to replace the battery when an internal cell is not charging properly, or when
the battery storage capacity has reached a "weak" condition. A message refers you to the HP Web site
for more information about ordering a replacement battery. If the battery is possibly covered by an HP
warranty, instructions include a warranty ID.
NOTE: To ensure that you always have battery power when you need it, HP recommends purchasing
a new battery when the storage capacity indicator turns green-yellow.

Switching between graphics modes (select models only)

The computer is equipped with switchable graphics and has two modes for processing graphics. When
switching from AC power to battery power, the computer switches from High-performance mode to
Power-saving mode to conserve battery life. Similarly, when switching from battery power to AC power,
the computer switches back to the High-performance mode.
NOTE: In order to optimize computer performance, the system might not allow switching modes, or
prompt you to switch modes. It might be necessary to close all programs before switching.
NOTE: HDMI only works in the High-performance mode. HDMI cannot be used in Power-saving mode.
When switching between AC and battery power, you are notified that the computer is about to switch
graphics modes. If you prefer, choose to continue using the same graphics mode. While the computer
switches modes, the screen goes blank for a few seconds. When the switch is complete, a notification
appears in the notification area, and the screen image reappears.
NOTE: When select computer models are in slate mode, the screen orientations are reset when
switching between graphics modes.
To determine which graphics mode you are using, right-click on the Windows desktop, and then click
Configure Switchable Graphics.
