The following power plans are available: ● Power saver ● HP Recommended ● High performance To start Power Manager when Windows is running: ▲ Select Start > Control Panel > Hardware and Sound > HP Power Manager. Using battery power When a charged battery is in the computer and the computer is not plugged into external power, the computer runs on battery power. When the computer is plugged into external AC power, the computer runs on AC power. If the computer contains a charged battery and is running on external AC power, the computer switches to battery power if the AC adapter is disconnected from the computer. NOTE: When you disconnect AC power, the display brightness is automatically decreased to save battery life. For information on increasing or decreasing display brightness, see Using the action keys on page 28. 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. 44 Chapter 6 Power management
