Setting power options Using power-saving states The computer has two power-saving states enabled at the factory: Suspend and Hibernation. When Suspend is initiated, the power lights blink and the screen clears. Your work is saved to memory, letting you exit the Suspend state faster than exiting Hibernation. If the computer is in the Suspend state for an extended period or if the battery reaches a critical battery level while in the Suspend state, the computer initiates Hibernation.
With the computer on, you can initiate Hibernation in any of the following ways: ● Briefly press the power button. ● Select Computer > Shutdown > Hibernate. ● Click the Power icon, located on the far right of the taskbar, and then click Hibernate. To exit Hibernation: ▲ Briefly press the power button. When the computer exits Hibernation, the power lights turn on and your work returns to the screen where you stopped working.
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 17. 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.
CAUTION: Removing a battery that is the sole power source for the computer can cause loss of information. To prevent loss of information, save your work and initiate Hibernation or shut down the computer before removing the battery. 1. Slide the battery release latch (1) to release the battery. 2. Tilt the battery (2) to remove it, and then lift it out of the battery bay (3). Charging a battery WARNING! Do not charge the computer battery while you are onboard aircraft.
Maximizing battery life To maximize battery life: 1. Select Computer > Control Center > Power Management. 2. On the On Battery Power tab: ● Adjust the slider to the right of Put computer to sleep when inactive for to 30 minutes. ● Select the Suspend or Hibernate option to the right of When laptop lid is closed. ● Select the Hibernate or Shutdown option to the right of When battery power is critically low. 3.
Resolving a low battery level when no power source is available ● Initiate Hibernation. ● Save your work and shut down the computer. Resolving a low battery level when the computer cannot exit Hibernation When the computer lacks sufficient power to exit Hibernation, follow these steps: 1. Replace the discharged battery with a charged battery, or connect the AC adapter to the computer and to external power. 2. Exit Hibernation by briefly pressing the power button.
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. Using external AC power NOTE: For information on connecting to AC power, refer to the Start Here poster provided in the computer box. External AC power is supplied through an approved AC adapter or an optional docking or expansion device.
Testing an AC adapter Test the AC adapter if the computer exhibits any of the following symptoms when it is connected to AC power: ● The computer does not turn on. ● The display does not turn on. ● The power lights are off. To test the AC adapter: 1. Shut down the computer. 2. Remove the battery from the computer. 3. Connect the AC adapter to the computer, and then plug it into an AC outlet. 4.
