NOTE: For additional information about the power meter, refer to "Using the power meter" section. The computer takes the following actions for a critical battery level: ● If Hibernation is disabled and the computer is on or in the Sleep state, the computer remains briefly in the Sleep state, and then shuts down and loses any unsaved information. ● If Hibernation is enabled and the computer is on or in the Sleep state, the computer initiates Hibernation. Resolving a low battery level Resolving a low battery level when external power is available ● Connect an AC adapter. ● Connect an optional docking or expansion device. ● Connect an optional power adapter purchased as an accessory from HP. Resolving a low battery level when no power source is available 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 user-replaceable battery with a charged battery, or connect the AC adapter to the computer and to external power. 2. Exit Hibernation by pressing the power button. Storing a user-replaceable battery CAUTION: To reduce the risk of damage to a battery, do not expose it to high temperatures for extended periods of time. If your computer will be unused and unplugged from external power for more than 2 weeks, remove the battery and store it separately in a cool, dry place to prolong the battery charge. A stored battery should be checked every 6 months. If the capacity is less than 50 percent, recharge the battery before returning it to storage. Disposing of a user-replaceable battery WARNING! To reduce the risk of fire or burns, do not disassemble, crush, or puncture; do not short external contacts; do not dispose of in fire or water.
