3 Using Battery Power The primary difference between using battery power and AC power is the limited time you can operate before you must recharge. This chapter covers charging the battery and maximizing the time between charges and assumes that you installed and charged the battery as directed in the Quick Start instructions. Contents Guidelines for Battery Use ........................... 3-2 Switching to Battery Power .......................... 3-3 Responding to Low Battery Conditions .........
Guidelines for Battery Use ! Caution: Never dispose of exhausted batteries in a fire. Recycle if possible. The battery should be handled carefully to ensure maximum life. In particular: Do not drop the battery or subject it to shocks. Do not expose the battery to direct sunlight, moisture, chemicals, or temperature extremes. Do not short the battery leads or insert the battery upside down. Charge the battery after several days of disuse to keep it fully charged.
Switching to Battery Power This procedure should only be done if your battery currently has charge remaining. The Duracell NiMH battery pack is “hot-pluggable”. To use battery power, install batteries as described in Installing the Battery Pack later in this section. Your computer will automatically switch to AC power whenever an AC adapter is plugged into the notebook. At this time, your battery will automatically be recharged.
Responding to Low Battery Conditions The notebook has battery-low warning signals that are both audible and visible. When the battery has 5% to 10% of its charge remaining, the power indicator light found to the left of the power switch flashes at regular intervals until the battery power is depleted. The buzzer also generates four continuous beeps every minute if you enabled the BATTERY-LOW WARNING BEEP parameter in Setup.
Responding to Low Battery Conditions Turn off the computer if it does not need to be active. Once your system enters suspend-to-disk mode, you can replace with a fully-charged battery and then resume from suspend to disk mode or connect AC power.
Recharging the Battery ! Caution: Never recharge the battery differently from the procedure described in this manual. The following procedure is acceptable under most circumstances: 1. Install the battery pack in your computer (if not already installed). 2. Connect the AC adapter as described in Chapter 1. When the notebook is turned off, the battery charging indicator turns on. This is called rapid charge mode. When the notebook is turned on, the notebook switches to charge-in-use mode.
Conditioning the Battery The Duracell battery is a Nickel-Metal-Hydride (NiMH) rechargeable battery. NiMH batteries require occasional conditioning to maintain a full battery charge. An unconditioned NiMH battery may hold less than half of full charge. You should condition the battery when you first use your computer and after every three to five shallow discharges, that is, after you use only a small portion of the battery charge before recharging the battery.
Removing and Installing the Battery Pack Removing the Battery Pack Follow these steps to remove the battery: ! Caution: Turn off the notebook or enter suspend mode before removing a battery pack. 1. Remove the battery compartment cover. 2. Release the battery by pulling on the loop attached to the battery.
