19 Power Sources Your computer has two types of power sources: a Lithium-Ion battery or an AC adapter. CONNECTING THE POWER ADAPTERS The AC adapter provides power for operating your notebook PC and charging the battery. Connecting the AC Adapter 1. Plug the DC output cable into the DC power jack of your notebook PC. 2. Plug the AC adapter into an AC electrical outlet. Switching from AC Adapter Power to Battery Power 1. Be sure that you have at least one charged battery installed. 2. Remove the AC adapter. Your notebook will automatically switch from DC power to battery power. Note: The Lithium-Ion battery is not charged upon purchase. Initially, you will need to connect the AC adapter to use your notebook PC.
20 RECHARGING THE BATTERY The Lithium-Ion battery is recharged internally using the AC adapter. To recharge the battery, make sure the battery is installed and the computer is connected to the AC adapter. There is no "memory effect" in Lithium-Ion batteries; therefore, you do not need to discharge the battery completely before recharging. The charge times will be significantly longer if your notebook PC is in use while the battery is charging. If you want to charge the battery more quickly, put your computer into Suspend mode or turn it off while the adapter is charging the battery. Low Battery State When the battery charge is low, a notification message appears. If you do not respond to the low battery message, the battery continues to discharge until it is too low to operate. When this happens, your notebook PC goes into Suspend mode. There is no guarantee your data will be saved once the notebook reaches this point. Caution: To protect your notebook from damage, use only the power adapter that came with it because each power adapter has its own power output rating. Once your notebook PC goes into Suspend mode as a result of a dead battery, you will be unable to resume operation until you provide a source of power either from an adapter or a charged battery. Once you have provided power, you can press the Suspend/ Resume button to resume operation. In Suspend mode, your data is maintained for some time, but if a power source is not provided promptly, the Power indicator stops flashing and then goes out, in which case you have lost the data that was not saved. Once you provide power, you can continue to use your computer while an adapter charges the battery.
21 Battery Replacement There is danger of explosion if an incorrect battery type is used for replacement. For computers equipped with a replaceable lithium-ion battery pack, the following applies: • If the battery is placed in an OPERATOR ACCESS AREA, there shall be a marking close to the battery, or a statement in both the operating and the servicing instructions; • If the battery is placed elsewhere in the computer, there shall be a marking close to the battery or a statement in the servicing instructions. The marking or statement shall include the following or similar text: Caution: Risk of explosion if battery is replaced with an incorrect type. Dispose of used batteries according to the instructions. Standby and hibernation Standby and hibernation are energy-saving features that conserve power and reduce startup time. They can be initiated by you or by the system. For more information, refer to "Initiating standby, hibernation or shutdown." Standby CAUTION: To avoid a complete battery discharge, do not leave the computer in standby for extended periods. Connect the computer to an external power source. Standby reduces power to system components that are not in use. When standby is initiated, your work is stored in random access memory (RAM), and then the screen is cleared. When the computer is in standby,
22 the power lights blink. When you resume from standby, your work returns to the screen where you left off. CAUTION: To reduce the risk of information loss, save your work before initiating standby. Hibernation CAUTION: If the configuration of the computer is changed during hibernation, resuming from hibernation may not be possible. When the computer is in hibernation: Do not connect the computer to or disconnect the computer from an expansion product. Do not add or remove memory modules. Do not insert or remove any hard drives or optical drives. Do not connect or disconnect external devices. Do not insert or remove an external media card, such as a MultiMediaCard. Hibernation saves your work to a hibernation file on the hard drive, and then shuts down the computer. The power lights are turned off. When you restore from hibernation, your work returns to the screen where you left off. If a power-on password has been set, the password must be entered to restore from hibernation. CAUTION: To reduce the risk of information loss, save your work before initiating hibernation. You can disable hibernation. However, if hibernation is disabled and the system reaches a lowbattery condition, the system will not automatically save your work while power is on or when standby has been initiated. Initiating standby, hibernation or shutdown The following sections explain when to initiate standby or hibernation and when to shut down the computer.
23 NOTE: You cannot initiate any type of networking communications or perform any computer functions while the computer is in standby or hibernation. When you leave your work When standby is initiated, your work is stored in random access memory (RAM), and then the screen is cleared. When the computer is in standby, it uses less power than when it is on. Your work returns instantly to the screen when you resume from standby. Hibernation saves your work to a hibernation file on the hard drive, and then shuts down the computer. When the computer is in hibernation, it uses much less power than when it is in standby. When the computer will be unused and disconnected from external power for an extended period, shut down the computer and remove the battery pack to extend the life of the battery pack. For details on battery pack storage, refer to "Storing a battery pack." When a reliable power supply is unavailable Be sure that hibernation remains enabled, especially if you are operating the computer on battery power and do not have access to an external power supply. If the battery pack fails, hibernation saves your work to a hibernation file and shuts down the computer. It is recommended that if you pause your work when the power supply is uncertain, you take one of the following actions: • Save your work, and then initiate standby. • Initiate hibernation. • Shut down the computer.
24 Drives Optical drives An optical drive, such as a DVD-ROM drive, supports optical discs (CDs and DVDs). These discs are used to store or transport data and to play music and movies. DVDs have a higher capacity than CDs. The computer can read or write to optical drives as described in the following table.
