The AC adapter provides power for operating your notebook PC and charging the
battery. Connecting the AC Adapter
- Plug the DC output cable into the DC power jack of your notebook PC.
- Plug the AC adapter into an AC electrical outlet.
Switching from AC Adapter Power to Battery Power
- Be sure that you have at least one charged battery installed.
- Remove the AC adapter. Your notebook will automatically switch to battery power.
CAUTION: The Lithium-Ion battery is not charged upon purchase. Initially, you will need to connect the AC adapter to use your notebook PC.
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. 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 computer from damage, use only the power adapter that came with it because each power adapter has its own power output rating.
STARTING YOUR NOTEBOOK

Once you have connected your AC adapter or charged the internal Lithium-Ion battery, you can power on your notebook by pressing the suspend /power-on button located above the keyboard. If you need to take an extended break press the button again to turn it off.
CAUTION: Do not carry your notebook around with the power on or subject
it to shocks or vibration, as you risk damaging the hard disk.

to check the internal parts and configuration for correct functionality. If a
fault is found. your computer emits an audio warning and or displays an error
message.

starting the operating system or by entering the BIOS setup utility and
revising the settings. After satisfactory completion of the Power On Self Test
(POST), your notebook loads the installed operating system.
