Using Battery Power

When the AC adapter is not connected, you can use battery power.
To assure optimum battery life, fully charge and discharge the battery
at least once and then fully charge the battery before you first use
battery power. (See Chapter 3 for more information on using battery
power.)

Starting Up

A computer starts up with an operating system existing on the hard
disk, a CD, or a diskette. The computer will automatically load the
operating system after you turn it on. This process is called booting.
The notebook comes to you ready for use. This means the hard disk
is pre-formatted and contains the files necessary for booting.
1. Open the top cover by sliding the cover latch toward the right and
lifting up the cover.
2. Turn on the notebook by pressing the Power Switch (Figure 1-6
#3).
3. Tilt the cover forward or backward to a comfortable viewing
position.
4. Each time the notebook is turned on, it performs a Power-On Self
Test (POST). This checks the status of major computer devices
including the system board, memory, video, keyboard, and disk
drive. Some status messages from POST will appear on the
screen. If the POST has detected a mismatch between the actual
hardware configuration and the configuration information stored in
CMOS RAM, you will see error message(s) telling you to run the
SCU program. (See Chapter 5 for instructions on running SCU.)
5. When POST successfully completes its check, the notebook first
tries to boot from drive A, C, or CD-ROM depending on the "Boot
Sequence" setting in the SCU program.

Turning Off the Notebook

1. If you are using a program, save your data and exit the program.
2. First make sure all disk drive in-use indicators are off, then remove
any diskette or CD from the drive.
3. Click the Start button on the Windows desktop, select Shut Down,
then Shut Down, and then click OK and the computer will turn off
automatically. Otherwise, turn off the notebook by pressing the
Power Button.
4. To close the top cover, tilt down the cover until the cover latch
clicks into place.
5. To disconnect the AC adapter, unplug from the electrical outlet
first; then unplug from the notebook.
