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.
