Using Battery Power - HP Compaq 100 Reference Manual

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. (For more
information on using battery power, see Chapter 3.)
Starting Up
The notebook starts up with an operating system preinstalled on the hard drive,
a CD-ROM, or a diskette. The notebook will automatically load the operating
system after you turn it on. This process is called booting. Follow these steps to
start the system.
1. Open the notebook by sliding the display latch toward the right and lifting up
the display.
2. Turn on the notebook by pressing the power button (Figure 1-2 #2) on the
left side of the notebook.
3. Tilt the display forward or backward to a comfortable viewing position.
You can also adjust the brightness of the display to attain display clarity. To
adjust brightness, press [Fn]+[F6] or [Fn]+[F7].
4. Each time the notebook is turned on, it performs a Power-On Self Test
(POST). This checks the status of major notebook 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 Setup Configuration Utility
(SCU) program. (See Chapter 5 for instructions on running SCU.)
NOTE: The SCU program allows you to enter the configuration
information and store it in CMOS RAM. The configuration information is
needed by the notebook to identify the installed devices. Under SCU,
you can also activate certain features such as Power Saving and
Security.
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.
NOTE: To avoid viruses brought in by diskettes, boot the system from
the hard disk instead of a diskette. If you must boot up from drive A,
make sure the booting diskette is clean.
