Notebook PC User Manual

IMPORTANT! To protect the hard disk drive, always wait at least

5 seconds after turning OFF your Notebook PC before turning it

back ON.

WARNING! DO NOT carry or cover a Notebook PC that is

powered ON with any materials that will reduce air circulation

such as a carrying bag.

Before bootup, the display panel ﬂashes when the power is

turned ON. This is part of the Notebook PC’s test routine and is

not a problem with the display.

Powering ON the Notebook PC

The Notebook PC’s power-ON message appears on the screen when

you turn it ON. If necessary, you may adjust the brightness by using

the hot keys. If you need to run the BIOS Setup to set or modify the

system conﬁguration, press [F2] upon bootup to enter the BIOS

Setup. Press [ESC] and you will be presented with a boot menu with

selections to boot from your available drives.

The Power-On Self Test (POST)

When you turn ON the Notebook PC, it will ﬁrst run through a

series of software-controlled diagnostic tests called the Power-On

Self Test (POST). The software that controls the POST is installed

as a permanent part of the Notebook PC’s architecture. The POST

includes a record of the Notebook PC’s hardware conﬁguration,

which is used to make a diagnostic check of the system. This record

is created by using the BIOS Setup program. If the POST discovers

a difference between the record and the existing hardware, it will

display a message on the screen prompting you to correct the

conﬂict by running BIOS Setup. In most cases the record should be

correct when you receive the Notebook PC. When the test is ﬁnished,

you may get a message reporting “No operating system found” if the

hard disk was not preloaded with an operating system. This indicates

that the hard disk is correctly detected and ready for the installation

of a new operating system.
