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. If you press [Tab] during the splash screen, standard boot 
information such as the BIOS version can be seen. 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.
