The Power-on Self Test (POST)
When you turn on the Notebook PC, it runs 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. 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.
BIOS
The BIOS (Basic Input and Output System) stores system hardware
settings that are needed for system startup in the Notebook PC.
The default BIOS settings apply to most conditions of your Notebook
PC. Do not change the default BIOS settings except in the following
circumstances:
• An error message appears onscreen during system bootup and
requests you to run the BIOS Setup.
• You have installed a new system component that requires
further BIOS settings or updates.
WARNING: Using inappropriate BIOS settings may result to system
instability or boot failure. We strongly recommend that you change
the BIOS settings only with the help of a trained service personnel.
Accessing BIOS
Restart your Notebook PC then press during POST.
