Notebook PC E-Manual

The Power-on Self Test (POST)  is a series of software-controlled 

diagnostic tests that run when you turn on or restart your Notebook 

PC. The software that controls the POST is installed as a permanent 
part of the Notebook PC’s architecture. 

During POST, you can access the BIOS settings or run 

troubleshooting options using the function keys of your Notebook 

PC. You may refer to the following information for more details. 

The Basic Input and Output System (BIOS) 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.

Restart your Notebook PC then press 

 during POST.
