3-3 BIOS test and setting
When the power supply of the laptop is turned on, a series of diagnostic tests controlled by
software will be performed at first on the screen, generally known as POST (power-on self-test).
POST is operated at first every time the laptop is started. If no error appears in POST, the
operating system will be enabled; otherwise, the error warning of BIOS setting memory loss
caused by improper setting or long-time power loss will appear. You can use the function keys to
read/write the BIOS setting program or operation troubleshooting options. Refer to the following
instructions for more details.
BIOS (basic input/output system) is used to save system hardware configuration required for
laptop start-up. The default BIOS settings are applicable to most of operating conditions of the
laptop and must not be changed except in the following cases:
◆
The error tip appears when the system is started, requiring you to operate the BIOS
settings.
◆
You have installed a new system component requiring further BIOS setting or updating.
The use of improper BIOS settings may result in system instability or start-up
failure. It is strongly recommended to change BIOS settings with the help of
professional personnel.
How to enter the BIOS setting program:
Restart the laptop and press
in POST.
