The Power-on Self Test (POST)
The Power-on Self Test (POST) is a series of software-controlled
diagnostic tests that run when you turn on or restart your ASUS
Transformer Book. The software that controls the POST is installed as
a permanent part of the ASUS Transformer Book’s architecture.
Using POST to access BIOS and Troubleshoot
During POST, you can access the BIOS settings or run troubleshooting
options using the function keys of your ASUS Transformer Book. You
may refer to the following information for more details.
BIOS
The Basic Input and Output System (BIOS) stores system hardware
settings that are needed for system startup in the ASUS Transformer
Book.
The default BIOS settings apply to most conditions of your ASUS
Transformer Book. 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 ASUS Transformer Book then press
during POST.
