BIOS Utility

The BIOS Utility is a hardware configuration program built into your 

computer's BIOS (Basic Input/Output System).

Your computer is already properly configured and optimized, and you 

do not need to run this utility. However, if you encounter 

configuration problems, you may need to run it.

To activate the BIOS Utility, press F2 during the POST (power on self 

test) while the TravelMate logo is being displayed. See your online 

guide for more information.
