9.3 BIOS Power Management
The T410 BIOS provides a Performance/Power page in the BIOS configuration screen, and these BIOS
features are consolidated into a single page. The BIOS will also provide user-friendly Power Profiles
that adjust various BIOS settings.
Concerning the Power Profiles, some of the power management settings can be grouped together. A
group of a set of different parameters is called Power Profile. The BIOS setup provides five options:
OS Control, Active Power Controller, Static Max Performance, and Custom. OS Control mode is the
default mode.
9.4 I
2
C (Inter-Integrated Circuit)
I
2
C is a simple bi-directional two-wire bus for efficient inter-integrated circuit control. All I
2
C -bus
compatible devices incorporate an on-chip interface that allows them to communicate directly with
each other via the I
2
C-bus. This solves the many interfacing problems encountered when designing
digital control circuits. These I
2
C devices perform communication functions between intelligent
control devices (such as microcontrollers), general-purpose circuits (such as LCD drivers, remote I/O
ports, memories), and application-oriented circuits.
