Day 5

ACPI Interface S5 to S0 state (Day 5)

• Practical

ACPI must be supported by the computer motherboard, basic input/output system (BIOS), and the operating system. One of several power schemes can be chosen. Within a power scheme, the user can control the power to individual devices. In order for ACPI to work on your computer, your BIOS must include the ACPI software and the operating system must be ACPI-compatible.

Day 6

Super IO Controller (Day 6)

• Theory

Identifying the Super I/O on your motherboard is often easy if you look for an integrated circuit that is labeled with a company name that manufacturers Super I/O chips. Some common Super I/O manufacturers are Fintek, ITE, National Semiconductor, Nuvoton, SMSC, VIA, and Winbond.

Day 7

LCD / LED (Day 7)
