Configure Laptop Power Settings ACPI Standards S 0 The computer is on and the CPU is running. S 1 The CPU is not running. However, the CPU and RAM are still receiving power. S 2 The CPU is off, but the RAM is refreshed. The system is in a lower power mode than S 1. S 3 S 4 S 5 ITE PC v 4. 0 Chapter 6 The CPU is off, and the RAM is set to a slow refresh rate. This mode is often called “Save to RAM”. In Windows XP, this state is known as the Standby mode. The CPU and RAM are off. The contents of RAM have been saved to a temporary file on the hard disk. This mode is also called “Saved to Disk”. In Windows XP, this state is known as the Hibernate mode. The computer is off and nothing has been saved. © 2007 Cisco Systems, Inc. All rights reserved.

Checking the ACPI Settings in the BIOS Here are the steps to check the ACPI settings in the BIOS: 1. Enter BIOS setup by pressing the appropriate key or key combination while the computer is booting. Typically this is the Delete key or the F 2 key, but there are several other options. 2. Locate and enter the “Power Management settings” menu item. 3. Use the appropriate keys to enable ACPI mode. 4. Save and Exit BIOS setup. ITE PC v 4. 0 Chapter 6 © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public 29
