22Chapter 1 NOTE: DC-AC inverter is used to generate very high AC voltage, to support LCD CCFT backlight user, and it is also responsible for the control of LCD brightness. Avoid touching the DC-AC inverter area while the system unit is turned on. NOTE: There is an EEPROM in the inverter, which stores its supported LCD type and ID code. If you replace a new inverter or replace the LCD with one of a different brand, use Inverter ID utility to update the ID information.

Or When the computer is about to enter Hibernation mode (e.g., during a battery-low condition), but the Hibernation file is invalid or not present. The buzzer beeps The Standby indicator lights up Hibernation Mode When customized functions for power management are set to Hibernation and the corresponding action is taken. All power shuts off Display Standby Mode Keyboard, built-in touchpad, and an external PS/2 pointing device are idle for a specified period. The display shuts off Hard Disk Standby Mode Hard disk is idle within a specified period of time. Hard disk drive is in standby mode.
