OFF your system, press the button and hold it for 4 seconds. You can also change the functions of the
power button in the CMOS setup at power management section.
Infra-Red connector
Serial port 2 can be configured to support an IrDA module via a 5-pin header connector. Once
configured for IrDA, the user can transfer files to or from portable devices such as laptops, PDA’s and
printers using application software such as LapLink. The IrDA specification provides for data
transfers at 115 Kbps from a distance of 1 meter. Consumer IR is also supported by the same
connector.
