Wake from USB

NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB
and an operating system that supports Wake from USB.
USB bus activity wakes the computer from an ACPI S1 or S3 state.

PCI Express WAKE# Signal Wake-up Support

When the WAKE# signal on a PCI Express bus add-in card is asserted, the computer
wakes from an ACPI S1, S3, S4, or S5 state.

Wake from CIR

Consumer IR device activity wakes the computer from an ACPI S1 or S3 state.

Speaker

A speaker is mounted on the Desktop Board. The speaker provides audible error code
(beep code) information during the Power-On Self-Test (POST). Refer to Appendix A
for a description of the board's beep codes.

Real-Time Clock Subsystem

A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When
the computer is not plugged into a wall socket, the battery has an estimated life of
three years. When the computer is plugged in, the standby current from the power
supply extends the life of the battery.
The clock is accurate to ± 13 minutes/year at 25 ºC with standby power applied by the
power supply.
NOTE
If the battery and AC power fail, date and time values will be reset and the user will be
notified during the POST.
When the battery voltage drops below a certain level, the BIOS Setup program
settings stored in CMOS RAM (for example, the date and time) might not be accurate.
Replace the battery with an equivalent one. Go to page 54 for instructions on how to
replace the battery.
