17) BAT (Battery)
 Thebatteryprovidespowertokeepthevalues(suchasBIOScongurations,date,andtimeinformation)
in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a low
level, or the CMOS values may not be accurate or may be lost.
You may clear the CMOS values by removing the battery:
1. Turn off your computer and unplug the power cord.
2. Gently remove the battery from the battery holder and wait for one minute. (Or use a
metal object like a screwdriver to touch the positive and negative terminals of the battery
holder, making them short for 5 seconds.)
3. Replace the battery.
4. Plug in the power cord and restart your computer.
• Always turn off your computer and unplug the power cord before replacing the battery.
• Replacethebatterywithanequivalentone.Damagetoyourdevicesmayoccurifthebatteryis
replaced with an incorrect model.
• Contact the place of purchase or local dealer if you are not able to replace the battery by yourself
or uncertain about the battery model.
• When installing the battery, note the orientation of the positive side (+) and the negative side (-)
of the battery (the positive side should face up).
• Used batteries must be handled in accordance with local environmental regulations.
16) F_AUDIO (Front Panel Audio Header)
 ThefrontpanelaudioheadersupportsHighDenitionaudio(HD).Youmayconnectyourchassisfront
panel audio module to this header. Make sure the wire assignments of the module connector match the
pin assignments of the motherboard header. Incorrect connection between the module connector and the
motherboard header will make the device unable to work or even damage it.
Some chassis provide a front panel audio module that has separated connectors on each wire instead
of a single plug. For information about connecting the front panel audio module that has different wire
assignments, please contact the chassis manufacturer.
