Gigabyte N4120I H User Manual

8) 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.
9) 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 cable:
1. Turn off your computer and unplug the power cord.
2. Unplug the the battery cable from the battery cable header and wait for
one minute.
3. Plug in the battery cable.
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.
• Used batteries must be handled in accordance with local environmental regulations.
