To read more FAQs for your motherboard, please go to the Support&Downloads\FAQ page on GIGABYTE's
website.
Q: Why is the light of my keyboard/optical mouse still on after the computer shuts down?
A: Some motherboards provide a small amount of standby power after the computer shuts down and that's why the light is still
on.
Q: How do I clear the CMOS values?
A: For motherboards that have a Clear CMOS button, press this button to clear the CMOS values (before doing this, please turn
off the computer and unplug the power cord). For motherboards that have a Clear CMOS jumper, refer to the instructions in
Chapter 1 to short the jumper to clear the CMOS values. If your board doesn't have this jumper/button, refer to the instructions
on the motherboard battery in Chapter 1. You can temporarily remove the battery from the battery holder to stop supplying
power to the CMOS, which will clear the CMOS values after about one minute.
Q: Why do I still get a weak sound even though I have turned my speaker to the maximum volume?
A: Makesureyourspeakerisequippedwithaninternalamplier.Ifnot,tryaspeakerwithpower/amplier.
