AppendixAB9 Pro, AB9 5-55.2 Troubleshooting (How to Get Technical Support?)5.2.1 Q & AQ: Do I need to clear the CMOS before I use a new motherboard to assemble mynew computer system?A: Yes, we highly recommend that you clear the CMOS before installing a new motherboard.Please move the CMOS jumper from its default 1-2 position to 2-3 for a few seconds, andthen back. When you boot up your system for the first time, follow the instructions in theuser's manual to load the optimized defaults.Q: If my system hangs when I update the BIOS or set the wrong CPU parameters,what should I do?A: Whenever you update the BIOS or if the system hangs due to wrong CPU parameterssetting, always clear CMOS jumper before booting up again.Q: Why does the system fail to boot up again right after a mechanical power-off?A: Please keep a 30-second interval between each mechanical power On/Off.Q: Why does the system fail to boot up and nothing displays on the screen after Idid some over-clocking or non-standard settings inside the BIOS?A: It should not cause hardware or permanent damage to motherboard when BIOS settingswere changed from default to over-clocking or non-standard status.We suggest the following three troubleshooting methods to discharge CMOS data, recoverthe hardware default status, and then making the motherboard work again. There is noneed to bother returning the motherboard to where you bought it from or go through anRMA process.Step 1.Switch off the power supply unit and then switch it on again after one minute. Ifthere is no power-switch on the power supply unit, disconnect its power cord forone minute and then reconnect.Press and hold the key on the keyboard, and press the power-on buttonto boot up system. If it works, release the key and hit ~~key to enter~~the BIOS setup page to apply the correct settings.If the situation remains the same, repeat the procedures in Step 1 for three times,or try Step 2.Step 2.Switch off the power supply unit or disconnect the power cord. Open the chassiscover. Locate the CCMOS jumper near the button battery. Change the jumperposition from default 1-2 to 2-3 for one minute to discharge the CMOS data, andthen put it back to default 1-2 position.Close the chassis and switch on the power supply unit or plug in the power cord.Press the power-on button to boot up system. If it works, hit ~~key to enter~~the BIOS setup page to do the correct settings.If the situation remains the same, try Step 3.Step 3.The same procedure as Step 2, but while discharging the CMOS data, pull out theATX power connectors from motherboard and remove the button battery duringCMOS discharge.
