To clear the CMOS
Under some unusual circumstances, the configuration record created by the CMOS Setup
utility can become corrupted and unusable. This can cause the motherboard to stop
functioning properly. In such cases, you need to clear the CMOS record by using jumper JP19.
To clear the CMOS
1. Switch off the computer.
2. Remove the jumper cap from JP19 pins 1 and 2.
3. Place the jumper cap over JP19 pins 2 and 3 for two seconds.
4. Remove the jumper cap from pins 2 and 3.
5. Place the jumper cap back on pins 1 and 2.
