KB HDD Audio PCI Video Memory CPU The total 8 LEDs light up alternatively if the system fails in one of eight stages. Once the LED7 (latest LED) is lit, this indicates that the system has completed its boot-up procedure. The 8 LEDs indicate the following messages when lit: LED 0 - Indicates that the CPU may have been installed incorrectly or is damaged.

K 57 AK77 Plus / AK77 Pro B a t t e r y - l e s s a n d L o n g Li f e D e s i g n Online Manual This Motherboard implements Flash ROM and a special circuit that allows you to save your current CPU and CMOS Setup configurations without using the battery. The RTC (real time clock) can also keep running as long as the power cord is plugged. If you lose your CMOS data by accident, you can just reload the CMOS configurations from Flash ROM and the system will recover as usual. ATX Stand-by Power Battery Auto Switch RTC (Real Time Clock) 00:00:00 Auto switching to ATX standby power as long as AC power line is plugged. This smart design can increases battery life if you still had battery plugged on motherboard. Flash ROM CMOS Backup by EEPROM 58 AK77 Plus / AK77 Pro O v e r - c ur r e n t P r o t e c t i o n Online Manual It is very popular that the Over Current Protection was implemented on ATX 3. 3V/5V/12V switching power supply. However, the new generation CPU uses different voltages that has regulator to transfer 5V to CPU voltage (for example, 2. 0V), and thus makes 5V over current protection useless. This motherboard is equipped with switching regulator onboard which supports CPU over-current protection; in conjunction with 3. 3V/5V/12V power supply to provide the full line over-current protection. 12V (Protected by power supply) ATX Switching Power Supply 3. 3V (Protected by power supply) 5V (Protected by power supply) Onboard Power Regulator Over-Current Protection Circuit CPU Core Voltage Note: Although we have implemented protection circuit try to prevent any human operating mistake, there is still certain risk that CPU, memory, HDD, add-on cards installed on this motherboard may be damaged because of component failure, human operating error or unknown nature reason. AOpen cannot guaranty the protection circuit will always work perfectly. 59 AK77 Plus / AK77 Pro H a r d w a r e M o ni t o r i n g Online Manual This motherboard implements a hardware monitoring system. As you turn on your system, this smart design will continue to monitor your system's working voltage, fan status and CPU temperature. If any of these systems' status go wrong, there will be an alarm through the AOpen Hardware Monitoring Utility to warn the user. Fan Fan Speed Detection CPU CPU Temperature CPU Voltage AOpen H/W Monitoring Utility Circuit Power System Voltage 60 AK77 Plus / AK77 Pro R e se t ta b l e F u s e Online Manual Traditional motherboard has fuse for Keyboard and USB port to prevent over-current or shortage. These fuses are soldered onboard that user cannot replace it when it is damaged (did the job to protect motherboard), and the motherboard remains malfunction. With expensive Resettable Fuse, the motherboard can resume back to normal function after fuse had done its protection job. Resettable Fuse 61 AK77 Plus / AK77 Pro Year 2000 (Y2K) Online Manual Y2K is basically a problem of the identification of year code. To save storage space, traditional software uses only two digits for year identification. For example, 98 for 1998 and 99 for 1999, but 00 will be confused with 1900 and 2000. There is an RTC circuit (Real Time Clock) in conjunction with 128 bytes of CMOS RAM data in the chipset of the motherboard. Unfortunately, this circuit's behavior is like this 1997 1998 1999 1900, that means it may have the Y2K problem. Below is a diagram of how applications work with the OS, BIOS and RTC.
