When power returns after an AC power failure, you may choose to either power-on the system manually, let the system power-on automatically or return to the state where you left off before power failure occurs.

ACPI STR

The system board is designed to meet the ACPI (Advanced Configuration and Power Interface) specification. ACPI has energy saving features that enables PCs to implement Power Management and Plug-and-Play with operating systems that support OS Direct Power Management. Currently, only Windows® 98/2000/ME/XP supports the ACPI function allowing you to use the Suspend to RAM function. The Suspend to RAM function is optional.

With the Suspend to RAM function enabled, you can power-off the system at once by pressing the power button or selecting “Standby” when you shut down Windows® 98/2000/ME/XP without having to go through the sometimes tiresome process of closing files, applications and operating system. This is because the system is capable of storing all programs and data files during the entire operating session into RAM (Random Access Memory) when it powers-off. The operating session will resume exactly where you left off the next time you power-on the system.

Virus Protection

Most viruses today destroy data stored in hard drives. The system board is designed to protect the boot sector and partition table of your hard disk drive.

2.2 Using the CPU Temperature Protection Function

The CPU Temperature Protection function has the capability of monitoring the CPU’s temperature during system boot-up. To use this function, set the “CPU Temp. Prot. Function” field to “Enabled” then select the desired CPU temperature limit in the “CPU Temp. Prot. Alarm” field (PC Health Status submenu of the BIOS). Once the system has detected that the CPU’s temperature exceeded the limit, 5 warning beeps will sound and at the same time, a warning message will appear on the boot-up screen instructing you to press <Del> in order to enter the main menu of the BIOS. If you did not press <Del>, the system will automatically power-off after the 5 warning beeps. You may either:

1. Press <Del> then enter a new CPU temperature limit;

2. Allow the system to power-off after the 5 warning beeps then check whether the heatsink and fan are mounted properly onto the CPU because high CPU temperature may be due to incorrect fan/heatsink installation. Now restart the system. If the same problem persist, it may be that the CPU fan is damaged or it is not rotating properly. Try replacing it with a new fan. If it is due to other contributing factors that resulted to high CPU temperature, you may need to set a lower CPU temperature limit.

CPU Temperature References

When you power-up a system, the BIOS message appears on the screen and the memory count begins. After the memory test, the CPU temperature range is normally between 32oC and 35oC. When you run an operating system then tried to reboot the system, the CPU temperature range at this time is between 40oC and 45oC. These temperature references serve as a guide when you select the CPU temperature limit.
