battery. Wait for a few seconds and install it back before

AC Power Failure Recovery
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. Refer to “PWR Lost Resume State” in the Integrated

ACPI
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 supports the ACPI
function. ACPI when enabled in the Power Management Setup will
allow you to use the Suspend to RAM function.
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 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. Refer to “Using the Suspend to RAM
Function” in appendix A for more information.
Important:
The 5VSB power source of your power supply must support a
minimum of 1.5A.
