PSS ID Number: 190524

- Microsoft Win32 Device Driver Kit (DDK) Windows 98
This article was previously published under Q190524
SYMPTOMS
Windows 98 does not allow the system to enter a "standby" power state.
Instead, the system might enter a "suspend" power state.
CAUSE
Windows 98 does not support the "standby" power state. If the BIOS requests
standby, Windows 98 rejects the standby request and sets the system power
state to suspend if suspend is supported.
STATUS
This behavior is by design.
MORE INFORMATION
According to section 4.3.1 of the Advanced Power Management 1.2
specification, event code 1 is for standby requests. Windows 95 attempts to
set the system power state to standby when handling this BIOS event
request. However, Windows 98 rejects a standby request and attempts to
suspend the system if suspend is supported.
