Unable to Turn On System from USB Device
Note that system power supply control using USB devices is not supported.
Unable to Turn On System from Network
❏ Confirm that Wakeup by PCI card in the Power Management Setup is set to
Enabled.
• The measures described below assume there are no problems with customer network
settings and the programs that control this function.
• Note that power cannot be turned on from the network if the system has previously
been turned off by pressing the power switch for a period of 4 or more seconds. In this
case, restart the system using the power switch; then turn the power supply off from a
software application or from Windows.
• The Onboard LAN Device setting in the Integrated Peripherals menu in the
BIOS setup utility must be set to Enabled. Note that the factory default for this setting is
Enabled. When you use not only the power management but also access the network, it
must be set to Enabled.

PS/2 operation, regardless of BIOS settings. (This does not apply in the case of the USB
Keyboard configuration.)

System Time Deviates, Even After Being Set Correctly
❏ If using Windows NT, the Suspend mode setting must not have been set. A design
characteristic of Windows NT is that the time deviates when the system enters the standby
mode.
❏ Confirm whether replacing the main circuit board solves the problem.
