■ USB hub (Windows 2000 models)
Depending on the type of USB hub you are using, your PC may return to full-power operation
immediately after shifting to standby mode (ACPI S3). To prevent this, from [System Properties]
select [Device Manager], then open the properties for the device connected to the USB hub.
Uncheck [Allow this device to cause the computer to exit standby and return to full-power operation.]
on [Power Management] tab.
■ Addition of LAN adapter
When this PC is operated as a client and a LAN adapter is added, the adapter cannot be used
simultaneously with the standard LAN function.
To use several LAN adapters at the same time, a server OS such as Windows NT 4.0 Server and
Windows 2000 Server is required.
■ Precautions on using display
Depending on the setting of the display used (ex. resolution), the thicknesses of the vertical and
horizontal lines may seem to be different on CAD or other application. If such difference is detected,
adjust the setting.

blank screen may occur. In this case, replace the display as follows:

If nothing appears or some resolutions are unavailable after the display is replaced without the
above setting, reinstall the display driver as follows:
