Call Center: Suggestions
Check cables and connections.
Try connecting notebook to another
network station (if applicable). If
green light next to LAN port does not
light, LAN cable may not be
connected to network or network

Use networking troubleshooter in
Windows Help.
Check settings in Control Panel.
Make sure LAN cable is Category 3,
4, or 5 for 10Base-T operation,
or Category 5 for 100Base-TX
operation. Maximum cable length is
100 meters (330 feet).
Test LAN with e-Diagtools

installed as shipped. (Drivers are

Make sure line between infrared
ports is not blocked, ports face each

nearby equipment, or other sources
of infrared radiation can cause
transmission errors.
Open Hardware Device Manager. Try
to enable the infrared port.
Remove any PC cards from

For fast-IrDA, check for DMA conflict

associated with buttons in One-
