Troubleshooting Your Computer
If the embedded numeric keypad doesn’t work
• To type numbers, make sure Num Lock is on.
• Make sure the embedded Keypad Lock (Fn+F8) is on—or that you press and hold the
Fn key to temporarily access the embedded keypad.
If you can’t type the euro symbol
• Hold ALT GR when you press the marked key.
• The euro symbol is not on the U.S. English keyboard. Make sure the embedded
keypad is active (Fn+F8) and Num Lock is on, and then hold ALT while typing 0128
on the numeric keypad.
If you can’t update or reinstall One-Touch software
• Log in as administrator to perform the update or installation.
LAN Problems
If the built-in network adapter doesn’t connect to the LAN
• Check all cables and connections. Try connecting at a different network station, if
available.
• If the yellow light next to the LAN port does not light, the LAN cable may not be
connected to the network or the network may be down. Try connecting a different
computer to the cable.
• Make sure the 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).
• Click Start, Help and Support, and use the Networking troubleshooter.
• Open the hardware Device Manager: click Start, Control Panel, Performance and
Maintenance, System. If the network interface is disabled, try to enable it. If it has a
conflict, try disabling another device.
If you can’t browse the Network Neighborhood or My Network Places
• Click Start, Search, Computers or People to look for a computer.
