If the touch pad or scroll pad doesn't work
• Don't use the touch pad or scroll pad while the notebook is rebooting or resuming. If
this happens, try the following:
• Press any key on the keyboard.
• Put the notebook on standby, then resume operation.
• The touch pad and scroll pad are automatically disabled when the notebook is docked
in a port replicator that has a PS/2 mouse connected.
• Restart the notebook: click Start, Turn Off Computer, Restart.
• Check settings: click Start, Control Pad, Printers and Other Hardware, Mouse,
Scrolling.
• Test the keyboard and pointing devices with the e–DiagTools diagnostics—see
"Testing the Hardware" on page 119.
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, then hold Alt while typing 0128 on the
numeric keypad.
• Support for the euro symbol requires software available from Microsoft. This
software is installed in the factory software, but may not be included with retail
Windows.
If a special feature on a USB mouse doesn't work
• Make sure you installed any drivers included with the mouse.
• Restart the notebook, so that it will detect the mouse.
