Nothing happens when you type on the keyboard.
The Lockout Timer may be set in SETUP. This option
inactivates the keyboard for a specified period of time after the
system returns to an active mode from a low-power standby
mode. This delay gives Energy Star compliant monitors the
time they need to return to an active mode. Wait a few seconds
and try again.
See “The Computer Does Not Respond,” above
The cursor keys on the numeric keypad do not work
properly.
If the Num Lock light in the upper right corner of the keyboard
is lit, press
NumLock to turn off the function.
If you want to change the initial settings of the num lock
function, see “Setting Keyboard Options” in Chapter 1.
Mouse Problems
Yourmouse isn’t working properly or you see an auxiliary
device error message.
Make sure the mouse cable is securely connected to the MOUSE
port and not the K/Bport. Also make sure you installed the
mouse driver correctly (if necessary). See the documentation
that came with your mouse and Chapter 1 for instructions. (The
Windows installation program automatically installs a mouse
driver for Windows applications.)
