CHAPTER 6: Troubleshooting

Problem:

Your keyboard does not function or functions only intermittently. The Num Lock

LED does not always light when the Num Lock key is pressed.

Possible Solution:

Some older keyboards were designed for use with specific computers and are not

truly PC/AT or PS/2 compatible. These are not common, but if you’re having

problems like this and you’re using an old keyboard, try a newer keyboard.

Problem:

Just using your mouse normally causes the CPU channel to change unexpectedly.

Possible Solutions:

Some cheaper mice are not fully compatible with the ServSwitch Wizard and can

lose data, which—if mouse switching is enabled (see Section 4.2.6)—sometimes

causes the Wizard to interpret a data stream as a channel-change request. Try using

a Microsoft, Logitech, IBM, Compaq

, or Hewlett-Packard

mouse instead.

Make sure that you are using a Microsoft compatible mouse driver on your PC.

Some drivers by other manufacturers can cause the mouse to use proprietary

mouse-data formats that the Wizard doesn’t support. If you have unplugged and

reconnected a mouse to the ServSwitch Wizard, make sure that you reset it (see

Section 5.7) or—especially if the mouse is an IntelliMouse—use the mouse-

restoration function (see Section 5.8).

Problem:

The mouse moves very slowly but otherwise functions correctly.

Possible Solutions:

Change to a Microsoft mouse driver or set the Wizard to the “L6” configuration

option. See Section 4.2.4.

Problem:

The cursor/pointer jumps around the screen after you disconnect the mouse cable

or power down the ServSwitch Wizard.

Possible Solution:

If you have disconnected and reconnected a CPU mouse cable or you have

powered down the ServSwitch Wizard, and you’re using a PS/2 mouse or

IntelliMouse, the mouse might have gotten out of sync with the CPU. Try the

mouse-reset function (see Section 5.7) or the mouse-restoration function (see

Section 5.8), or reboot the CPU.
