The Keyboard Does Not Work
NOTE Use only an HP-Approved Keyboard as others may not work correctly.
If the keyboard does not work or a character is not displayed when a key is pressed:
1. Ensure that the keyboard is not locked, if the HP Server has this feature.
2. Ensure that the keyboard cable connections at the rear of the HP Server and at the back of the keyboard
are secure.
NOTE Make sure the keyboard is plugged into the keyboard port and not into the mouse port in
the back of the server.
3. If the KVM switchbox is used with this HP Server, remove the keyboard and plug the keyboard directly
into the keyboard port of the HP Server.
4. Try replacing the keyboard with a known good keyboard, and then reboot the HP Server.
5. If there is a keyboard extender cable, make sure the connection is secure or remove the extender and
plug the keyboard directly into the HP Server.
If the problem persists, contact the HP Customer Support Center for more troubleshooting steps before
replacing any parts.
The Mouse Does Not Work
The HP Server automatically detects a mouse when one is installed. If the mouse or other input device is not
working, check the following:
1. Verify that the mouse cable is properly and securely connected to the HP Server or KVM switch box.
2. If a KVM switch box is used with this HP Server, remove the mouse and plug the mouse directly into
the mouse port on the HP Server.
NOTE Make sure the mouse is plugged into the mouse port and not the keyboard port.
3. Ensure that the mouse port does not have a resource conflict with another device. Use the system BIOS
Setup Utility (F2) to check.
4. Ensure that the correct mouse driver has been installed onto the boot drive. Refer to the mouse
installation manual or the operating system manual.
5. Replace the mouse with a known good mouse.
If the problem persists, the system board may need to be replaced. Contact the HP Customer Support Center
for further troubleshooting assistance before replacing any parts.
