1. Can't restart or shutdown after installing the HP 9100 series writer software on Windows 2000 Pro?
2. Why is my keyboard not responding?
3. Why is my mouse pointer moving erratically?
4. Why doesn't my sound card play any sound?
5. Why isn't my microphone working?

1. Can't restart or shutdown after installing the HP 9100 series writer software on Windows 2000 Pro?
 Appearantly the software provided by HP is not compatiable with Windows 2000 Pro. To fix the shutdown problem just uninstall all HP writer software provided with your HP 9100 series writer. You might want try a third party writer software such as Adaptec Easy CD Creator Deluxe or contact HP.
 
  
2. Why is my keyboard not responding?
 If the keyboard is not responding (none of the keys are working), perform the following steps:
  1. Reboot the system to see if the problem disappears.
  2. Boot to a known-clean (non-infected), write-protected DOS diskette such as a bootdisk or diagnostic disk.
  3. Test for the problem in this environment.
  4. If the problem is no longer evident, troubleshoot your software.
  5. If the problem persists, proceed with the next step below.
  6. Shut down the machine and reseat the keyboard connector.
  7. Bypass any keyboard extension cables.
  8. Verify the integrity of the keyboard cable.
  9. Check for bent, broken, or missing pins on the keyboard connector.
  10. Test the keyboard in the mouse port.
  11. NOTE: Not all systems allow swapping the mouse and keyboard ports.
  12. If the keys are now working, the keyboard port may be defective; troubleshoot the motherboard.
  13. If the problem persists, continue with the steps below.
  14. Remove all external peripherals from the back of the computer except for the keyboard and the monitor.
  15. If possible, try another keyboard on the system.
 
  
3. Why is my mouse pointer moving erratically?
 

Through normal use, a mouse will accumulate dust, lint, and oils on the internal rollers. This will cause performance to slowly degrade. If the mouse pointer begins to move jerkily, or the mouse itself no longer moves smoothly, the mouse probably only needs to be cleaned. To clean the mouse, turn off the computer and perform the following steps:

  1. Under the mouse is a ring that circles the ball. Twist the ring counter-clockwise to remove it.
  2. With your hand under the ring and ball, flip the mouse back over and the ring and ball will fall out.
  3. Clean the ball by blowing any lint off and gently wiping it with a lint-free cloth if it has oil or residue on it.
  4. Inside the mouse you will see three rollers, generally one small white roller and two long black rollers that are perpendicular to each other. Carefully blow out any hair or lint.
  5. The rollers may have hair or lint wrapped around the axle points, carefully remove any lint with tweezers.
  6. Look in the center of the roller to see if there is any excess residue around it. This can be easily dislodged with a pair of tweezers. A cotton swab with a drop of rubbing alcohol can be used to get the roller completely grime-free.
  7. Once you are sure the rollers are completely clean and that there is no more lint, hair, or grime in the ball cavity, put the mouse ball back in and put the ring back on. Turn the ring clockwise until it clicks into place.
  8. Clean the mouse pads or feet if needed so the mouse slides as smoothly as possible.
NOTE: Keeping your mouse pad as clean and dust-free as possible will slow down the build-up process. Plastic mouse pads are better than the cloth ones as the cloth mouse pads trap oil and coat the ball with oil and lint. If you have a Optical or Laser mouse and the cursor is moving eratically then try it on a plain white piece of paper or a solid color surface (JUST NOT RED). It could be as simple as the mouse pad. If you have a cordless mouse the batteries.
 
  
4. Why doesn't my sound card play any sound?
 
  • Verify speakers are working and turned up, connect speakers to an alternative source if possible.
  • If computer has integrated audio, verify audio is enabled in the computer setup.
  • Set Volume Control, midway on all levels, and verify volume is not muted.
  • If there is still no sound, verify if any hardware or software has been installed prior to error. If hardware or software was installed, uninstall and test sound card.
  • If there is still no sound, remove all multimedia devices from Device Manager and reboot computer.
  • Verify that all multimedia devices were installed and test for sound.
  • If there is still no sound, rename win.ini file to win.old, and copy the system.ini file from the backup directory to the Windows directory. Reboot the computer.
  • If there is still no sound, remove all multimedia devices from Device Manager and turn off the computer for 20 seconds and reboot.
  • If applicable, clear NVRAM, either by jumper on the system board or in the System Setup. Check online documentation on a particular computer to learn how to reset System Setup.
  • Reseat sound card and test sound again.
  • If there is still no sound, the sound card may need to be replaced.

    5. Why isn't my microphone working?
     
    1. Verify microphone works by connecting a working microphone or connecting microphone to a different computer.
    2. If the microphone works, set Volume Controls midway on all levels, and verify volume is not muted.
    3. Verify the sound card is working.
    4. If the microphone is still not working, remove the all multimedia devices from Device Manager and reboot the computer.
    5. Test microphone.
    6. If the microphone is still not working, remove check mark from Multimedia under Setup tab from the Add/Remove Programs in the Control Panel.
    7. Reboot computer and check Multimedia under Setup tab from the Add/Remove Programs in Control Panel.
    8. If the microphone is still not working, remove all related multimedia devices from Device Manager and shut the computer down.
    9. If applicable, clear NVRAM, either by jumper on the system board or in the System Setup. Check online documentation on a particular computer to learn how to reset System Setup.
    10. Test the microphone.
    If all fails the sound card may need to be replaced.
     
      
    6. If my printer is plugged into my external Zip drive that is plugged into my printer port, why does the printer not work when the Zip drive is off?
     You need the Zip drive to be turned on so the LPT port on the Zip drive will be recognized. If the Zip drive is not plugged in, you will not be able to print.
