Troubleshooting

If you encounter issues with your HP All-in-One PC, refer to the following common troubleshooting steps:

  • Slow Performance: Close any unnecessary applications running in the background. Check Task Manager for processes consuming high CPU or RAM. Ensure your storage drive is not full. Run a disk cleanup.
  • Keyboard or Mouse Not Responding: Verify that the keyboard and mouse are properly connected to the USB ports. If they are wireless, check their batteries and ensure the receiver is plugged in. Try connecting them to different USB ports.
