  Dr. Katherine ScottAug 18, 2025
  If your Lenovo Desktop isn't starting up, first ensure the power cord is correctly and securely plugged into both the computer and a functioning power socket. Also, make sure the power socket is supplying power. If you've recently added or changed hardware, ensure it's correctly and reliably connected. If a configuration error appears, press F1 to enter BIOS and save the settings to exit. Finally, ensure the computer is turned on within its operating temperature range (10°C-35°C) and avoid immediate startup after moving it from a significantly different temperature environment; allow it to sit at room temperature for over 2 hours.

  If there's no audio output or only a single track after installing an audio card in your Lenovo Desktop, ensure the speaker or microphone connectors are properly connected, the speaker is powered on, and the volume is at an appropriate level. Also, verify that the audio card driver is correctly installed and that the audio card and player software properties are set correctly. In Windows XP, check the 'Enable Digital Audio for this CD-ROM Device' option in Device Manager, or select player software that supports digital audio.

  If your Lenovo all-in-one Desktop monitor isn't operating normally, and the screen is black, check that the power cable or adapter is connected to both the computer and a working electrical outlet, and that the computer is powered on. If the screen is black with only a white cursor, use one-key recovery to restore the backup file to the Windows environment, or restore the system partition to its original factory state. If a black screen appears when the computer is on, check if a screensaver or power management has been enabled by pressing any key, the power button, or switching from Monitor Mode to Computer Mode (if supported). If issues persist, the computer may need repairs.

Why is audio or video discontinuous on my Lenovo Desktop?
- R
  robert77Sep 4, 2025
  If you experience discontinuous audio or video when playing a VCD/CD on your Lenovo Desktop, the CD might be of poor quality, making it difficult for the computer to read. Try replacing the CD. If too many programs are open, close other programs or restart the computer, as this can strain the system's resources. Also, verify the optical drive's transmission mode is correctly set to DMA in the Device Manager's Slave IDE Channel properties under Advanced Settings; restart the computer after making changes.

  Colin TapiaSep 7, 2025
  If your Lenovo Desktop mouse isn't working correctly, ensure the mouse cable is properly connected. If it's a USB mouse, you can plug/unplug it while the computer is on. Clean the bottom of the mouse or the ball inside if it's dirty. For sluggish movement, ensure the desktop and mouse pad are flat and clean, and consider replacing the mouse pad, as different materials and colors can affect optical mouse performance.
