Identify the type and location of the noise
Listen carefully. Is it a squeak, grind, rattle, hum, or buzz? Where is it coming from — top, bottom, back, or sides? This tells you which component is the likely culprit.

Check for loose parts or foreign objects
Turn off and unplug the device. Look for anything loose — screws, panels, or foreign objects that may have fallen inside. Remove any debris you find.

Clean moving parts
Dust and debris on moving parts (fans, motors, rollers, belts) cause most noises. Clean all accessible moving components with compressed air and a soft cloth.

Check for worn components
Inspect belts, bearings, rollers, and fans for signs of wear. Worn parts often look shiny, cracked, or misshapen. These are usually inexpensive to replace.

Level and stabilize the unit
An uneven surface can cause vibration and noise. Make sure the device is on a level, stable surface. Adjust the leveling feet if available.

If That Didn't Work
- Try a hard reset: unplug the charger, remove the battery if possible, hold the power button for 30 seconds.
- Boot into Safe Mode to check if the issue is software-related.
- Check if an external monitor works to rule out screen vs. GPU issues.
When to Call a Professional
If the motherboard or GPU is the issue, repair costs can run $200-$500. At that point, compare with the cost of a refurbished or new laptop. If your laptop is over 4-5 years old, replacement is usually the better investment.
