For MacBook and Windows laptops
Clean MacBook and Windows laptop speakers with sweeping tones, then finish the grilles with a soft brush.
Turn your volume all the way up, then press Start.
Which speaker plays?
How does each range sound?
Listen for rattling, crackling or a range that drops out. Many phones have a single loudspeaker, so left and right may both come from the same place.
Laptop speakers sit behind grilles that collect dust from desks, beds and backpacks.
Unplug headphones and disconnect Bluetooth so the sound plays from the laptop itself.
Keep the lid open and tilt the laptop so the grilles face down or to the side.
Turn the volume up and press Start. The sweep covers the different resonances of larger laptop speakers.
Brush the grilles gently, then run Left and Right in the speaker test to check both channels.
A liquid spill on a laptop is different from a wet phone speaker. Liquid can reach the keyboard, battery and logic board, and running anything while it’s wet risks a short circuit.
Use this tool afterwards only if the laptop works normally and the speakers still sound muffled.
It loosens dust in the grilles and in front of the speaker. Larger laptop speakers respond well to the Dust shake sweep, followed by a soft brush.
High, but not distorting. If the laptop speakers start crackling at maximum, back off a few steps.
Sometimes. If crackling stays after cleaning and also happens with quiet audio, check for driver or enhancement settings, then consider a repair.
