Having speakers emit static or crackling noises is a very annoying issue to deal with, especially when you don’t know what’s causing the static. The problem could be a multitude of issues, including magnetic interference or the cables not being plugged in all the way. Even a laptop brand as reliable as Lenovo can have issues. Here are a few basic things you can do to stop hearing static through Lenovo speakers.
Check the Cables
First, make sure everything is plugged in correctly. This is the most overlooked problem which takes 2 seconds to solve. Unplugged or loose cables can cause static interference if they are not plugged in all the way. Check your speaker cable, which is usually on the back of a desktop or the side of a laptop, and push it in. If you want to, you can take the cable out and wipe it with a soft material before plugging it back in if it is dirty. Check to see if your wires are tangled with any power cables as well, as this can cause electrical interference. Untangle them if that’s the issue.
Shielded vs. Unshielded Speakers
An interesting fact you may not know is that speakers have magnets inside of them. These magnets can interfere with other electronics, so computer speakers are usually shielded to prevent this. However, if your speakers are unshielded you may need to move them a little further away from your monitor to prevent this interference.
Volume Control
Check the volume settings on your computer, and check to see if the levels are maxed out. The Volume Control is located in the Windows Control Panel under Sound. If the volume settings are set too high, this can cause static, because the sound coming out of your computer is too loud for your speakers. Balance the volume control so that the volume is not too loud for your speakers.
