Loud noise when closing lid

this sounds like the microphone is picking up feedback, if you are not using the mic then go to control panel then sound and disable the microphone

I’m happy to help further over the phone at https://www.6ya.com/expert/jonathan_828b54f422cbefdd

In Windows 7 ,Try the Power Options in Control Panel. Set to High Performance, select Change Plan settings, set Sleep to never, select Advanced Power settings, scroll through the Advanced Power settings, set Sleep and Hibernate to Never and Power Buttons and Lid to Shut down. Always shut down and unplug the Laptop when not in use to prevent damage due to a power surge and a possible Fire hazard IF the battery malfunctions. Not to mention unnecessary wear on the components.

Could be an alternator problem. Bad ground wire or just old bad wiring.
If you have an amp then the power wire is to close to the speaker wire.

Your laptop has a switch for turning on/off the mouse pad. Check to see that it is not off.

Could be a bad fan assembly.

Hello,

By chance have you tried making sure the laptop is not too close to the speakers? Sometime you will get feedback when the source is to close to high powered speakers. Also, check your jack cord and make sure no splits/cuts are visiable and the plugs are fully inserted.

Good Luck and keep making great music. Aloha.

Hi there.
Your microphone is on, and when you close the lid it is closer to the speaker. It needs
a loud noise (like closing the lid faster) and it enters into a feedback loop.
We need to find a way to make the microphone not play back.
Try left clicking on the speaker icon in the bottom right of the screen, and click playback
options. Here mute the microphone, and see if it solves your problem.

Good luck

the problem is in the motor itself, if you can lube the place where the bearing and the shaft is, this is where the sound came from
appreciate your kind comment

Freezer section evaporator fan motor bearing are going out. This would be indicted by a high pitched squealing noise. Have the fan motor replaced and it should solve your problem.
