Annoying scratching sound coming from Lenovo IdeaPad L340-17IRH 81LL003AMH

2019-12-07, 6:00 AM

Hello,

 

Last week I bought an Lenovo IdeaPad L340-17IRH 81LL003AMH laptop.

 

The latop is great but there is one thing that bothers me... Sometimes I hear a very annoying scratching sound. It's a very high tone coming from the latop.

 

Sometimes it's there continuously, and sometimes I only hear it when I move to mouse cursor on the screen.

 

It is mostly hearable when the PC fan switches on.

 

Is this normal?

 

Thanks for your answers.

 

Best regards,

JW

Hi JW82!

 

Welcome to the Community Forums!

 

Do you hear the scratch sound on your L340 when you boot up the computer or does this happen when it is already on the Operating System? 

 

Another question is it coming from the left side or the right side part? If you encounter it, could you share it to us by recording thru audio or video for us to conduct an investigation. 

 

Looking forward to it.

 

Regards,

Jerry_Lenovo

Hi Jerry,

Thanks for your reply.

The scratch sound starts when the fan is on.
When I'm doing thing on the pc (like writing a letter) when no resources are needed the PC is completely silence.

When I go to youtube and play a HD video the fan turns on and the scratching sounds starts.

It's on the left upper side.

Hope you can help me.

Jeroen

You can hear the fan but also the sound.
