Static noise (Ideapad 700)

Hello all,

 

My laptop : Lenovo Ideapad 700-15ISK (80RU00FEUS)

 

Barely even 2 weeks of ownership and it's starting to make an intermittent static noise mainly from the right bottom vent and both speakers whenever it's on.  Sometimes the noise is louder than the fan noise and other times you have to put your ear right next to those locations to hear it.  Extra static can be heard when moving the usb mouse.

 

Noise occurs regardless of :

* audio playing or not

* screen on or not

* adjusting volume or muting

* using speakers or headphones

* enabling or disabling playback and recording devices

* installing all latest drivers and updates

* power cord plugged in or unplugged

 

Any help would be appreciated, thanks.

Hi there, Lord             -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

You can also start by flushing out all static, remove battery and AC adaptor and hold down power button for about 15 seconds.

 

Update us how it goes.

 

 

 

 

 

Regards,

Yes. As per the Lenovo policy, the warranty will be void if the laptop is dismantled by yourself.

Could you confirm whether static noise coming from speaker?

 

Update us how it goes.

Re: Static noise (Ideapad 700)

maybe 30% of noise from speakers, 70% from right bottom vent

Re: Static noise (Ideapad 700)

Please remove the current audio drivers & re-install.

 

right click sound icon on the corner, select recording device > - default - microphone > on the listen tab make sure uncheck "listen to this device" and for the next tab make sure you select dc offset cancellation, echo cancellation and noise filter.

Control panel > sound > click sound tag > select sound scheme > no sound > “save as default” click ok.

 

Update us how it goes.

Re: Static noise (Ideapad 700)

1) remove current audio drivers & re-install : noise same

 

2) recording devices : uncheck "listen to this device", noise same

 

3) "Enhancements" tab

dc offset cancellation : no such option

echo cancellation : there's an "Acoustic Echo Cancellation", checked it, noise same

noise filter : no such option

 

4) sound theme : no sound, noise same

I am having the exact same problem.  The noise stops if I disable the Realtek audio device but then of course there is no sound on my machine.  Did you ever find a solution?  My notebook is only 6 months old.

Re: Static noise (Ideapad 700)

Hello: I'm having the same problem on my Ideapad 700 15ISK purchased 10 days ago. I followed all the recommendations and I have not been able to solve it for the moment. Any more recent ideas? Thanks.

I brought my Ideapad into a Lenovo repair center and they had to replace the motherboard. Thank god it was still in the warranty period.
