disturbing noises while charging clevo m52

hi guys,

there are some disturbing noises while charging in my clove m52 after the charge is completed they stop even I continue using with external power. Or there is no voice if I charge the computer while closed.
it more likely a hdd voice but not sure but it can be heared by the next door so it's very loud.
does anyone have any idea? (we got 5 of the same laptop all of them have the same strange noises)

 

hmm that sounds strange.

its the battery healthy?
- do you always keep it plugged in?
- was is the current batterylife (how long does it take for a 100% battery to discharge)?
- have you tried to remove the battery and just use the external power?

 

thanks for the reply
- no I usually work with battery when finish I plug in
- the computer is brand-new I just bought it 5 days ago and it was the same noise with the first run. battery longs like 3 hours
- yes I have tried there is no voice.
the voice comes only when the battery is charging

 

when you say "voice" do you mean some type of "sound" coming from it?

have you contacted your Clevo reseller about this strange sound?

 

yes, I mean a very disturbing sound is coming of from it.
I contacted the reseller and they said all the notebooks from clevo has the same disturbing sound while charging so there is nothing to do.
We bought 5 of them at the same time all of them has the same sound.

 

No, all clevos don't do sounds when charging lol. Where are you located, i mean in what country? Could it be related to a different electric voltage from US or Canada? Could it be a very poor electric signal from where you're charging them? Do they have external speakers plugged into them?

 

I'm from turkey we are using 220 V, it's different from US and Canada they are using 110 v, but if the difference comes from thevoltage the noise should probably come from adaptor but it's coming from the front side of the computer more likely very close to hdd.
I don't have external speakers plugged in

 

it sounds like electrical noise.

i believe it could be just that particular model, or the voltage being too high/low due to the region and charge adapter type.

so the charger is the default one, or the one specifically for your region?

I would recommend to use an International AC/DC power adapter to plug the notebook to test it, its not much, usually under $20.
