Laptop Buzzing using USB 630m

AndyC · 7 Oct 2006 at 11:21

Got a Dell 630m laptop now not sure if I'm being pathetic but I get a slight buzzing sound from somewhere and it's only there when using the external USB such as a mouse - tried different mice etc,

It's not loud and can only really hear it late at night when all else is silent, so most of the time can't hear it, anyone else got this and is it just normal on these machines.

Cheers
Andy

you checked the battery

lol

could it be a slight buzz from the speakers?

or the actual screen?

Lol, not speakers (turned off) with or without the battery, maybe not a buzz vey high pitch, heard it on power supplies before now,

Only common thing is if the USB is being used,

checked dell for a bios update?

only thing i could really say would be electrical interferance noise from the mouse going through the speakers to be honest, even when mine are off i can sometimes get a buzz from my mobile and such through them.

Also know what you mean about the psu noise though on a pc, sometimes on my older rigs i could hear the psu change tone so to speak when playing games and such under load.

Weird one mate. :/

My dell buzzes when screen brightness is less than 100% (i.e. when on battery).
