(G1S-A1) Buzzin noise on highend reciever from laptop, goes with the hardrive activity

When i plug my asus g1s into something of quality, audio quality that is, it seems to pick up like electronic buzzing. When i move the mouse it kind distorts, when i open something it clicks with the hard drive, it almost sounds like a ground from something like the cpu or har drive is conected to my audio out. Honestly, ive ruled everything i could. Ive even tried to mute the on board mic to see if it was minutely picking up a signal but no. Im quite irritated and mad that i cant listen to music.

BUT HERES THE IRONIC TWISTY. When i unplug the ac power from the laptop, the sound is cleaner than a fresh copy of xp. uh oh this is where i get really mad, because this is the way it works.

Any ideas?

 

Sounds like electrical interference. Not sure what you could do about it, except to ensure that you plug the G1S in a socket with proper grounding; or else, remove the grounding pin using a 3-prong to 2-prong adapter. A ground loop could cause this sort of problems, I think.

 

Well its not only me who has the problems, its a huge majority of the g1s's. ill try pluggin it in without the ground prong. Thanks

 

You are awesome, i taped the ground off and it fixed the problem. omg im going to give you rep if i can

 

Umm... be forewarned, that's defeating the purpose of having the ground -- to protect against catastrophic failures in the event of a ground fault or short.

You probably have some sort of ground loop happening in your system somewhere. IF it is a ground loop, you might want to look into some sort of isolation transformer:

Scroll down to "Humming noise when I connect my soundcard to my hifi system".

Otherwise, it might be simply electrical noise from the charger if the IC for the sound card is located near the charger or on the same voltage references.

 

Yes, sorry about that, I should have cautioned that you actually remove the grounding pin which can cause problems in certain instances.

However, no ground is better than faulty ground, I guess, so...

For instance when I use a grounded plug in my (bad grounding) connection in my bedroom, I can almost turn on a lightbulb on the case of my V6J, I get so much residual current... if I remove the grounding pin, it's much better.

Needless to say I prefer to use a good grounding socket whenever available.
