x200 audio static problem

I'm using thinkpad x200 and having audio static problem when listening using ear/headphone. It dissapear when i touch the metal part e.g. usb or vga port.

Due to this, I can't peacefully listen to music with annoying buzz sound throughout. Any helps appreciated. Thanks.

 

The analog out on the x200 doesn't have a particularly low noise floor but you are likely experiencing interference from the HDD/CPU or other components.

If you are using sensitive headphones or IEMs you will pick it up more.

 

do you use a dock?

 

@jaredy: not sure that the interference is from hdd/cpu or other parts, how to get rid of the interference?

@lead_org: no, not using dock

 

do you have the 3 pin ac adapter or those two pin adapter with no grounding?

 

hi lead_org, you are absolute right. Thanks bro!

I got static when using two pin adapter for outdoor usage (90w). But at home I use 3 pin (65w) and it just dissapear.

Is there a way to convert two pins adapter to have ground? Sorry for stupid question.

Thanks again.

 

Just call Lenovo and inform them of this issue (provided you are under warranty), they may send you the 3 pin adapter as a replacement.

Or just purchase a 3 pin one from ebay or something. You would have to strip the adapter apart to rewire it, which is not something one should do, unless you have necessary electrical engineering know how.

out of curiosity why do you lug around a 90 watt adapter for outdoor use, when you could just lug around a 65 watt one?

 

@lead_org: good advice, will contact lenovo on this, would fall in love with them if they can help me on this. I'm a retard in electrical thing, would definitely spoil it like any previously.

I carry the 90w around to help me charge up faster and sits 65w at home to help save on electrical bill

 

The 90w adapter doesn't necessarily use more power...

 

@jaredy: I see, thanks bro, I learnt new thing today
