I've got a problem with my Asus X53S. When listen to music by headphones or speakers everything is okay (clean sound) a laptop use a battery. When I put a cable to charging I've got a noise. When I take out a cable everything is fine immediately. I use a standard audio out by minijack and checked on 4 different audio systems - the same result.

I tried to use a microphone out (after remapping), but it is the same.
I think it can be something like a clasp. Computer is after warranty period. Any advice?

Yes, laptop power cord have an earthing pin. I think that power source is properly grounded. I tried this in 4 different places (my apartment, my friends house, McDonalds, cafe) and it's the same. Unfortunately I don't have another charger to check it.
I use original ASUS PA-1900-24 (http://tinyurl.com/lnxn5zc).



Each plug is full in. Power plug and music output (minijack). When I partly pull out the power cable sometimes noise is changing for a second.

NOTE: Situation is the same when laptop is without battery, only on cable.
