Z560 Headphone Static?

Ok so this laptop is about a week and a half old and I've already had a couple problems with it. But this one is bugging me the most. 

 

Whenever I have the laptop connected to AC power, there is a static/buzzing/beeping noise through my headphones if I have them plugged in through the headphone jack. It isn't loud but it's extremely frustrating during slow songs, quieter parts of songs, or if I am watching a movie that has a part without dialogue. The best part is that when I unplug the laptop, the static completely goes away. I have researched it immensely, but the only solutions I have seen say that there is something wrong with the laptop itself (so I need to get it replaced) and others say that I should take off the third prong on the AC adapter...I honestly don't know what to do and it's really frustrating, so if anyone could help, I would immensely appreciate it. Thank you.

Re: Z560 Headphone Static?

could be driver issue; try to update drivers from lenovo first or you may need to flash bios update.

also, threads that may help you :

Re: Z560 Headphone Static?

I already did all of those things...nothing solved it. This laptop has multiple issues, I'm probably just sending it in for a completely new one.

Headphone audio interference on brand new Z560 - but only when plugged in

Hi, today my brand new IdeaPad Z560 arrived in the post - it all seems great, except for this rather large issue: whenever the laptop is plugged in and I'm using headphones, there is a nasty, loud static noise - almost like radio interference. This disappears completely when I unplug the power lead, but that's not really a solution because I have it plugged in most of the time, and the battery life isn't that great anyway.

 

I have tried disabling all sound enhancements, I've tried using a different plug socket, I've tried different headphones, updating drivers, everything I could think of - but nothing's worked.

 

I'm wondering if anybody else has experienced something similar, and if they have, do they have a solution?

 

Thanks,

Paul

 

Edit - I see my post has been moved to a similar thread, where it was left unresolved. I guess it's a common issue with this laptop - should I just give up and send it back for a refund? It's a shame, because I really did like it otherwise.

Ok, just flashed the BIOS update and it's not made any difference.

 

I didn't have this problem on my old laptop, so I can only think it's the hardware on this one.

i know your issue is not solved but due to you posted similar issue, i've just merged the threads.

can you perform clean windows installation by pressing one key recover?

it's up to you, to ship it back or ask for refund.

I only got this laptop today - surely I haven't done anything that warrants a clean Windows installation already? I've barely installed anything.

 

One thing I have noticed is that the distortion stops very briefly every time the computer is processing something, and fluctuates when I change to a different power plan. Very strange.

Yep, tried that. 

 

Think I'm going to try and arrange a refund, I have to act quickly.

 

Thanks for your help. This was my first Lenovo product, and probably my last.
