ac adapter noise

i recently noticed my ac adapter making a beeping/humming noise that i have never heard before. at first i thought it was my hdd but then i noticed it when i pluged it in.my laptop is a cq50 210us that i got in november with the included charger and battery. i have read different things on various fourms ranging from the noise being normal for chargers to people saying that it could be the battery is going to fail. i am looking for a straight answer for what this sound is. if anyone could help me it would be greatly appreciated.

Re: ac adapter noise

well thats a relief, i am kinda surprised,the noise can be very high pitched and very notiveable when playing music. i also just noticed that it becomes louder when i change the power options from balanced to high preformance

Re: ac adapter noise

Hi, I have the same problem my ac adapter sudently started to beep, I know it has a noise when you plug it in, but it has never beep before. I'm sure that in not normal, because when the adapter is beeping, the sound is lound and the battery doesn't charge, so it's not normal. Any one know if it my ac adapter is going to die?, Any one solve the problem?, I think is a manufacter problem, but I'm not sure.

Yeah, same here. how could it be NORMAL when its not charging the battery. also noticed that for some plugs adapter beeps and doesnt charge, and when i plug it into some other plug, it works as if nothing happened. maybe variable voltage is the cause? my laptop is Presario CQ45-104TX.

in some posts i read its the ac adapter itself thats in problem, some posts say battery, and in some posts even say that its the motherboard failure that makes all the fuss.

so any suggestions experts?

Re: ac adapter noise

my ac adapter is making beeping sound since past one month, when it is beeping then there is no charging takes place. But after awhile it start charging. Now it is making the sound continuously, and not charging system. Do I need to change my Adapter or is there anyway to get it right.
