I have an Apple powerbook g4, and my original power adaptor broke. So I bought a new one online, not an original mac one as they are too expensive for me! But this new one makes my tv, stereo and even the sound from headphones plugged into the laptop buzz or go funny. I don't really have a major problem, I can handle the buzzing, but is this a health problem? Like weird electro-magnetic cancer causing stuff?
attempt plugging your audio equipment right into a various outlet then the laptop. If the setup worked advantageous until now the audio equipment have been attached then I say the priority is interior the audio equipment not the VGA cable. sounds like some thing desires a splash extra protective or diverse floor loop. you will desire to wrap the VGA cable in foil to be certain if that helps, i understand that sounds spectacular, yet whilst it does help, then you definately would desire to discover an audio or video cable with extra effective protective.
Electro magnetism over the short term doesn't harm you very much, but i'd be worried about the voltage that's going into your battery because mac products dislike anything that isn't made by a mac certified manufacturer... which is one reason why i NEVER use a mac product... cause they suck =P
your future u must reach a problem that your battery will be damage or dead cos the adapter have the circuit and done currect power plan of laptop so dont use the un authorised hardwares that cause ur system damage or dead and the vendors donot have any responsibilities for ur computer
