I need to buy a need one as every time i plug my ac adapter into my laptop it melts the ac adapter and i know that problem is not with the ac adapter as my brother has the same ac adapter and it melts his the same as mine and also both the ac adapter work perfectly and dont get hot when the battery is taken out, this must mean the problem is with the battery right? so does anyone know anywhere online i can buy one? with a UK style plug, i've searched myself and found nothing so far so maybe you can help
