Their computer use from 2005. I do not want to leave it, but now it is sick very quickly run out of batteries. Despite his good new batteries replaced. I found out that the phenomenon is just a noise when turn on the radio equipment, including computer speakers. Signal interference from mobile phones to keep Express speakers such as the horse's hooves. Phone emits waves and their interference for the reason that it was out of battery fast. Before that, and in no other machines can not broadcast phenomenon such interference. Is there a way to cure my machine? Many thanks.
