I used to have a Zen Creative MP3 player. I would hook up the audio output to an 1/8" stereo jack to the input on my car radio. I would do it while charging it.
It burned up the MP3 player after 1 hour. I thought that the power was somehow leading to an audio ground and that's why it burned out.
Do you think I would have the same problem with my IdeaPad A2107A-F
