Blackberry Tour Interference

I have noticed that when I set my Blackberry Tour down on my laptop, just to the right of the mousepad, that it shuts off my laptop.  Recently had to have my mousepad replace, which could have been due to this.  I'm thinking there was some kind of interference that caused it to go bad even though it wasn't directly placed next to it.  I also realized today that if I get an e-mail on my phone, while it is sitting next to the tv remote, it turns on the picture-in-picture on my tv.  Just sent a few more e-mails to myself to see if it was just a fluke, but it does it every time.  Cable guy is coming to look at the cable box today because it has been running slow.  Could this also be caused by the interference created by my Blackberry Tour?
