Macbook problem
Someone on my breed specific forum who is located in USA has posted about a Macbook problem.
There was a smell of burning and on investigation the magnetic connecting lead had smoke coming from it (where it meets with the little box with the bigger lead which plugs into the socket) and it actually burst into flames
When it was reported to Apple they dismissed it and said it was wear and tear, a bit too dangerous for my liking.
I wont be leaving mine plugged in unattended.
