My magsafe power adapter caught fire in the surge protector power strip, about 2 hours ago, at the site of the prong. I moved the power strip slightly, and the heavy adapter wiggled on the strip, zapped, shot out sparks and very small flames that extinguished right away after I removed it from the power strip, and poofed out a bit of smoke and soot all over the plug, the outlet, and the nearby plug for my iphone (which was fine, just soot-covered on one side). Thanking God that I was right there when it happened. Prior to this incident, the magsafe power adapter had no visible wear whatsoever, no fraying at the magsafe connection to the computer, no nicks in the length of the cord itself, and the adapter and plug looked new just like the cable cord and magsafe connector. My MacBook Pro is about 8 years old. The battery is practically shot, so I do keep the computer plugged. Ironically, I was just complaining about this computer at BestBuy today, while looking for an extension cable for the power cord (the one it comes with is frankly too short), because it has been a lemon from the start. I'm posting this in reply to Steve Trabajars' comment above, especially because there was honestly no visible wear at all on the magsafe power adapter, and the surge protector was less than one year old, again, clean, no visible wear. I reported this to Apple Support and was immediately transfered to a representative obviously trained for this kind of event, so there is a problem with these adapters, and you should pursue getting yours replaced via the website, and @Steve, report your Wisconsin store for not addressing the problem. Visual inspection of the magsafe/cablecord/adapter and plug means nothing, apparently, in my case.
