(This is similar but doesn't address the fire hazard issue.)

I have a MacBook Pro with an 85W power adapter. My wife has a MacBook with a 60W power adapter.

We charge both computers with both adapters. Of course the MacBook Pro charges more slowly from the 60W adapter, but otherwise it's fine.

However, according to this comment, using the 60W to charge the MacBook Pro is a fire hazard!

Is this true? I am surprised Apple engineers would have made them interchangeable if this is the case.

But basically, what happens is on my MacBook (latest model) whenever I 'flip' a Dashboard Widget I hear a little noise for the duration of the flip: like a tiny continuous squeak noise. It's quite strange. However, it only ever happens when the MagSafe cable is plugged in. WHY… >>> More

Disclaimer: I've been a PC guy my entire working career. I'd probably characterize myself as a power user. Never afraid to bust out the console line. But working with a Mac is totally foreign to me. So for those Mac guys who are curious, this is how your world appears from the outside to a computer… >>> More

Leading up to the problem: I was working late one night on a Keynote presentation. My battery ran out, and the computer did that hibernation thing it does when there's no battery power. I got my charger, connected it to my computer, and then pushed the power button. It started up for a second in… >>> More
