One afternoon as I was lying on my bed browsing the internet, my MacBook Pro suddenly turned off. I turned it back on and within a few seconds there was weird hissing sound, followed by white smoke and thin flames coming out of from the back.
I got up and ran with the laptop for the bathroom where I could put it on the ceramic tiles. Not more than ten seconds had passed and already the heat from the bottom of the laptop burnt my middle and ring fingers so badly I had to let it drop. Just in time.
There was a bang as I backed away causing the back to pop and smoke kept pouring out. It kept sizzling for a few minutes and then finally it stopped.
The house had filled up with smoke everywhere, the acidic stench of melted plastic made my eyes water.
After I had opened up all the windows in the house and cleared out the smoke, I removed the back plate to observe the damage and hopefully see if the hard disk had survived.
Didn’t look like it:
The source of the problem (battery pack):
The fire melted the entire right side of the motherboard/fans:
The battery swelled up about an inch as you can see from the shadow cast on the other battery:
It took almost an hour to cool down as the heat this thing had generated was insane. This was what the backplate looked like afterwards:
My fingers blistered and took almost a week to heal. I couldn’t use a keyboard during that time either (which being a programmer was a problem).
