Last month, Apple announced a recall of what it said was a “limited number” of older MacBook Pros. At the time, Apple explained that certain 15-inch MacBook Pro units contained a battery that “may overheat and pose a safety risk.” New images now offer a closer look at the outcome when that happens.

First spotted by PetaPixel, 15-inch MacBook Pro user Steven Gagne shared images of his laptop on Facebook, saying that it exploded just three days before Apple’s recall. Apple announced the recall on June 20th, and Gagne says his MacBook Pro exploded on June 17th.

In the Facebook post, Gagne explained that his MacBook Pro caught fire overnight:

Perhaps most interestingly, Gagne said that his MacBook Pro wasn’t in use at the time, nor was it plugged in and charging. He said one small move on his part likely saved his house from burning down due to the MacBook Pro fire:

Apple’s recall for the 15-inch MacBook Pro is considered voluntary, and the company says that affected units were sold between September 2015 and February 2017.
