> The guy decided to turn it back on, which is when it blew up. Which is exactly what anyone else would do if their laptop suddenly shut off without giving any clear warning that the situation was dangerous. A proper safety system would need to notify the user of the possibility of a battery fire and advise them to take the laptop somewhere where fire damage would be minimized. But it's not entirely clear to me that safety features were actually triggered. Perhaps the battery failed and the machine shut down due to lack of power or a power fluctuation. The fire could have been inevitable at that point, and his actions after the shutdown and before the fire are just red herrings.
