If you didn’t replace your recalled laptop battery, here’s a video demonstration of what could happen. PC Pitstop forces a laptop into the same kind of chain reaction that led to various Dells and Apples catching ablaze, and initiated the largest product recall in the history of the world.

They try to test the heat using a remote thermometer (like the one mentioned in today’s Morning Deals) but the temp is so high, the instrument gives an error code. This means the temperature was over 1000 degrees Fahrenheit.
