As Winter Approaches, be wary of heaters
A client of ours mistakenly left a space heater on overnight and came into work the next day to find the front bezel (front of the computer) had melted. The ports on the front, including power and USB, no longer function. This could have been a lot worse, with potential for fire.
This is a good reminder to double-check that everything is off before leaving for the day, and to make sure you leave ample space between your computers and heaters.
