D is for Dead, Dead, Deadsky

On Monday, my computer failed to project my lesson to my high-tech Promethean Board; so, I did what we're told to do: I turned off my computer. This would have been great had the machine turned back on. Nope. I poked, tapped, and held the button down for an insane amount of time, but the computer is dead, dead, deadsky. Luckily, I just backed it up last week. Even still, I lost part of today's lesson and had to hustle to rewrite it. Technology is great when it works, but when it doesn't . . .

Word of advice: 

BACK UP YOUR COMPUTER, NOW!
