Has anyone used your desktop without your permission? Have you ever returned home to find that your computer is turned on, when you specifically remember turning it off when you left? Would you like to learn a cool little trick to have an invisible switch, so others would not be able to turn your PC on?
The video by hanzablast below explains how you can install a “safety” switch, so you would only be able to turn on your computer by using a magnet.
This cheap trick shows you how you can install such a method. Now, if my Dad attempts to use my computer without my consent, the on/off switch would not power up the computer. The computer would stay intact and ready for work, but would simply not turn on. It would only operate if I place a magnet by the power button, as I press it.
Since this hack involves opening the computer and wire cutting, use at your own discretion. It seems easy enough and really inexpensive (four dollars or so), but it would really suck if I misplace a magnet; then I wouldn’t be able to turn on my own desktop. I guess it would also not work, if my Dad saw the video as well…and has his own magnet…
