How many time has this happened to you? You are watching a movie or giving a PowerPoint presentation on your laptop and the screen dims and just goes black. And this doesn’t just happen once. This could happen every ‘x’ minutes, annoying you and others.
While it may be an annoyance, the computer is actually trying to save power by dimming the monitor when the operating system ‘thinks’ that you aren’t doing anything. Unfortunately, you computer isn’t intelligent enough to know that you are actually watching it. A jiggle of the mouse will restore the screen and an occasional jiggle of the mouse will prevent the screen from dimming. Another option is to change the power settings to keep the screen alive longer.
That’s exactly what MouseJiggle, a free tiny utility, does. Obviously it doesn’t actually jiggle your mouse physically. It simulates mouse inputs so you don’t have to mess around with the power settings. Just run MouseJiggle before you start your movie or presentation and click ‘Enable Jiggle’. You’ll see that your pointer starts to move back and forth. This tricks Windows to stay awake.
In programs such as Windows Media Player, moving the mouse brings up onscreen controls. During such times, enable ‘Zen Jiggle’, which causes the mouse jiggling to happen behind the scene with no actual cursor movement.
