If only you could hire an intern to jiggle the mouse every few minutes! And if you don't remember to undo those settings, your laptop's battery life will tank.įurthermore, some businesses don't allow employees to alter their PCs' power-saving settings, so you might be stuck with, say, a 30-minute time-out. Sure, you could monkey around with Windows' power settings, forcing the system to avoid screen-dimming, standby, and other power-saving modes - but that's a hassle. Why does this happen? Because Windows hasn't logged any mouse or keyboard activity, so its power-saving settings kick in. Or you step away from the PC for an extended period and come back to find it locked out or in standby mode. We've all been there: You're watching a video or running a slide deck, when suddenly the screen dims.
