It's not a catastrophe, of course, but it is annoying. And it's even possible that your laptop won't reconnect to the projector after waking back up, which can quickly become a serious problem. One solution is to change the sleep settings in Windows' Power Management Control Panel, but that's a pain as well. And you don't want your laptop to avoid sleeping all the time -- just when you're projecting. I've got just the thing.
Mouse Jiggler is a small, free utility that keeps your computer from going to sleep. In essence, it jiggles the mouse for you, preventing sleep from kicking in.
You can use Mouse Jiggler for any sort of activity when you want to watch the computer screen completely hands-off for long periods of time -- like when watching videos or reading -- but I've found it's ideal for preventing sleep while delivering presentations. There's even a Zen jiggle mode in which the mouse doesn't really move at all (but the PC thinks it does). Groovy. [via Download Squad]
