Dear Lifehacker, Like many other Lifehacker readers, I have the usual collection of cordless power tools that don’t get used quite as often as they should or I’d like. I’ve read that keeping the battery pack constantly charging is no good for the battery. Can you recommend a strategy for ensuring the cordless power tools have the power when you need them but maintaining the battery life? Thanks, Cordless and Powerless
Windows: We all know your screen is one of the biggest battery drainers on a laptop, but some laptops don’t have a built-in button that puts the display to sleep. This little app will do it for you.
