• An AppleScript to Toggle Sleep Modes

    I have a 2008 unibody MacBook Pro, and the battery is starting to show its age. When I leave it in sleep mode, I maybe get a day and a half before the battery is completely drained. Putting my laptop into hibernation keeps the battery charge longer, but takes longer to start up as well. Depending on what I’m doing with my laptop (i.e. putting it to sleep at home for a few hours vs. traveling with it) I like to change the power mode accordingly so that I can go longer without having to plug it in.

    You can change the power-down mode from sleep to hibernate and vice versa using the pmset command line utility, but I kept forgetting the options to pass in, so I wrote a little AppleScript that does it for me. The script prompts you for your admin password, checks the current sleep mode, and gives you the option to toggle the other mode if you want to.
