Know What Happens When You Put Your Mac to Sleep
Putting your Mac in sleep mode is such a common occurrence that few users give it much thought. They assume that sleep conserves the battery and lets users pick up where they left off. Apple supports three versions of sleep—Sleep, Hibernation, and Safe Sleep—each with its own benefits and drawbacks, but few Mac users know which version of sleep their Macs are using. Understanding the ins and outs of putting Macs to sleep can extend the lifetime of your laptop computer.
Change How Your Mac Sleeps
All MacBook models since 2005 use Safe Sleep as the default mode. You may find that Safe Sleep is just what the doctor ordered. On the other hand, if you want to conserve the most battery life over long periods of sleep, another option might be better. After you know about the three sleep modes that Macs support, you might want to change to a different mode. Use Terminal to change how your Mac sleeps.
Customize the Energy Saver Preference Pane
Customize the Energy Saver preference pane to control the energy use of your portable Mac. With its easy-to-use interface, you can manage when your Mac should be put to sleep, when its hard drive should spin down, when the display should turn off, and a wide range of additional power-saving options, depending on your MacBook generation, including Power Nap on newer MacBooks. On some models, you can also use the Energy Saver preference pane to schedule when to start, sleep, shut down, or restart your Mac.
Calibrate an Older Mac Notebook Battery
Modern MacBook, MacBook Pro, and MacBook Air computers come with built-in lithium polymer batteries, which can only be serviced or replaced by an Apple Authorized Service Provider or a technician at an Apple Store. Most older Mac notebooks come with removable batteries that you can replace. MacBooks, MacBook Pros, and MacBook Air notebooks released since mid-2009 do not require calibration. However, older laptops can benefit from being calibrated. On these older MacBooks, the battery processor manages the battery performance and predicts how much time is left on a battery charge. To perform its prediction magic, the processor needs to know how well the battery is performing and how long it is taking to deplete from fully charged to nothing left in the tank.
Reset Your Mac’s SMC
Resetting the System Management Controller (SMC) on your Mac may be the solution to many problems you encounter with your Mac laptop. The SMC is a small piece of hardware that takes care of a group of basic housekeeping functions to keep your Mac’s performance up to par. If you have problems with the battery performance of your MacBook, MacBook Pro, or MacBook Air, experience sluggish performance, or encounter sleep issues, the SMC may be able to get things working correctly again. Calibrate your older MacBook, Macbook Air, or MacBook Pro battery when you first acquire your Mac and when you replace the battery, as well as at regular intervals to keep the information current. The process of resetting the SMC should return your portable Mac to tip-top shape. After you reset the SMC on a pre-2009 laptop, recalibrate the Mac’s battery.
Spin Down Your Drive’s Platters to Save Your Mac’s Battery
The Energy Saver preference pane is an easy way to manage your Mac portable’s battery performance, but one place where being easy to use is a drawback is when it comes to controlling when your hard drives should spin down. The Energy Saver preference pane suggests you “Put hard disks to sleep when possible.” What is lacking is any control over when the hard drives should be tucked into bed. Should they be put to sleep when the display is turned off? When there is no activity for a set amount of time? And if so, what’s the right amount of time to wait before the drives are put to sleep? Putting your Mac’s hard drive to sleep takes you through the process of setting the inactivity wait time before the drives say “goodnight.”
