With the battery life of a laptop I take every possible help. The clearest sign that my MacBook Pro ages ($ 1,799 at B & H Photo-Video) is the inevitable fact that its running time is evaporating more and more, if not day after day, then month after month. It just does not hold a fee like it used to.
Powering the display is the biggest drain on battery resources, so I keep the brightness of the screen to a minimum (it's easier on my eyes too) and use the power saving settings to slow down the display on battery power and back to 5 turn off minutes of inactivity. Turning on the keyboard light is less of a burden on the battery, but there is a built-in setting that I recently learned about turning off the keyboard light after a period of inactivity.
Keypad Light Switch Off Automatically
The keypad backlight setting in Energy Saver mode does not appear in system settings along with the display settings (and standby mode). Instead, you need to go to System Preferences> Keyboard . On the Keyboard tab, select the check box Disable the keyboard illumination after ____ of inactivity . Your options range from 5 seconds to 5 minutes. I chose the middle selection of 30 seconds.
This setting not only helps keep the battery running longer, but also that the backlight of the keyboard turns on when I tap a button to continue working. I enjoy greeting my MacBook when it comes to life and comes back to life – much like my dog wagging its tail and circling circles as I walk through the door after 5 hours or 5 minutes.
