how to turn on macbook in clamshell mode

I'm not convinced that there is a saving to be made by running the battery by day and charging over night, versus leaving it plugged in all the time. I'm not sure why Mac laptops are like this, but I'm sure there's a reason. If you want to run it off the battery, you'll have to open the lid.

keep the MacBook on when the power source changes?Īpple laptops have to be plugged in to work in 'clamshell' mode (closed, with an external display).

wake the MacBook when it is on battery power?.

Clearly, I do want it to sleep when I am inactive, but I have just been trying everything!Īll other (non-Apple) laptops I have had will simply switch to battery when they lose mains power, without interrupting you. I have set the power settings to 'never sleep' wherever I can see it and have enabled 'Prevent your Mac from automatically sleeping when the display is off', but still it sleeps when I turn the power off. I want to continue using the laptop regardless of whether it is switching from battery to mains or from mains to battery.Ĭurrently, whenever I turn the mains off, the MacBook goes to sleep and I cannot wake it with the external wired mouse and keyboard.

To save a small amount on the power bill, I would like to run it from the battery during the day and charge the battery at night when electricity is cheaper. I primarily use my Mac Book with the lid closed and connected to external keyboard, monitor and mouse.
