This article shows you what is the solution to the dormant power off of the Mac computer cover. The content is concise and easy to understand, and it will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Some partners have found that since their Mac was upgraded to Mojave, the power failure of the computer after closing the cover is very serious, and some partners may also have this problem if they do not upgrade the system. This may be because the sleep mode of Mac has been changed, and it only takes a few simple operations to save power!

The solution of fast power off when Mac computer lid is closed

You can view the hibernation mode of Mac through the terminal command, as follows:

1. Open the launcher-> other-> terminal

two。 Copy the following command: pmset-g, paste in the terminal window, and hit enter. If prompted to enter password, enter your boot password directly, the password will not be displayed, just input it directly, and hit enter after typing.

If you look at the hibernatemode line, if the number after hibernatemode is 0, then in this sleep mode, the degree of power loss is very serious. If the number behind hibernatemode is 3 (most people's computers should be in this sleep mode), the degree of power loss in this mode is generally serious. If the number after hibernatemode is 25, there will be less power loss (only a little bit).

So the way to solve the problem of power outage is to modify the computer's hibernation mode through terminal commands, as follows:

Paste the following command in the terminal window: sudo pmset-a hibernatemode 25, and then hit enter; if prompted to enter password, enter your boot password directly, the password will not be displayed, just enter it, and hit enter after typing

As mentioned above, if the number after the hibernatemode is 25, there will be less power loss, but there will still be some power loss, so if you want to achieve absolute power saving, you can also manually disconnect the network after closing the cover, or paste the following command on the terminal: sudo pmset-b tcpkeepalive 0, and hit enter. Similarly, if prompted to enter password, enter your boot password directly. The password will not be displayed, just type it directly, and hit enter after it. The purpose of this command is to set the network state when dormant to off. So if you want to download files after hibernation, this scheme should be used with caution.

Matters needing attention

1. After changing to the above two modes, in system preferences-> Energy Saving Settings, do not return to the default, otherwise it will return to the unmodified state.

two。 After modifying the above two modes, the screen startup speed may be slower after the cover is opened (the screen will light up for 3 to 5 seconds after opening the cover). If you mind this, you can choose not to change it.
