Solution to Fast Power Consumption when cover up Macbook


更新了新系统就有这个问题,用终端,pmset -g可以调出电源设置参数,可以参考以下做修改,如果觉得不合适,可通过界面设置默认值调回来:

1、$sudo pmset -a hibernatemode 25

设置电池模式下的休眠模式改为25,原值应该是3。

2、$sudo pmset -a tcpkeepalive 0  

休眠的时候会tcpkeepalive,每一个小时会唤醒一次来保证查找定位mac的功能, 电池模式下的tcp唤醒关闭,影响是 “ Warning: This option disables TCP Keep Alive mechanism when sytem is sleeping. This will result in some critical features like 'Find My Mac' not to function properly.”
