Mid 2015 MBP ,系统版本 Sierra 10.12.2 ,偶尔会遇到唤醒时重启的现象(最近一周内遇到两次),插电源和不插电源都有,中间休眠时间在一个小时左右。
具体表现是:开盖按键盘无反应,按 Power 键发现系统重新启动了,关键是启动后并没有任何错误提示。
查看 last reboot 发现确实有条 reboot 记录和唤醒的时间一致,休眠相关设置信息如下:
$ pmset -g
System-wide power settings:
Currently in use:
standbydelay 10800
standby 1
halfdim 1
hibernatefile /var/vm/sleepimage
powernap 0
gpuswitch 2
disksleep 10
sleep 1 (sleep prevented by coreaudiod)
autopoweroffdelay 28800
hibernatemode 3
autopoweroff 1
ttyskeepawake 1
displaysleep 2
acwake 0
lidwake 1
请问有什么办法能查到重启的原因吗?
补一段电源管理日志: 21:43 是我合上盖子回家的时间, 22:57 是我开盖的时间,也是 last reboot 记录的时间,奇怪的是在此 10 分钟之前(也就是 22:46 )居然有一些日志,这个时间点电脑应该还在包里呀,不知道重启与之有关吗?
