macOS 偶尔唤醒时重启有遇到过的吗？

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？
