各位，我想问一下，我在我的笔记本电脑上采用EFI+GPT安装Ubuntu 16.04 LTS系统，我点关机之后发现电脑关机后不到两秒钟就会自动启动，需要手动关机，我使用命令sudo shutdown -h now进行关机，也是先关机，但是过两秒之后电脑又自动启动了，这是怎么回事哈？

sudo shutdown -h now

試試
sudo systemctl poweroff
或
sudo systemctl --force poweroff

參見
http://manpages.ubuntu.com/manpages/xen ... ctl.1.html
systemctl - Control the systemd system and service manager
poweroff
Shut down and power-off the system.
-f, --force
execute the selected operation without shutting down all units. However, all processes will be killed forcibly and all file systems are unmounted or remounted read-only.

没有效果，还是关机断电后，自动开机

檢查一下
1. Bios 中 按下 poweroff 是設定什麼回應

今天发现一个问题，只要我在电脑的第二个usb接口插上设备，关机的时候，电脑就不会自动重启

BIOS中没有poweroff的设定，今天发现在笔记本的第二个USB接口插上设备时，可以正常关机，不会出现重启的情况
