只要運行它后，一旦網(wǎng)線被拔掉的話，馬上就進入自動關(guān)機倒計時，“-t 30”是倒計時的時間，你可以自己調(diào)整。
代碼如下:
Dim Wsh,objWMIService,colMonitoredEvents
Set Wsh = WScript.CreateObject("WScript.Shell")
Set objWMIService = GetObject("winmgmts:\. ootwmi")
Set colMonitoredEvents = objWMIService.ExecNotificationQuery("Select * from MSNdis_StatusMediaDisconnect")
Do While True
Set strLatestEvent = colMonitoredEvents.NextEvent
Wsh.run "shutdown -s -t 30 -c "&chr(34)&"系統(tǒng)網(wǎng)絡(luò)斷開，機器即將關(guān)閉"&chr(34)
Loop
