最後稻草，如果DELL電腦拒絕開機，專家會讓你做這些

如果機器在保，你打電話可能他們會讓你完成這些步驟。如果出了保修期，這些步驟是花錢送修前的最後稻草。有些組合鍵，還真是第一次學到。這些步驟可能對正常使用出問題的機器有效，對物理損壞或進水估計就沒戲了。

前一段與機器人的對話隻留了最後一步。前麵的省略是各種常規操作大部分人都會嚐試下（如電源線、撥電池）。

Please connect the AC adapter or charger, and then press and hold the power button for 30 seconds. 
The following video demonstrates how to reset the RTC: 

 

Note: When the AC adapter or charger is removed from the computer during the reset process, or the power button is pressed for less than 25 seconds or longer than 40 seconds, the RTC reset will be aborted.
