Dell Precision 5530 2-in-1 Service Manual

即時時鐘重設

即時時鐘 (RTC) 重設功能可讓您從 No POST (無 POST)/No Boot (未開機)/No Power (未通電) 的情況復原您的 Dell 系統。若要在系統上啟動 RTC 重設,請確定系統處於電源關閉狀態,且已連接至電源。按住電源按鈕 25 秒,然後放開電源按鈕。請前往參閱《How to Reset Real Time Clock》(如何設定即時時鐘)。

註: 如果在重設期間將交流電源從系統上拔下,或按住電源按鈕超過 40 秒,RTC 重設程序將會中止。

RTC 重設會將 BIOS 還原為預設狀態,解除佈建 Intel vPro 及重設系統日期和時間。下列項目不會受 RTC 重設影響:
  • Service Tag (服務標籤)
  • Asset Tag (資產標籤)
  • Ownership Tag (擁有日期)
  • Admin Password (管理員密碼)
  • System Password (系統密碼)
  • HDD Password (HDD 密碼)
  • TPM On and Active (TPM 啟動與運作)
  • 金鑰資料庫
  • System Logs (系統記錄)
下列項目不一定會根據您的自訂 BIOS 設定選項重設:
  • 開機清單
  • Enable Legacy OROMs (啟用舊式 OROM)
  • Secure Boot Enable (啟用安全開機)
  • Allow BIOS Downgrade (允許 BIOS 降級)
