Hello, I have a HP17Z-CP220 and the screen is black with date and time flashing. I have gone in to the help menu to fix the problem but it asks for the recovery key. Any help would be greatly appreciated.

Hi @ken8177,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

Thank you for explaining the issue clearly. A black screen with date and time flashing on an HP laptop typically means the system is stuck in BitLocker recovery mode or a BIOS/UEFI recovery environment. When it asks for a Recovery Key, it’s referring to the BitLocker Recovery Key that protects your drive.

Here’s how to resolve this:

Step 1: Understand What the Recovery Key Is

• The BitLocker Recovery Key is a 48-digit numeric key.
• It was saved when BitLocker was enabled - usually in one of these places: 
  • Your Microsoft Account online.
  • A USB drive you saved it to.
  • A printout or file you stored.
  • Your organization’s IT admin (if work laptop).

Step 2: Retrieve Your Recovery Key

1. On another device, go to: 👉 HP PCs - Using BitLocker and finding the recovery key (Windows 11, 10) | HP® Support
2. Sign in with the same Microsoft account used on the laptop.
3. Find the key matching your device name.

Step 3: Enter the Recovery Key

• Type the 48-digit key exactly as shown.
• Press Enter to unlock the drive.

I hope this helps.

Take care and have an amazing day!
