HP EB645G11 R5-7535U 14 (B87GDEC) BIOS update error bitlocker

[croisade86]

Hi Team,

Please find the information for the following model:
HP EliteBook 645 G11 – R5-7535U, 14",  (B87GDEC).

The BIOS was automatically updated to version 01.08.01, but this version is not compliant and causes the device to request the BitLocker recovery key at every reboot.

Resolution:
Rollback the BIOS to version 01.07.01.

Hi @croisade86 

HP recommends that you always update the BIOS and disable BitLocker

Prepare your computer for the BIOS update

To prevent possible problems, close any open applications, and temporarily disable antivirus software and BitLocker before updating the BIOS.

1. Close any open applications.

2. Temporarily disable your antivirus software. In Windows, search for and open Security and Maintenance settings, and then click Security to access virus protection settings.

3. Temporarily disable BitLocker drive encryption. In Windows, search for and open Manage Bitlocker. Click Suspend protection, and then click Yes. Be prepared and have the BitLocker recovery key available.

   CAUTION: 

   If BitLocker is not disabled, the next time you restart the computer the BitLocker key might not be recognized. If you do not know the BitLocker recovery key, you might lose data or need to reinstall Windows.
