Encrypting automatically my device (HP ProBook 450 G7 Notebook PC) with BitLocker failed. When looking in the Windows Event Viewer, I found this message that seems to me to be the root cause of the issue. 
Can someone help me ? 

The following DMA (Direct Memory Access) capable devices are not declared as protected from external access, which can block security features such as BitLocker automatic device encryption:

ISA Bridge:
PCI\VEN_8086&DEV_0284 (I/O LPC Controller - 0284 for Intel(R) 400 Series Chipset Family On-Package Platform Controller Hub)

 

PCI-to-PCI Bridge:
PCI\VEN_8086&DEV_02B0 (Intel(R) PCI Express Root Port #9 - 02B0)
PCI\VEN_8086&DEV_02BC (Intel(R) PCI Express Root Port #5 - 02BC)
PCI\VEN_8086&DEV_02B4 (Intel(R) PCI Express Root Port #13 - 02B4)
