Full Disk Encryption (FDE) primarily protects data when the computer is turned off or locked. If the laptop is booted and left unattended without being locked or shut down, the encryption does not actively protect data at the moment. Anyone who gains physical access to the device during this time can view and access all open data and applications until the computer auto-locks or is manually locked.

Exact Extract from Official Document:

'Pre-boot Protection requires users to authenticate to their computers before the computer boots. This prevents unauthorized access to the operating system using authentication bypass tools at the operating system level or alternative boot media to bypass boot protection.' This implies that once booted and logged in, the data is accessible if the laptop is left unattended and unlocked.
