Apparently, my company has a security policy that states that if a laptop's battery dies (that is, uses up all charge because it's unplugged), the laptop gets locked and a domain administrator has to unlock it before it can be used again.
Is there anything to this policy that makes it more secure than not locking the laptop so a user can start using it again right away after plugging it in?
This is a highly secure environment, internal storage is encrypted and there are several security tools running on our computers all the time.
Edit: I didn't realize this could be relevant so I haven't added it before, but we're allowed to shut down / reboot the machines any time. We can also take them home to work from home (using VPN and IT-approved tools to facilitate authentication).
Edit 2: the computers run Windows 8.1 and are all part of a corporate domain. Access to various domain resources is tightly controlled.
