Enabling Bitlocker on Latitude E5550 makes Shutdown request Sleep instead
I'm starting customising my new Latitude E5550 laptop.
After turning on Bitlocker I noticed that when I shut down the laptop, it goes to sleep. Even if I logoff first then request a shutdown it still just goes to sleep. I can request a restart which does work - it restarts, but a shutdown still makes it go to sleep. I can hold the power button to force it off. Doing that or when requesting a restart, the laptop starts back up but I find that the laptop goes into Flight mode. The Flight mode symbol is visible even before you logon.
I turned off Bitlocker, and the problem has gone away. Is there a solution for this?
Should I use the Dell DDP Encryption product instead?
Thanks for any advice.

I have found a workaround to this problem. I have turned off 'Fast Startup'. This can be found in Control Panel / Power Options / Choose what the power buttons do / Change settings that are currently unavailable.
Now with Bitlocker enabled, my E5550 shuts down when I ask it to, instead of going into sleep and airplane mode when restarted.
The drawback is that it takes a little longer to start up from cold, but the difference is slight.
