MBP Problem with External Display

[machomer]

I have my mbp plugged into the power and connected to an external display. Once I unplug the power, the display stops displaying.

The mbp is closed the entire time. I open it to wake it up and close it. The password unlock screen shows. I enter the password, but the display goes out and doesn't come back on.

Is this normal?

Apple's laptops will not run in closed-lid mode if they're not plugged into the mains.

Well, that explains it.
