How can I hide the battery meter in Crysis?

I recently got Cryis (1) on Steam and there is a little battery meter reading "100%" in the top-right corner of the screen, even during cutscenes.

Apparently the battery meter is there because I'm playing on my laptop. Crysis runs on my laptop just fine, and I don't have a desktop PC that could run the game.

So, is there any way to hide or get rid of that "N/A ||||| 100%", at least during cutscenes? Thank you for your time.

It seems there are a few forum threads out there dedicated to this. The only success I've found so far is for Windows XP, here.
