645 mirror stuck in up position

After some time I took my Pentax 645 to shoot some B&W's. But I found a problem. For some reason the mirror is stuck in the up-position and won't come down. The lever in the side does not do anything. Any idea what might be wrong, and what to try? I don't remember any issues after the last time I used this camera.

I may have to old batteries, but at the moment don't have new ones available. But batteries should not be an issue here, right?

While I don't have my manual handy I suspect the mirror gets stuck up if the batteries are dead. There's a key somewhere under the camera that you can attach on the left side to wind the mirror down (also advances the film and cocks the shutter). If you have a little battery juice left (the shutter is electronic) you can probably take pictures like this. Or maybe you only get 1/1000.

But really, just get new batteries.

(I'm assuming the lever you're talking about is the DOF preview lever, which isn't supposed to do anything with the mirror.)

I've had this happen before because of dead batteries. Didn't know there was a place to wind the mirror down or cock the shutter or advance the film.
My mirror was half way down, so i just flicked it down with my finger.

Thanks guys, and yes the battery seems to be the problem and the answer.
And yes the lever had nothing to do with the mirror, I use this camera so seldom I mistakenly thought it was the mirror up lever :-(
