I have a nikon D40 camera. I was taking pictures with my new puppy and he knocked it over onto the ground and now the automatic focus won't work. It will focus but it will not take a picture and the flash won't pop up. Any help??!!!

Re: Nikon D40 help?!
I assume the lens had the impact.
The 18-55 lens has the built-in motors for auto-focus.
Try switching to manual focus (on the lens). If this works, the lens may not auto-focus anymore.
Try it and let me know.

The letters you're referencing is the M/A (manual / auto) focus switch. The lens has this switch and operates in Auto Focus mode when set to "A" and manual focus mode when set to "M".
You have to manually focus on the subject when in letter "M". If you do not, the result will be out of focus. From your description, it sounds like the camera / lens combination is attempting to focus and operate the shutter in auto, and focusing in manual; but due to some type of damage resulting from possible mishandling, exposure to dust, dirt or even moisture is interfering with the successful completion of the process.
You could isolate the problem to determine if the cause is in the lens or camera by simply attaching the lens to another compatible Nikon camera or placing a different auto-focus lens on your D40. The problem will either stay with your D40 or follow the lens when attached to a different camera. It is also *possible* that due to numerous attempts of auto-focusing with your D40 & lens combination, that both the lens *and* the camera have been damaged. If the problem is severe enough, the problem in the failed device could cause failure in the otherwise normally working device, too.
You might be best served by contacting Nikon Service & Support below:
1 Possiable dirty lens contact terminals
2 Auto focus motor in lens is jamed/malfuntion
3 Auto focus engagement pin on camera body is not engaging the lens
4 Correct lens,old nikon lens and some 3rd party lens wont work on the D40
Camera wont let you take a picture until focus is locked, why are you using M (manual focus) if you expect autofocus to do it for you? In M mode it is up to you to focus correctly or camera will not take the picture.
When the camera is in auto focus mode, it will not take the picture until it locks onto a subject. If there is not enough light, the camera will "hunt" for something to focus on. Since it can't define any edges, it won't allow the shutter to release.
The D40 base model does NOT have a powered focus lever for autofocus, so if the autofocus is not working, suspect the lens.
