Help with Shutter Speeds for Nikon D5100?

So I want to take a VERY long exposure photo.Is there a mode where I can press the shutter release button and just walk away so it keeps my shutter open for about 10 mins? I'm not talking about bulb mode, in which i hold it down for that length. I want to walk away and sit somewhere else while my camera is working its magic. Thanks

I have a Nikon D800 can you help?

On the D800. The on/off switch question. The switch has three setting, off, on, and a light bulb symbol. What does the light bulb symbol mean and what is its function? Can not find it anywhere in the owners book.

My Nikon Speedlight sb-700 keeps flashing Low Battery?

It would flash "Low Battery" even when I installed fresh ones. I haven't had a chance to use it much but I've bought it over a year ago so the warranty has expired. If it doesn't flash "Low Battery" then I would be able to use it 3-4 times and start flashing "Low Battery" again.

Where can I send it to have it repair? I've used it less than 100 flashes.
Added (1). I'm using the AA battery from Costco. The brand is Kirkland. Would this cause it malfunction?
