The batteries are dead on my N65, but when I pushed the button that pops the flash up, nothing happened. Wondering if that is because of the batteries or if the flash is stuck/broke?

try changing the keyboard because switch is on keyboard and use adapter to plug and test

is the battery ok then try pluging with adapter directly

If you tried to reset it and nothing happened, the battery may be dead. This happened to my daughter's Garmin GPS twice. I replaced the battery and bingo! I never understand why the unity needs a battery even when connecting it to the car's power cord...

In the PSAM modes the flash won't pop up on its own. In the AUTO and vari-program modes, you can set the flash mode by turning the command dial while pressing the flash sync mode button (marked with a lightning bolt symbol). Select Flash Cancel (lightning bolt in a circle with a slash through it).

Find handset works by causing the handset, or handsets to beep when you push the button on the base unit, and until you find the handset and push the off button. If the handsets do not beep the batteries are probably dead.
We have a handset that flashes "Charging", and later, "Connecting", but it never connects. When the handset is removed from the charger the handset shows "Place in charger". By process of elimination I have determined that the handset has a problem. The problem is NOT with the battery OR charger. I hope this info helps you.

see if you can test the camera with another battery , you may be able to borrow one from a local camera store

Sound to me like you just need to replace the battery pack. Radio shack is a great place for phone batteries. If not, try www.batteriesplus.com
Good luck.

You might not have your lens set to the minimum aperture setting (the largest number) if it is a non-G lens.

Can you remove the battery? If so pop it out and leave it out for a couple of minutes then pop it back in and see what happens.
