Re: battery in wrong way
HATE TO BRING BAD NEWS, BUT THERE IS THIS THING CALLED REVERSE POLARITY. THAT IS WHEN YOU PUT THE BATTERY IN WRONG AND THE CURRENT GOES INTO THE CAMERA THE WRONG WAY AND POOF! ELECTRONICS GET FRIED! THEY ARE VERY SENSITIVE AND THEY USUALLY CAN'T WITHSTAND SOMETHING LIKE THIS. IF YOU HAVE TRIED A NEW BATTERY AND IT STILL DOESN'T WORK, COST OF REPAIRS WOULD BE MORE THAN WHAT YOU PAID FOR THE CAMERA. ALSO, DOING THAT TO A BATTERY WILL KILL IT TO OR CAUSE A FIRE, SO YOU PROBABLY WERE LUCKY TO GET IT OUT OR THAT SOMETHING ELSE FRIED FIRST, BEFORE YOU HAD A MELTDOWN. MOST CAMERAS ON UP THE LINE FROM THIS ONE HAVE SOME WAY TO BLOCK THE BATTERY FROM GOING IN WRONG. THEY HAVE A CURVED SIDE OR SOMETHING THAT WILL ONLY LET IT GO IN ONE WAY. POINT TO REMEMBER WHEN YOU LOOK AT CAMERAS. SORRY FOR THE BAD NEWS, BUT IT WILL SAVE YOU MONEY IN THE LONG RUN,ESPECIALLY IF SOME REPAIR SHOP GOT HOLD OF IT AND DROPPED A $150.00 REPAIR BILL ON YOU.

Several things can be wrong. The battery, the camera, the connection cord and the charger.
If you can measure the voltage of the battery, with a multimeter, try that. The voltage should be e bit more than what is printed on the battery. I think it should read 3,7 Volt. So the be sure the battery is still in working order, check if the multimeter gives about 3,8 or more. (after charging). Then the camera, If there is dirt on the contacts, or you managed to put in the battery the wrong way around, it won't work. Then the charger could be defect, or have bad contacts. Or the cord could be defect. Check all parts, if they are still clean, shiny, and nothing is bent.
The charger light should come on. If it does not, toy already have the culprit.
More than one possibility can cause this. Your battery can be on the end of life. Only when the battery works in another camera, of the same model, you can check the capacity. Or with a multimeter, but you must have some electronic skills. Then the contacts on both the battery and in the camera can be dirty or oxidised. Sometimes users manage to put in a battery the wrong way around. This should be virtually impossible with your camera. Try cleaning the contacts in the camera and on the battery, using some cotton swabs. Never use anything sharp.
Then again try charging the battery. Look if the charger light starts green. And is it stops after some time. If you already charged the battery, it could be the light goes out after a few minutes.
If the charger light starts flashing, you know something is wrong with the battery to the connectors. Don't forget to close the battery cover correct. There is a switch, and if the door is not locked correct this switch still indicates open battery door and the camera won't switch on. Check your manual page 17 and 18.
Could be the camera, but always first check the contacts from the battery and in the camera. Just to be sure nothing can block a free current. The contacts should be clean and shiny. Not a spec of dust is allowed in the battery holder. If you should need to clean the contacts, only use a dry cloth. Never use a sharp tool in or close to a camera. Then make sure you put in the battery the correct way. I don't know how strong you are, but sometimes people manage to put the battery in the wrong way around. Make sure the battery-camber / Memory card slot cover is closed correct. There is a little switch that indicates if the door is open or closed.
Almost impossible two batteries are dead at the same time. Unless you left them lying for a long time.
When you think everything must be right, just press the power switch several times in a row.
If nothing helps, I guess contact to a Nikon service station, or a new camera?
When this happened after you charged the battery, a few things can be wrong. The worst that could happen, is the battery did not survive the charging session. Other things:
You managed to put the battery in, but the wrong side around. Almost impossible, but I don't know how strong you are.
There is a bit of dust in the battery compartment. Just a little piece of paper can be enough to block the current.
The battery door / cover, is not closed correct. Every battery cover has a switch that is needed to inform the camera that the cover is locked. When the switch does not work, the camera won't switch on.
So my advice: remove the battery, Look if all contacts are clean and shiny. On the battery and in the camera. Check if the battery is really charged, by placing it again on the charger.
After reinserting the battery, check is the battery cover is closed correct.
If your batteries did not leak at all, and corrode th points where the. Batteries make contact, then it could be something very serious on the main board, or something simple like the on/off switch. Really it's the sort of problem that needs to be seen by someone. I'd check the battery connections first, then make absolutely sure the batteries are going in the right way around. Flat end is - and pointed tip end is +.
i had this problem also. i tried reinstalling the program on my computer, buying new batteries and charging them with an external charger. nothing seemed to work. i was convinced the problem lay with the camera. i had taken the camera at one point to a very cold and dusty environment (a glacier). the lens cap started getting stuck after that, and it would occasionally not send out the lenses. i had dismantled it to clean it, which kind of worked. this time, i was certain it was something to do with the recharging system in the camera. however when i opened it up i noticed 2 things... a) one of the 4 base screws that hold the battery cover on, had been put back in the wrong place... these screws are about a millimeter longer than the other black screws, and in the wrong place could have been shorting it out. b) the front and back covers are grounded by a strip of copper on the side opposite the strap retainer. these were crushed and could have been also grounding something out. i straightened the strips out and put everything back together, testing the on/off button after every couple of screws. i am happy to say that i got mine back working again. i put my experience down to inexperience and the difficulty of doing a field repair the first time. tools required: magnifying glass, bright light, and a very fine philips screw driver (1mm). p.s.: the lens caps still sticks partially closed, so i never did fix that problem. LOL!
