Question about Nikon Coolpix 7900 Digital Camera

1 Answer

Sigh no sign of life?

I took some photos earlier today and removed the battery and put in the charger. When I put the battery back in it won't power up and acts like it has no power. I tried all three of my batteries with nothing. I was hoping this would last for the rest of the year so I can get something a little better next year.

Micro SMD Fuse blew on the board, needs to be serviced and that may not be worth the camera, but high end cameras are worth it, maybe yours. I could look at it for you, just the round trip price of postage. pishta68 at hotmail dot com

I have a brand new Nikon D3100. The battery was fully charged and placed in the camera. I took about 4 photos, and then turned the camera off. When I turned it back on the battery wasn't working to...


The solution to your problem is simple, Kathrynbax.


The battery never comes in fully charged. It's always charged only so you may be able to check if your camera is working. I suggest, you take out your battery and put it to charge for exactly 90 minutes as the manual says. Then I'm sure you won't face any such problems.


Hope this solves your problem.

Good day!

My battery for canon camera 550d flashes orange when charging, its been 4 hours now and it hasnt turned green yet.. I am charging it first time.. is this normal


Okay what happens sometimes is the charger gets into a feed back loop. What to do is remove the battery unplug the charger wait a few seconds (Maybe 20/30) plug the charger back into the outlet and then put the battery back in the charger. It should start to charge again and a few minutes later go to the blinking for full charge green.

It'll happen the other way as well meaning if the battery gets a memory (they say they don't but they do) you need to unplug the battery let is sit till it's cool and put it back on charge again. I've had this problem many times and have put it on charge and back off several times with in 15 minutes before it started to charge as it should.

Also these batteries do have a life span and if it's a three year old battery with many charges it could be failing meaning it just won't take a full charge.

I have a new refurbished kodak easyshare c160 -- the camera will not last but for one or two pictures without completely draining the batteries. i have tried about 4 new sets of photo batteries....is this...


Solution: As digital cameras become more advanced and include more features, the power needed to keep them functioning has also increased. That means that typical alkaline batteries likely won’t do more than power your camera for a few shots before running out of juice. Sometimes, your digital camera may not power on at all if the inserted alkaline batteries aren’t fully charged or powerful enough. Rather than carry along dozens of alkaline batteries for a single photo shoot, you can save money by purchasing rechargeable NiMH (nickel-metal hydride) batteries. Rechargeable batteries can be purchased with a charger that you plug into a wall outlet, and they fully charge in one to five hours depending on the charger and the type of batteries you’re using.

If you’re already using rechargeable batteries but are experiencing short battery life with your digital camera, it’s likely time to replace your rechargeable batteries with new ones. Depending on the number of charging cycles you perform (how many times you discharge and recharge your batteries), rechargeable batteries typically last for two to three years before they no longer hold a full charge. You may also ensure that you’re charging your rechargeable batteries directly before use. As batteries sit unused for extended periods of time, they automatically lose some of their charge.

There are many ways you can conserve battery life while using your digital camera, too. For starters, if your camera has a viewfinder in addition to an LCD, use the viewfinder to frame your shots and turn the LCD off because LCDs draw a lot of power. If you prefer to use the LCD, you can still conserve battery life if you refrain from looking at each picture on the screen after you take it.

Some Panasonic cameras only work with Panasonic batteries...part of Panasonic's plan to dominate the world! Is your replacement battery an off-brand?

Whatever you do DO NOT FORMAT the card. Take it in to a CAMERA shop, not walmart or drugstore, They can probably remove the card and print from that. Sounds likeyour card is full. They can then put all your pics on a CD and you can then reformat the card and use it again.

Battery life


Hi, Yes, there are both possibilities - either the camera is faulty and drains too much power from battery or the charger is faulty and can't charge the battery enough. How long does it take to "charge" the battery - from the moment you put the battery into charger to the moment it will signalize battery full? Do you have any friend with the same or similar camera? Try using your battery in his camera or recharging your battery using his charger. If not, try your local store if they will allow you to charge the battery in new charger... BTW it is normal for these batteries to have significantly lower life in very cold temperatures. The advise is to have the camera (or just battery) near your body so that it is not in cold for all the time and put it out only for time you take photo.

First, make sure you are using the right type of battery. LiMh re-chargeables are the best to use.  Brand is your preference. In time you'll find a brand you like the best. Get 1800mAh or larger if you can.

Second, look through the menu on the camera and check to see what battery "type it is set for.  "Alkaline" for self bought, Ni cad for rechargeable. This tells the camera how to regulate the power from the batteries.  Also using the wrong off the self batteries will give you the same result you mentioned.  Make sure it is for "photo" or "cameras".

Third, look into the battery compartment.  Look to see if there is any contamination on the brass/copper contacts. A "green" color is a bad sign.  Can be cleaned with baking soda and a tooth brush but very difficult.  Steel wool wrapped around a cotton swab works but leaves behind small particles (desperate method).  Also, sometimes they put a plastic liner inside the battery compartment to protect the contacts during shipment.  Is it still there?

Fourth, maybe the battery charger is faulty.  It may show the batteries charged but they are not.  Try using another charger.

If all these items I have mentioned are OK and check out, then there is really no other simple fix you can do as a consumer and you need to take the camera back. It is an internal problem.  You have had it lees than a year so it should be covered by warrentee.  I'd push the issue if they say "no"

Good luck and please let me know if this solved you problem, thank you..
