Battery Fully charged but camera says no power

It sounds like your power switch is defective since both power sources fail.

Hello Ice,

Please check the battery of the Nikon Coolpix 4100 Digital Camera. Please check the battery is fully charged or may be its damaged if its swollen. Also check the contact points of battery and camera and clean it. Insert the battery and charge it fully. When the battery gets charged fully then press the power button 4 to 5 times to start it. If the battery is damaged then replace the battery with new battery.

How about cleaning the battery contacts in the camera first with a pencil eraser and then, with a cotton swab lightly dampened with rubbing alcohol.

SOunds like your battery is bad. try discharing it :

1. Place the battery in your camera until it itself turns off. In this situation, the battery is fully discharged.
2. Take out your battery and slide it into your battery charger.
3. Connect your charger with power to fully charge the battery. It is normal for a new battery that battery indicator shows 100% capacity in 10 to 15 minutes. Please keep charging until there is no time left for charging.
4. Fully charged and fully discharged or "cycled" as much as five times to condition them into performing at full capacity.

Try it and see if it works? If the batteries are not rechargeable then the problem is in the cameras power supply and you need to take it in or replace it.

My old Panasonic Palmcorder IQ shows a red light in both switch positions-camera and VCR. Maybe yours has red for camera and green for VCR so you could tell them apart. I found that the Panasonic battery that came with the camera was the cheapest kind with the least charging time. I bought other batteries, they were good for a while, but now, many years later, they won' t hold a charge. Since I am only recording inside of my house, I have resorted to using the AC wall socket for power. I have to take the battery out of the camera. I found a power plug-in hole (like ones on cell phones) in the battery compartment. I also found one of these holes on my battery charger. My camera came with a double ended power plug. I plug one end into my camera and the other end into the battery charger. I plug the charger power cord into the wall outlet, and I have power to my older camera. Maybe you can find this double ended power cord at a store or on line.

Did you know that there are 2 kinds of batteries? Some have memories and others do not rely on a memory. The ones with memories have to be fully discharged or they will only charge a little, and keep charging less and less each time they are charged. The ones without the memory can be charged fully without being discharged fully. Check into battery information on line to get more information. Maybe you can get the non-memory kind.

Hi,

Possible causes and how to handle them
1. The camera is not on

Turn on the camera. (Operation procedure varies between camera models. Please refer to the camera user guide supplied with your camera.)


2. The rechargeable battery is not fully charged.

Make sure the rechargeable battery is fully charged. If the battery has not been used for an extended period of time, or if it is being used for the first time, it may not be fully charged. In cases like this, fully charge the battery and then discharge it completely in the camera several times to bring the battery back to its normal performance.



The rechargeable battery's capacity diminishes the longer the battery is used. When the battery consumption becomes quicker, the battery life may be at its end. Replace the battery with a new one.


3. The battery terminals are dirty.

When camera does not operate with a brand-new alkaline battery (for cameras that use AA-size batteries) or with a fully charged rechargeable battery, the terminals may be dirty.
Polish the terminals with a dry cloth and make sure the terminals are clean. If the terminals are covered with oil from your skin or similar matter, this may cause poor contact and power may not be fully supplied to the camera.

Also, polish the battery charger terminals with a dry cloth before charging the battery. If the terminals are covered with oil from your skin or similar matter, this may cause poor contact and the battery may not be fully charged.


4. The batteries are not installed correctly (for cameras that use AA-size batteries)

For cameras that use AA-size batteries, multiple batteries are used in one camera. Make sure the direction of each battery matches the direction indicated on the camera. If any of the batteries are improperly inserted, the camera will not operate.


5. The battery cover or CF card (SD card) slot cover is not securely closed

Most cameras have a lock mechanism on the battery cover. The camera will not turn on if the battery cover is not locked or securely closed, or if the CF card (SD card) slot cover is not securely closed. Make sure these covers are securely closed.
