Question about Nikon Coolpix 3200 Digital Camera

Nikon Coolpix 3100

Having now made my Coolpix operate correctly I'm puzzled by a residual battery current when the camera is switched off. Opening the battery cover and, with the camera switched off, metering across the exposed battery ends there is a significant current pulse flowing, at a rate of around one per second. Not having an oscilloscope handy I can only see it kicking my meter (set to its 100mA range). While some current flow is necessary to keep the clock running I would expect that that would be only tiny. As I'm concerned to know whether this battery drain is normal for the camera I'm inviting anybody with a 3100 (or a 3200) and who might want to help, to meter their standing current and tell me what they find. Thanks, Mog

    The current drain is not caused by the memory.  Removing the card makes no difference.

    You're absolutely right: CF card in or out makes no difference. Using a digital current meter it's difficult to determine the precise nature of the drain, as the pulses alias with the DVM sampling. Peak current I measured was c. 2mA; mean perhaps 0.5mA?

Similar experience, I could put a set of batteries in and have them last half a dozen pictures. I also put an amp meter across the battery terminals and then a scope and saw spikes of more than an amp when the camera was off. I purchased a 1350mA LI-ION battery pack for the camera and now it will take 3-5 pictures on a charge. The battery terminals get so hot that they will burn your finger if you touch them after the camera shuts down. There is a serious problem with this camera. I thought that the problem was the flash charging circuitry but it drains the battery even with the flash turned off or with the memory card removed. It has drained batteries since day one but the problem has gotten worse over time. No solutions here.

I had a problem with my old card with being unable to retrieve the pictures on it- so I thought it was the card. However I ordered a nes card and it now says out of memory , there are not any pictures on this card and i am unable to take any.

It is the SD memory.  Take that out when you are not using the camera, and it will draw less power.

Having gone over a month with no response, I assume this is no longer a problem.

Nikon Coolpix 3100 will not turn off or lense retract


Hi,

Try removing the battery from the camera to see if this will force a reset. This may well resolve the problem.

If your problem persists after this please do add a comment and I try to assist further.

Thanks for using FixYa.

Nikon Coolpix 2100/3100/3200 battery compartment door latch broken (again)


I just purchased a new battery door for $15 with shipping from nikon. They sent a simple assembly diagram and I was able to replace the door in 30 minutes. I used a dremel to cut the old door off, but you dont have to do that. I got a little impatient.

Just buy the plastic piece and u can reuse the metal parts for your old battery door.
