I noticed my D7000 would not turn off its top LCD, the one next to the shutter release button.

Later I found that it was due to one of my SD card not working properly.

Apparently, before it turns off the LCD to display the number of remaining shots, the capacity of SD cards need to be read properly.

If one SD card is faulty, it will take a long time for detection, or give up trying, before switch off the LCD. In my case, it took few minutes.

Has anyone seen this problem?

I may be mistaken but I believe there was a thread about this several months ago; basically said what you have experienced. You might can go to the search box located in the top right to see if you can find it. Good luck.

Just to clarify for others, my power off issue occurred with and without the battery grip, with and without a lens, and both at the original time of the error and still continued an hour later when I got home.

To resolve the issue one of the following worked:
-removing the battery and both memory cards
-reseating the membory cards
-replacing the same battery
-reformatting both memory cards in camera

I'm not sure exactly which of these steps provided resolution but I am guessing it was reseating Card 1 card since it did not record any images from the shoot.

I was out shooting again this morning and had no problems.

I experienced the same problem. Top LCD on but camera was in reality off, nothing worked. I then noticed that the top LCD was indicating that the second memory card was highlighted although I was positive card #1 was empty. Could not access card one in the camera. Put card #1 in my card reader and formatted it in the computer then put it in the camera and it did recognize the card. Reformatted in the camera and no problems since. One shot problem. I'm assuming the card somehow became corrupted but the formatting in the computer somehow solved the problem.

In Lynda videos for the D7000, the instructor highly recommended format the card AFTER copying the photos to the camera.

Am I getting this righ?? Is it actually ment to go off then...When my camera is off it always shows the amount of pictures and the cards slots in use? Should this be the case? Thanks in advance

Regards

When it is off the card slots icon and number of possible frames for the card will show.

no, the display shows focus mode, shutter speed etc.

Sorry. I think I made that a bit misleading my comment...The display shows all the information when the camera is switched on and you are using it but what about when you switch it off. Does it show anything or also go off? Becasue that might draw a little bit from the battery. Is there a setting for this?

Regards

you may simulate this fault by putting a micro SD in an adapter loosely...

Hi
Greetings!

Is it better to keep the battery out of the camera while not using it?

Only if you do not want to use it for more than a month.

After six months, you need to set the date and time again, read the manual.

Try using a Meike AA battery grip if you use it a lot, visit the forum on D7000 battery grip.

Open and shutting the lid of battery compartment too much could cause damage and collecting dust too.

While that's probably true, it's pretty unlikely. The forums don't reveal many (any?) reports of failures from overuse of the battery door. I have cameras whose battery door has been opened on an almost daily basis for years with no ill effects. It's not something I would even consider when deciding how to manage my batteries.

Totally agree with that.

That is certainly not something I would worry about

Alkaline cells (AA batteries and the like) are susceptible to leakage, which is why manufacturers recommend leaving them out of the device when not in use. That doesn't apply to the Li-ion batteries used in Nikon DSLRs. I've never heard of one leaking.

But you probably should remove it once a month or so just to recharge the battery. The battery discharges slightly while in the camera both by self-discharge and because the camera is taking a very small amount of energy from the battery. In extreme cases, leaving the battery discharged may shorten battery life.

That said, I've left my EN-EL3 battery in my D70 for months on end without recharging it, and it's still working, almost nine years after I bought it.

Use NiMH cells then, please, or Lithium cells.

Although Li cells seldom leak, I have seen a bulging cellphone Li-ion battery, pushing the compart lid outwards.

In case of a Nikon, it could crack the plastic wall, so take the battery out if you plan to store you camera away, following the instruction manual.

A radio controlled helicopter instruction manual recommends not to leave Lithium ion battery discharge completely as it could damage the battery.

Lithium battery could burn and cause damage. Boeing DC-10 or 787
had some issues with their Lithium battery and crashed, causing hundreds of casualties, leading to order from FAA to ground all aircrafts of the same model.

Nikon may know the issues of managing Lithium batteries. However, in 2012, they recalled some batches of Li batteries because of risks related to excessive heat.

The report on this website:
http://www.engadget.com/2012/07/11/nikon-d800-d7000-battery-recall/

mentioned about 'burn hazard' of batteries for D800 and D7000
because of manufacturing faults.
