Nikon D750 locked up (Page 2): I've seen that type of thing here many times. Remove the battery, put it back in, and the problems go away

Remedy.... removed the camera battery (not the MD bat) shoved it back in and all was good again. Anyone else have this happen?

I've seen that type of thing here many times. Remove the battery, put it back in, and the problems go away - sometimes.

We use cleaning alcohol, which is probably surgical spirit, and a cotton swab. The technicians did say this needed to be done more frequently if the body and lens are not stored detached when not in use, and if there is a long period between camera use.
I guess part of the problem is an assumption that these cameras do not require regular service, they are fine to be stored as is at the end of every shoot. A little care can go a long way toward keeping the kit in top shape.

I had the very same thing happen to me recently with my D750. I was in the middle of shooting a wedding using the 70 - 200 VRII and the camera just shut down. I am assuming it lost connection with the battery but I did the same thing - took out the battery, reinstalled it and never had another problem. I had my backup on my other shoulder so I was all set there but thought it was really odd. Hoping it is not a design flaw but I guess we will see. I was on a location shoot and the second shooters D700 did the same thing so not sure if it is a Nikon design thing.

My old D200 with over twenty thousand clicks on it, it has not have any problem yet, as well as my Df with over six thousand shutter clicks. I have never touch or clean those contact point. I always take off the lens from the camera when not using to avoid constant contacting between those metal points. It tends to erosion.

It happens on occasion with every digital camera I own. Same cure, remove battery, re-insert battery.

We had a D800 that this happened on too frequently to be acceptable. Took it to Nikon who cleaned the connectors on both camera and lens; resolved the problem.

Like all electrics there can be a build up on connectors that reduced the signal strength. We now regularly clean connectors on all our kit.

That makes the most sense as to cause. Amplifying the problem are all the additional contacts using a teleconverter and compounding tolerances of fit as well.

My 750 did this also right after I bought it, about nine months ago. Reboot remedy - same as what you did worked for me also. Has not happened since. I did do firmware upgrade about six months ago.
