So i was gonna post this up, just to give you people some ideas on what to do if you are in similar position.
While i was at the Newport aquarium last week, i had a nightmare happen. My camera started locking up. It started draining batteries, left and right. I was perplexed. I was frustrated, worried i was going to have to send it back to Nikon just days before i had 3 BIG shoots planned.
here's a video of the problem.. at 50secs, skip to 1:20.. Trisha dont video edit
Now for some of the simple solutions.
Discharged all my batteries- 2Nikon, 1 Chinese knockoff, and recharged them to full (the only way to do this, that i am aware of is to stick em in and use em till dead {thats what he said}, since they were mostly drained, i just stuck em in my D90 and ran em out on demo mode.) Formatted both my memory cards Reset camera to default settings
I dont know which of these solved the issue, but things seem to be in good working order now.
I will be sending it in to Nikon, for just in case purposes, but sometimes, simple things can help fix what might have been a big issue.
