Chosen Solution
I’ve had my Nikon D90 camera for a few years now and have not used it in a while. Recently, I wanted to take pictures so I attempted to power it on, but it would not turn on. I tried to recharge the battery, but the device would still not power on. What could be the problem?
There could be a few things wrong with your camera. First remove the battery pack and check the compartment for any dirt or debris that may be blocking or covering the connections. clean it out and try to restart your camera. If that does not work the battery may be dead. For more information visit here
