Since a couple of months, my "out of warranty" D90 is having a problem. Even after shutting down the unit , sometimes (post of the time) the green led is blinking (at random speed) untill the battery is 100% down (after half a day). Anyone has an possible reason why this happens , or a 100% working solution. PS: D90, battery packs and charger are 100% genuine NIKON.
Switching memory card , or formatting memory card does not help.
Even without lens , problem occurs.
I tried also a other battery pack , same problem...
Regards, Rik
Possible that PC is hanging up as there is fault on the OS ( operating system) or a virus in the OS. Also it is possible that the back up( CMOS) has low voltage or the memory card is a suspect. In this case you need to check the voltage and also try and swap a memory card. If not the OS is a suspect.
It is also possible that the mother board is faulty but can be confirmed only after you ensure that the memory and power supply is good.
