Title: Err 80 ( how to remove Bios battery??)
Post by: Surely on December 13, 2012, 01:43:39 PM
Hello Guys,
lately I have had this problem with my 5d mark ii, camera turns on , nothing on the rear lcd screen. no access to menu or images.When i hit the shutter release mirror locks up and camera freezes. It must be kind of hardware issue but before taking it to a service I'd like to try removing the bios battery( or secondary battery as Canon calls it)  I read somewhere saying it could help to so.But I couldn't find where it is?
I know it has to be somewhere in the battery compartment but I couldn't find out. can you  please help.

Thanks
