This is both a computer related question and a camera forum question. Where to start??

I have a Canon 40D DSLR camera that I bought approximately 10 years ago. I took 6 pics with it, then had to leave photography alone- just no time… till now.

I charged the battery (have 2- charged both), they appear to have charged- went from 1 blink on the charger to 2 rapid, then 3, then solid. BTW, when I was ignoring the camera for all those years, I did pull the battery out, left the card in though.

I put the charged battery in the camera…turned the cameras switch to ‘On’ and…nothing. It won’t even think of powering up. The CF card is inserted, but I think I off-loaded pics years ago using the computer, and the card may be unformatted. I have 4 different card readers built into the face of my Dell XPS8000, the various drives (USB card readers) show up in Device Manager and in My Computer, but I can’t access a card that is plugged in to format it- it says ‘no media.’ The card, when inserted into the computers card reader, does light up as being recognized / active.
Halp!!

A 10 year old, completely unused battery..yeah, you need a new one.


It doesn't even THINK of powering up. I'll try a new battery, even though it took 45 min. to show charged..

Thank you

Solution
It turns out I must have had battery seating problems. The third time removing and dropping the battery back in, it fired up. Perhaps ever so slight oxidation on the battery compartment / battery contacts from just sitting all those years? Beats me, but works fine now.
 
I keep getting this suggestion. I appreciate people trying to help, but... I'm not sure people are understanding what I'm saying. There apparently was a minute layer of oxidation either on the battery contacts, or the camera's battery compartment. By dropping the battery in several times, it
broke through that film. It works fine now; in fact both batteries I have work fine now. There's certainly no reason to replace these now; the problem is solved.

Sometimes a card in your computer will stop working. Is your first inclination to buy a new computer? Of course not. You remove that card, and rub the contacts with an eraser, and re-seat it. Why? Because a thin
film of oxidation is stopping the card from making proper contact.

Your car isn't quite as shiny as it was several years ago. Throw it away and buy a new one? Or do you simply use a car polish and remove the...er...oxidation that has built up on it.

Thanks to all! 😀

...and you can't mark your own post as the solution? Brilliant.
 


No, you cannot mark your own post as the solution. It is designed that way.
As far as a new battery? Sure, it works. I'd be surprised, though, if it actually holds a charge in any way similar to what it did when new.

Take any rechargeable battery. Let it sit on the shelf for a decade. Charge it up and use it.
How long does it last?
 


I understand what you're saying.

Both batteries were fully charged May 15, and the one in the camera shows still fully charged. It hasn't been used though. So all I know is that it's holding a charge, not that it might deplete itself more rapidly than a brand new one.

I've always subscribed to the, "if it ain't broke, don't fix it" theory. :na:
