Canon EOS 5D Mark II shows Err 80 or won’t wake from sleep

My Canon EOS 5D Mark II sometimes won’t power up normally. If I remove and reinsert the battery, it starts working again, but once the camera goes to sleep or I switch it off, the problem returns. It will sometimes display: "Err 80 – Shooting is not possible due to an error. Turn the camera off and on again or re-install the battery." I’ve already tried removing and replacing the clock battery, but that didn’t help. Is there a known fix for this, or does it usually need Canon service?

I've just got my camera back from repair and this was apparently caused by water damage to the DC-DC board, an expensive repair but I hope that my camera will now work well for some time to come! I've not yet worked out how the water got in - but I'm suspecting a damp camera bag after a seaside shoot.

Err 80 on the 5D Mark II is a general hardware/electrical fault, so there isn’t one guaranteed cause. From the reported fixes here, it can be linked to an internal board issue (including possible moisture/water damage), and in some cases it required Canon service.
One reset step that helped at least one user was:
- Turn the camera off.
- Remove the main battery and CF card.
- Close all doors.
- Turn the camera on and hold the shutter button for 30 seconds.
- Turn it off, reinstall battery and card, then power on.
If that only helps temporarily—or not at all—the body likely needs inspection/repair by Canon or an authorized service center. Since the problem returns after sleep/power-off, and replacing the clock battery didn’t solve it, a professional repair is the most likely long-term fix.
