Stuck on change batteries

you might have cooked it..... fresh alkaline batteries carry a voltage of about 1.7v.
try turning it on/off multiple times to see if it will clear the fault.

Dear Tejas Belani,
I hope you're still reading this but I had exactly the same problem with the Ixus 255 HS as you describe (full battery - false message - filled battery icon when looking to pictures on the memory card).
After some failed rescue attempts (recharging, completely discharging, 10 second hold of on/off button), I think I finally found it: put a small piece of paper or carton in between the battery opening door and the battery. This pushes the battery a couple of millimeters deeper in the battery bay and ensures a good contact between battery and pins at the other end.

Seems like Canon were a bit cheap on the plastic levers that secure the battery ... or perhaps they erode after some time of usage. This type of camera is often exposed to more aggressive conditions than the bigger, more expensive camera's out there :)

The solution is very simple.
you are going to remove the battery (while this screen is on) as the command screen tells.
And your camera should function properly.
I tried it and it worked.

NB; Do not try to close your camera then remove the battery.
Remove it while the camera is still on.

Hello,

Your camera's problem is the lens itself. There is something making it stuck, this problem can't be repaired. Take it to Canon or a reliable camera store to get it fixed.

If you are familiar with camera repair then apart camera and check navigation switch board is intact with main board of camera.
That is only reason of switches no operation in this camera.

i have the same problem with these camera. to get it fixed just take out the battery wait for a few sec and put the battery back on, then switch the camera on. for the lens just gently move/force the lens to open, then turn off the camera wait for a few seconds then turn on the camera back on see what happens. and if still persist keep doing it till gets back to normal.
this sometimes happens to my camera from time to time i think it just its wear and tear.
one more problem with this camera is that it'll go blurr, just do the basic turn off or take out the battery wait a few sec and then turn it back on.
hope this will help u.

Problem connector,DC-IN part no.1-794-637-11

I have this problem as well. I thought it was a problem with my NiMH batteries. So, I bought a volt meter to make sure the batteries worked. I have 8 AA NiMH batteries. I charged them all up and tested them with the volt meter. They were all good to go. However, no matter what I put in the camera one of two things happens:
1. I get the "change batteries" message.
2. I don't get the message, but the next time I check the camera (a few days later), one of them is totally drained.
Something is very wrong and I plan on contacting Canon.

I am experiencing exactly the same problem with my Canon Powerhot S2IS. I tried the same thing to remedy it by cleaning off the contacts, but no luck. And it's not simply a cold weather problem. My camera does this with brand new Duracell batteries as well as with freshly recharged NMH batteries. What gives? I've had the camera for nealy 2 years and have taken excellent care of it.

Are you certain the batteries are good and fully charged. They do wear out eventually. Hopefully it's not a jammed lens causing the problem. Does the display come up with an error number or maybe even "lens error" before switching off? If it does it will mean a trip to the camera doctor. How far are you actually getting with the switch on? Try switching to view picture instead of the shoot mode. This consumes less power and if you can see the last picture you took on the LCD or even a flash of it before closedown I'd put my money on bad batteries. Make sure the battery ends are clean and the camera battery contacts aren't corroded or dirty. It's sometimes amazing how trouble a little dirt can cause. BMW
