Must Remove the battery & then reinstall it to get camera to turn on.

My Canon Powershot SX40 HS camera will turn on only once per battery insertion. i.e., put battery in, the camera turns ON OK. Turn camera OFF, then press the On/Off button and the camera will not turn on a second time. Take the battery out, put the same battery back in, press the On/Off button, and the camera turns ON and everything works fine again. Turn it OFF once more and it won't come back on until the battery is removed and then reinserted (same battery). I've also found that once the remove/insert battery cycle has been performed (i.e., camera now ready to turn on), pressing the Playback button will turn the camera on, just like the On/Off button does.

Larry Bishop, The battery or corroded contacts could be the issue. If you can clean the contacts with a pen eraser(has a little grit in them) or a Qtip dampened with 90%+ Isopropyl Alcohol, then blow all debri from battery compartment. Check contacts while at it for being bent down, damaged,etc any thing that could affect connection. Still not working properly, there could be slight difference in the battery from Canon NB-10L battery, perhaps purchase a new OE battery. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.

"A word on the CHDK software. Even though it loads via a firmware update, there are NO actual changes to the firmware. It is strictly SOFTWARE and resides on the SD card. It's a little tricky to get it loaded and operating the first time until you become experienced in the quirky procedure (locking the card, making the card bootable, etc.). I have CHDK loaded on all my Canon PS cameras, never a problem (unless you copy the wrong version for your camera, then it just doesn't come on until you remove the software from the SD card). It's really good SW, and also have a battery voltage indicator option which might help with troubleshooting.

One more thing- you can prevent the software from loading by simply unlocking the SD card and turning the camera back on.

Good luck!"
