Canon A310 Won't Power Up.

Coolpix Cameras are tricky to use with chargers. I will assume your USB Charger EH-69P is 100 - 240V 50/60 Hz so it CAN work in many places around the world with an adapter. Do not go over 240V or you could damage it.

These cameras like to have the power supply connected when it is on to charge - meaning if you have it connected and you plug the charger in the wall it will NOT charge. So if you plug the charger in the wall first and then plug the cable in the camera it will work. The camera is actually ON when it charges and I never REMOVE the memory card when it is ON.

When you have a dead battery. Plug the camera in and make sure the ON LED lights and the Charge LED flashes. Then don't mess with it. Let it charge completely (Charge LED stops flashing and is OFF) and then unplug it. It will turn off. Then later you can turn it on.

The power supply adapter may be dead, should be tested, if okay! remove the main battery will load player down in some cases. If still no result! cheaper to replace than repair.

if its completely dead buy a new power suppley. else its the motherboard that is defective. check your warranty first.
thinks you can test is to remove all your memory and bios battery then try to start

Remove the battery for at least 3 minutes... Then put it back and then plug in the charger and switch on the charger. If the battery is completely drained, it would take a while for the charging to initiate. Please have patience and leave it on charging even though without the charging indication for at least an hour. After that still if the charging indicator doesn't lit, then its definitely your charger or laptop. You will need to take it to a service centre in that case.

Things to check first for a camera that won't turn on are battery contact points, and micro switches that are located on the battery and memory card doors. Troubleshooting tips on other things that need to be checked may be seen here. These tips won't work for every case, but they're worth a try.

Hi there please follow the steps and let me know the result.
1. Ensure batteries are fully charged & clean the battery connector point in side the battery compartment.
2. Look carefully between the lens and the camera body for any sand, dirt or any damaged etc.
3. Try turning the camera with the lens facing down and shake to dislodge anything stuck
4. Try removing batteries and memory card, wait 5 minutes and refit the battery only.
5. Now turn on camera( with out card ) and see ,if working then fix the memory card & again turn on the camera. If working then fine . Otherwise format the memory card and fix back in camera again & try. Make sure before format the memory card take a back up all photos in your computer then format. If no luck then reset or restore the camera setting by pressing Menu key for 2 sec .. in not done the press both Menu & self time key for 2 - 4 sec.

My Canon SX100 IS doesn't power on. I tried using several batteries and also cleaned the metal battery contact but nothing works. Any advice ?

It may be the SD memory card causing the problem. I just bought a G7. When I turned it on without an SD card, no problem. I put it my old cheap SD card and it wont turn on. I take out the memory card and battery, then insert the Canon SD card and battery and turn it on, no problem.
Hope this helps someone.
