Will not turn on

Always charge batteries before using it for the first time, or if you have not used it for a long period. 3 months is a very long period.
Always charge sets of batteries (2 or 4) together.
Do not use alkaline batteries unless it is absolutely necessary. In some cases, alkaline batteries may have a shorter service life than NiMH. Alkaline battery performance is limited, especially at low temperatures. The use of NiMH batteries is recommended.
Never use manganese (Zinc-Carbon) batteries in electronic devices.
These batteries are only to be used in flash lights.

Check the contacts of the battery and in the battery compartment of the camera. They all should be clean and shiny. You can clean contacts with a dry cloth or cotton swabs. Never use anything sharp in or close by a camera.

as i do not know what laptop we are talking about here i asume its not a notebook
if it is the time is slightly lower (6-8 hours)
a normal lap top 10 - 12 hours.
some super batery laptops come with an own (long) guide how to keep the batery alive.

to keep the batery alive a long period of time charge it from 50% not when its at critical.

If u can take out the batery when you are using cable and its fully charged it also has a longer life time. or just take out the cable when its at 100% and recharge it when it gets to 50%

dont have your computer in the lap it can over heat the computer/batery and the lifte time gets even lower.

Green light indicates good battery strength. Red light indicates that your camera has an insufficient or low battery power level and will be automatically powered off. . To continue using the camera, please change your batteries to new ones.


Please note that:

1. If you don’t intend to use your camera for an extended period of time, please remove the batteries to avoid battery leakage and corrosion.
2. Do not mix old and new batteries.
3. Alkaline batteries are generally recommended.

Next time you get the camera to turn on, go into the menu and scroll to "reset" and follow the on-screen instructions.

Clean the battery holder with a pencil eraser, otherwise go for good brand rechargeable battery AA 2700 mAh try it.

Set setting to AUTO.
Charge batery or change batery.
Diract it to a lighted spot use external light.
set mode to power save and extend time to longer period.

Was your camera working before you put the new battery? if yes, then its possible some dirt or grit has got stuck between the lens and the body and therefore you motor might be warming up.

Since you 've bought a new battery, I dont think It may not be the battery, the way you are explaining. It could be the lens motor itself, since its warming up.

Try to do the following: ( I 've got this checklist from the forum itself)

Remove the batteries from the camera, wait a few minutes. Put a fully charged batteries back in and turn the camera on. if it doesnot work then,

2: Remove the batteries again, as also remove the memory card. Then install the newly charged batteries, when you turn it on it should come back to life.
3: Insert the cameras Audio/Video (AV) cable, and turn the camera on. Inserting this cable ensures that the camera's LCD screen remains off during the start process. Thus extra battery power is available to the camera's lens motor during start up. This extra power can be useful to overcome any grit or sand particles that may be jamming the lens.
4: Place the camera flat on its back on a table, pointed at the ceiling. Press and hold the shutter button down, and at the same time press the power-on button. The idea is that the camera will try to autofocus while the lens is extending, hopefully seating the lens barrel guide pins in their slots.
5: Blow compressed air in the gaps around the lens barrels with the idea of blowing out any sand or grit that may be in there jamming the lens. Other variations include blowing with a hair dryer in “no heat” setting, or sucking the gaps with a vacuum
6: Repeatedly tap the padded/rubber usb cover with the intent of dislodging any particles that may be jamming the lens. Other variations include hitting a side of the camera against the palm of your hand.

Try the above and let me if its any help.
Best of luck

I had the same prolem. OK, try this. Try to discharge the AA batteries in some use, flashlight or else,,,,then recharge them, full charge, install the batteriers ...they should work fine....
I read somewhere that canon is able free of charge to correct a shortcircuit that the camera is susceptible to develop in the installation of batteries......But I hope the advise will work...
Remove batteries when not in use.

Try replacing the date/time battery located in the main battery compartment. Also, simultaneously remove the lens. This will be like a master reboot for the camera. Replace the date/time coin battery, the main battery (freshly charged) and lastly the lens.

If this doesn't work, send it in for service. If you are just slightly beyond your one year warranty, Canon may allow a grace period especially if you can provide a receipt. If you can't find a receipt, give them the approximate date of purchase when you send in the camera. You will need to call them or set up service online.

Hope this helps!

just use recharchable bateries and if u don´t use the camera take them out, and u are right this cameras just drain batteries out, use a powerfull rcharcheble batteries, over 2000 mAh
