Having problems with your Canon PowerShot A640 Digital Camera ?

My Canon A640 is eating batteries! I have tried 2 sets of rechargeable batteries, both 2800mAh. After an overnight charge these will give me 5 or 6 pictures before giving up. I would hate to give up on this camera, it's a great piece of kit but currently it's unusable! I would be grateful for any ideas. Many thanks


Answers :

I'm going to assume this camera is not new as the first review launch date was in 2006 and updated in 2007. If the rechargeable batteries are two years old my first suspicions would be that the batteries have acquired a short term memory. Contrary to what the manufactures claim these batteries do get "lazy" The problem stems from not completely discharging/exhausting the batteries before putting them on a charger. If the batteries are constantly drained lets say to have power then charged again they will eventually give you only 1/4 there power before the battery indicator shows exhausted. What I have my associates do now is put the batteries in lantern type flash lights and just kill 'em then place them on the charger. Yes i did have to triple the amount of batteries in the fleet BUT now instead of getting six months out of a set of batteries we now have gotten two years. Also there are new types of rechargeable batteries on the market that are in the 2000mAh range that will retain 80% of their power if left standing dormant. I didn't think these would work and was always trying to get the most powerful batteries I could but these have proven my theory incorrect and in actual fact will out last the 2800mAh battery. I don't know where in the world you are but my first introduction to this type batter was with a Sony brand, now I have seen them in the department store check out line. It's pretty easy to find then as they state right on the package ready to use and claim the battery power holding capabilities right on the package. I don't think it's your camera I'm sure it's the batteries you are feeding it. Hope this was a help

Camera flash i generally use my camera on auto mode so i don't have to play around with buttons! however after loaning my camera to my sister for a week my flash is no longer as great as it was!! I used to take pics and the flash would light 2-3 times giving a great, bright picture. It now flashes once before the pic is snapped giving a dark picture.

Batteries "depleted" my camera was working perfect with some rechargeable NiMh batteries i had bought, giving me about 400 shots / charge. However at one point, for no apparent reason, when i used them, they would be shown as 'depleted' by the camera after about 4-5 shots, shutting the camera down. It stayed like this so I decided to buy a set of new NiMh batteries, i bought panasonic brand.

I have had an Pentax Optio S10 auto focus camera for about 3 years and it hasn't missed a beat. But now it will not take photos in flash mode. I have tried the usual settings as per the manual, and noticed a previous posting of the same issue. The response was to recharge the battery, which currently I am doing. The indicator on the camera's LCD however shows the battery to be almost fully charged though. Would this be the same issue? Any assistance would be greatly appreciated. Graham

Canon Squeal I recently bought a Canon A1 35mm film camera off eBay. The outside is in amazing condition but the seller did not use the camera for a very long time so it had not been lubricated.

I'm not experienced enough to trust lubricating it myself and wanted to know if you did this in your store and if you could give me an estimate on how much it would cost. I'm
