Built-in obsolescence ?

Since 1 year, I can't use my Canon powershot for more than 15 min before it tells me to change the batteries, and there's no apparent reason for that at all. If I change the batteries or use alcaline batteries, it doesn't help.

I watched a tv show about "built-in obsolescence". For example, they talked about a guy who discovered that his printer has an EPROM that store a counter and it is programmed to stop functioning after a given number of prints. He found a software that allows to reset the EPROM and his printer work again like a new.

I thought it may be the case of my camera: that there could be an EPROM that count the number photos taken for example, and the camera would stop working properly after a certain number.

Have you ever heard of anything like that about Canon cameras?

I'm wondering if CHDK allows to reset something in an EPROM and make my camera working like before.

Thank you

AFAIK,  that's never been mentioned here before and there is currently nothing in CHDK to do anything like that.

No, and there's a lot of people using old cameras here. That includes some who have done vastly more shots than the designers would have expected via timelapse scripts.

A far more likely explanation is that the contacts in the battery compartment are not conducting as they should, due to mechanical damage or corrosion.

You can use CHDK to display the actual voltage read by the camera. See http://chdk.wikia.com/wiki/CHDK_User_Manual#Battery (note the low/high values only affect the CHDK display, not camera limits)

There has been some experimentation with the camera limits too: http://chdk.setepontos.com/index.php?topic=4037.0

Which model camera do you have?
Don't forget what the H stands for.

Now that you mention it,  there have been quite a few posts about this.  Here's five of them :

http://chdk.setepontos.com/index.php?topic=3191.msg30715#msg30715

They all recommend cleaning the battery contacts and the camera contacts. I seem to recall another post about a good way to do that inside the camera but I can't find it right now.

Update :  found them

waterwingz is correct in his observation. As an ex servicing guy, the majority of problems I encountered were dirty contacts.

http://www.crcind.com/csp/web/functdisp.csp?lng=3&country=ALL&brand=SERVISOL#CLP

There are a number of products in the Servisole range which are useful.

Servisol Aerokleane 50 is in an aerosol can. While I have not used this particular product; similar products come with a 200mm extender tube which can be attached to the nozzle and be directed onto the internal camera contacts flushing away accumulated dirt.   

Edit:

http://www.electrolube.com/docs/lubricantmain.asp?id=65

One product I regularly used in the electrical and electronic servicing industry was Electrolube.

The product is listed as a cleaner. Check with the manufacturer's data sheet if it is suitable for cameras.

My camera model is Canon Powershot A530
I bought a new camera because of that problem (Canon G12) but it could be useful if I could still use my A530.
I'll search through your links later when I have time for that and I'll let you know if it helped me.

Well thank's for your answers and for taking the time to give me some links. That's great.  :)

Also useful when the contacts are particularly grubby is a fiberglass cleaning pen.

These are not very expensive, and can shift dirt that the solvents wont budge.

Try this search for something suitable.

http://www.ebay.co.uk/sch/i.html?_sacat=0&_from=R40&_nkw=fiberglass%20cleaning%20pen&_sop=15

Access to the internal contacts might require some disassembly, or careful probing. Take care to avoid getting the fiberglass residue in your fingers or the optical components of the camera. (This applies to the solvents too)

I live in Australia. The products I listed are readily available from the local electronics shop. For more specialised items RS Components are a good supplier.

Direct link to RS Components UK contact cleaners.

http://uk.rs-online.com/web/c/?sra=oss&searchTerm=contact+cleaner&x=27&y=13

The bigger issue that requires addressing is good housekeeping practices.

The plating on battery contacts, batteries and memory cards are designed for trouble free service for the life of the product.

Too many people purchase portable electronic equipment products and permit contaminants in their environment damage their equipment. Hence the battery contacts, batteries and memory cards become contaminated with foreign matter due to inadequate storage conditions. 

I keep all my spare batteries and memory cards in small sealed plastic containers packed in foam. I use a two shelf concertina metal tool box to store all my chargers, spare batteries and memory. The bottom of the toolbox carries an assortment of cables.

I also keep a cheap multimeter on the top shelf of the toolbox for field diagnostics.

When I use my camera, I also carry the toolbox in the boot of my car.

The bare essentials; two spare fully charged battery sets and two memory cards in individual sealed containers will fit neatly inside a small plastic lunch box container.

My primary camera, a Canon S3IS is still in pristine manufacturers condition, because it is packed in foam in a carry bag I purchased from a ladies handbag shop.
