Olympus C750 resetting

Ken,

I have spare batteries and even when I change them straight away - less than
a minute - the settings still reset.

I have the Olympus c725 and it is terrible for resetting, even a
little knock can do it when the cam is switched on, but one thing I
did notice was that if the cam is in a usable mode when changing
batteries it will reset. I have to make sure it is switched off
completely, lens retracted etc, then do the battery switch.

I have some devices that also too easily lose their internal
settings if more than a few seconds are taken to change the
batteries. A small capacitor is often used to maintain some voltage
when the batteries are removed, and if they deteriorate with age,
the protection time will be less than when the device was new.
Also, the higher the battery voltage at the time they are removed,
that greater the amount of time you'll have to replace the
batteries. This reduces the problem when alkaline batteries are
used, since unlike rechargeable batteries, when the device powers
off, the battery voltage will rebound within seconds to a higher,
safer value, giving you more time to change the batteries.

When I've had to use rechargeable batteries (and I suspect that
you *really* wouldn't want to use alkalines in your C750) I try to
minimize the time that the batteries won't be powering the device.
If your camera uses 4 AA cells, try to quickly replace only one cell
and then wait a few seconds before trying to replace the next one.
That one fresh cell will raise the total voltage in the camera
slightly, giving you a little more time to replace the next cell.
Repeat the process until all cells have been replaced.

If the camera has a socket that allows it to be operated using a
transformer or an external battery pack, having another power source
plugged in would probably give you an unlimited amount of time to
replace the batteries. Several old Palm PDAs (that used AAA
batteries) also had the same problem when changing batteries. They
could be fixed by opening the case and replacing the worn or
defective capacitor with a new one, preferably one having a greater
capacitance than the original. This is much harder to do with
cameras, as opening them is far more likely to cause some kind of
damage than opening a PDA. But if you can find someone that repairs
cameras, and who you can trust, having them replace the capacitor
might be a relatively inexpensive fix.

Thanks for the comments.

I got a reply from Olympus and they claim the camera has an internal battery
that may need replacing - by a technician of course. I contacted the
nominated repairer and he wasn't aware of an internal battery but quoted a
price of $AU145 if he could get a battery - not exactly an inexpensive fix.

It seems the camera does have a DC input socket so maybe I should try a
battery pack for that while I change batteries.

worth a try Graham, you could almost buy a new cam for the cash they
want to change the battery!

Hi...

For what little it may be worth, I've had several of the c-7xx
cameras apart for service - though NOT a 725 - and I've never seen
any sort of battery, nor had reason to suspect there is one.

IF there is, then the only way is if it's embedded in a chip.

Take care.

Ken

The rep for the 725 doing this reset is very bad. Of course I only
found this out AFTER I bought it.

The way I understand it this camera has a capacitor that supplies the
settings. It seems that this capacitor has failed.
