My PDA keeps reseting itself say after some days of not being used. There are 2 batteries. 1 main and 1 internal (for backup e.g. when you change main battery or power is low on main). Is this due to the internal battery not surviving? Any ideas as to why this is?

Which operating system is it running? If it's Windows Mobile 2003 SE or anything earlier then you will lose all your data when the power fails. This is because the storage system uses volatile memory which only maintains data when it's powered, once the power is gone so is the data. The internal battery is unable to sustain this memory for any period of time, it's only there for battery swaps.

With Windows Mobile 5 Microsoft changed to a more conventional system with the primary storage using ROM (non-volatile memory) and the volatile memory being used as RAM, same as in a standard Windows PC.

You may be wondering why they ever used volatile memory for storage but the simple reason is speed, it's faster than non-volatile memory and the PDAs have needed that speed.

It is Windows Mobile 2003. So it looks like there is no other way around this unless I upgrade the OS? (It's an iPaq h6340 by the way) so it's a multifunctional PDA but it doesn't really have a great deal of CPU power or RAM...

It sounds as though the main battery is not holding its charge for long, so you could either keep it plugged in to the mains when you're not usin it or get a new main battery (look on EBay, they're cheap if you're prepared to order from Japan - I bought 2 replacements from Japan, so I always have at least one battery fully charged, but that's because my PDA is used a lot)

Unfortunately I'm not that familiar with HP models as it was Dell PDAs I used at the time - I don't know how it is for your model but for many upgrading to WM5 didn't work that well.

groupie's recommendation for batteries is a good one, the only other real option is to try and use memory cards instead for all your installations and use a backup program for the main system configuration - if you store this on a memory card as well it would allow you to restore the system relatively easily.

I do know where you're coming from as I found this an incredibly annoying aspect of WM2003 and before - when WM5 came along and got rid of the problem I was more than happy to take the reduced speed. I found I would forget to charge the PDA for a couple of days, then it would wipe itself which meant it wasn't actually usable when I needed to etc. etc. meaning it really didn't get used that much in the end.

Thanks for the suggestions. Quite right John, it is incredibly annoying and I almost gave up and considered selling the PDA as a result.
