PDA battery always going flat

I have had an HP4700 for a couple of years.

It works OK but half the time I pull it out of the bag, the battery is flat.

Reasons include

1. Accidental button press wakes it up (this can be disabled in the Settings)

2. Accidental movement of any device in the CF slot wakes it up (cannot be disabled in any documented setting)

3. Accidental movement of the SD card wakes it up (likewise)

4. Accidental movement of the battery securing plastic pieces, causing the battery to come a bit loose, wakes it up and then kills all the data in RAM

The above are fairly typical of pocket/pc devices as a whole - every PDA I have had does the same.

When the battery goes flat, you lose all apps and config except the bare operating system, and have to go through the stupid initial config where you have to calibrate the screen and then copy/paste the stupid text from one page to the next.

First Q is whether there is any registry setting which can take care of 2 and 3.

Next Q is whether WM2005, with its flash-based memory model, helps in any way with existing apps. I am still on WM2003. The reason PDAs have these data loss problems is that all apps and config is held in battery backed CMOS RAM, not in flash.
