OK, then you did actually 'hard reset'. Like I said, the backup battery is
only there to allow battery swapping. It is meant for a minute or so, though
some manuals, screens mention a time frame a bit longrer than that.
Typically swapping a battery only takes 15 secs or so. A bad backup battery
is evidenced by your trying to swap a batterry and getting a hard restet
during that short 15-30 sec period. Unfortunately these things are internal,
and often soldered in. Some are just a charged capacitor.

The feature of shutting down when power is low, is an attempt to reserve
some percentage of the regular battery to maintain data at the lowest
possible current draw possible, radios off, screen off, essentially no
processing, just enough to maintain RAM. With a new battery that lasts 6
hours, the reserve when the saver feature kicks in may last 6 hours or 12,
depending on the device. With an old battery, it may shorten the length of
time you have to get real power applied dramatically.

All I can say is, do remember to take your extras, (your Battery Extender
would have saved you) maybe investigate and invest in a backup program that
features a low battery trigger, or, get a WM5/6 device to replace what you
have. These all have persistant memory. You can leave the battery out, lay
it on the shelf for a month, replace the battery and be right where you left
off. I wouldn't recommend this with applications open, mind you, but closed
files will remain. Oh, and you will have to suffer through all the reminders
you missed during the month. ;)

No. As I said, "...as soon as I placed the 2210 in its cradle, the
normal Today screen was displayed." Everything was normal.

But the same happened again yesterday, only this time it *did* get a
hard reset.

This is what happened. Lesson-learned, this time I was carrying two
spare lithium batteries, both recently charged. But after inserting
the first, the PPC still failed to start. I'll have to check the
battery; it was the oldest one I have, so maybe it's not holding a
charge. On inserting the second, the PPC started OK - but this time
did a hard reset!

I take automatic backups every morning at 07:00 so I restored the
latest of those, which at least got me back into Mem-Map and let me
record the remaining 10% of my walk. But of course
- I no longer had my pre-loaded track on the PPC (because I'd made
that shortly before the walk, well after 07:00)
- I lost all the earlier recorded track
- I lost all 3 or 4 overlay backups I'd taken at stages throughout
that 90%, as extra insurance.

I'll include the Battery Extender too next time ;-)
