It's built into the system...

The PDA toy, 17 years old now, who uses something this old?

in what country, DLS varies by country and state
and the rules changed here, in 2005. (wiki it)
it's winter here, in USA< so.. you are on other half of earth. (lower)
most computers made for 42 years, , ALL use a RTC chip
same chip as in a wrist watch( close to same, very close)

this chip does all that magic even to the level of a
perpetual calendar ! wiki that.?
so the BIOS can set (all real PCs) all that and the OS too.
when you change the OS time and date it then goes to the
BIOS RTC page and changes it there so they are in sync.
they Sync, up,

I do not know where Any OS stores time, after all it be different in all 100's of OS made, and your old relic PDA , gawd knows.
your manual for Jornada
tells you on PAGE 13, when you reset the Jornada, or or run it the first time, it asks for time city and time zone.
what makes you think this toy device even does daylight saving time, (it have to do every city on earth to do that , no easy thing)
on a real computer here, we can set our clock to WWV time.
via the WWV or WWVH, radio site, here, "atomic time"
then it sets you per the daylight savings (bit set selection)
That is how it works best on a real PC. or notebook.
maybe your Toy PDA is set this way (page 101)
Using ActiveSync, you can synchronize information in Microsoft Outlook
or Microsoft Exchange on your desktop PC with information in Pocket
Outlook on your hp Jornada."
but wait MS shut all that down long ago......

I googled for you and found very little on the RTC functions of you PDA. (but it is too old now, really)
the manual only has very little on topic, (so is limited in features)

my guess is you are looking for something that DOES NOT EXIST.
seem so, no? not in the official book
HP forum zero hits.
google zero hits.
last Jornada sold on ebay for $5 ,gets you 7 of them,
71cents (USD) each, less than 1 PEACH, here
they are not considered here, just trash.

All you have to do: Select Device Manager, select "Universal Serial Bus controlled". Re-install the USB driver from Active-Sync CD. That's it.

Weird! I would try an alternative Windows CE MP3 player such as Xaudio or PalmPlayer to see if they do the same thing. I have trouble believing it's hardware related because AFAIK the MP3 decoding is all done in software, but I guess it's possible.

Hi, You need "localization" software: it translates system commands as well as provides virtual keybord layout, handwriting recognition. I am using PenReader and Polish Localization done by Paragon Software ( avaliable on Handango) ; they have Spanish version as well. Thaer are other companies which do same sort of software.

Maybe he's using ClearType and you aren't?

why not ask at HP.com
the maker
why flash it at all?, if it works or did, why do that?
why risk a bad burn and bricking any PC.

The Jornada 568 has its OS in masked ROM. There is not an upgrade available.

I have a Jornada 568 but I've never seen the behaviour you describe. Is it possible that you damaged or caught a small part when you installed the new battery? Your new battery, was that the small round battery or a battery pack on the back of the unit. "Resetting to Factory defaults" suggests that there is no power at all, doesn't it? If the small round watch battery is dead then that might effect the clock.
