Backup battery on Universal

[DareDevil]

Can anyone tell me why I can't see a display for a backup battery on my MDA Pro, previously on the Alpine I had a main battery display and a backup batt display??????????

[ady]

because there is none.

i gathered that much but is there a reason, does it mean if i let my current battery run dry i will lose data because theirs no backup???

[ady]

no you won't loose anything becaue the data is saved on presistent storage in all WM5 devices unlike in the case of WM2003SE where it was saved on RAM

because there is none.
There is a second battery soldered in the Universal,
but it is probably only for the RTC.

In WM2003 and earlier devices, as in PalmOS, the "Storage" for users is actually a part of the device RAM, which means that if it loses power you lose the contents, where the other part of the ram was used as execution memory (ie, like the ram in your desktop pc). In WM5 (and presumably later) this is the other way around, all Storage is in the device's (flash) ROM, and the RAM is *only* used as execution memory. This is why WM5 devices like Uni tend to have 128 megs of rom and 64 megs of ram whereas earlier devices tended to 64 megs of rom and 128 of ram. So basically you're not losing any more data by running out of juice than you would if the power failed on your desktop PC: If a particular piece of software is careless you might lose what's currently opened and unsaved, but everything else is persistent.
