Jornada 680 battery question

Worst case scenario, let's say you don't use the Jornada for a month or two without having it on AC power and the battery totally runs out, what happens then?

C:amie & Cmonex, I believe the HP diagnostics are written in the ROM/firmware by the firmware engineers, who have the exact port/register values to peek/poke (or inport/outport) with. WinCE 2.11/3.0 etc provides the system layer to abstract the h/w so that developers do not need to know every other hardware ya

unfortunately, it means also that apps are limited to the resolution this abstraction layer gives ...

hard reset.

heh, so, i hope you'll check out that mailing list

aw, Mike, no worries, I'm not in a rush to test it out, since I am not the one who needed to see a flashing icon on the screen! ... hehe

Hey Snappy, just tried this out but could not get it to work right, here are my steps, I downloaded your exe file into the Jornada in Program Files, I see the Green "batt" icon and double-click on it, the Green Battery icon appears in the Tray and also a prompt comes up with the Battery Status, I click ok in that small box and it disappears but so does the icon in the system tray too, questions:

1] How do I keep the icon in the system tray?

2] What is the "minimum" level I should let the Battery go down to before recharging and how can I set the red flashing icon for that specific level?

Thanks.

You really need to go through our support section.

Hey, thanks for the link, nice tutorial, ok so that answers 1 question that the lowest the battery should go down to is 20%, so I would like to set Snappy's warning at 25%, is this ok? I've seen others say that I should not go below 1/3 power level but I guess I will have to depend on the Tutorial for this unless someone gives me a reason to choose another % other than 20?

hey imo it's ok if you go down to 16% and then charge it right away. though i don't know about the 680. the 720 just gives this rudimentary info about the batt state: 100%, 83%, 66%, 50%, 33%, 16% and 0%. that simple... is the 680 different in this respect (giving more accurate information)?

Actually, the 680 is worse in this respect as it does not give you a %, it has 6 "Blocks" colored Black so Iam guessing that I have to divide 100 by 6 so each block should represent 16% or so? I am glad you brought this up because I had completely overlooked this issue, now I can't set at 25 so my choice will be either 1 block [16%] or 2 blocks [32%], thanks.

oh but the screenshot of snappy's batt utility shows 35% and that means it's more accurate. or was it just the emulator or what? can't remember... please check it.

Hi mike,

I just made a new build (SH3). It will trigger when the batt percentage hit 25% or lower. Once it recharges beyond 25% (ie more than 25%), the flashing will go off.

The app needs to be running for the icon to show. I've made the dialog box into a "toolwindow" so that it does not appear in the taskbar.

The emulator screenshot is not valid. Its just some numbers thrown back by the emulator through the sys API. It sometimes jumps to 125%!

On an actual device, it "*should*" display the right value, subject to the resolution of the value given by the sys API. Short of getting actual port/addr values for specific HPC h/w, this should be the best this little app can do for now.

Once again, all hail Snappy!

How do you remember all these API's? Do they just appear in your mind, or have you to trawl through the API library?
