Problem with charge battery on mobilePro 900c

Hallo,
I have problem with battery on my MobilePro900c. Battery is full (it is cca. 8.2V on my meter), I work with MPro about 3 hours, but MPro show without battery. Window battery propetries show 0% power and Main Batterries don´t show nothing.

Battery works for 3 hours...that is good.

Thanks, it is good, but why is indicator on my mobile is bad. And mobilePro show battery is low?

Check battery show again, use power icon in control panel, make sure a/c adapter is not plugged in when checking...

Have you tried a hard reset,( main battery & back-up battery removed)
back-up your files before doing this
Airhook

Whena I use control panel is there this information :



Main battery isn´t bold GOOD, LOW not even VERY LOW ( for example : Backup batteries is bold GOOD) on the pictures.

When I plug A/C adapter, notice MAIN Battreri is change on CHANGING and when is batteries is charge is there EXTERNAL.

I try hard reset, but is it still same.
HW is MobilePro 900 but SW is CE NET 4.2. Maybe, it is problem?

Configuration my MobilePro is:



In window Batteries (WR-Tools) is bad voltage 1.413 V, no consumption, no temperature

Sounds like you have a bad battery. Hard to say without trying another. Just use it until it doesn't work, and then worry about it...

It isn´t bad battery (I can work on battery about 2-3 hours).
I try plug in power supply (7.66V) instead of battery (without A/C adapter, sure).
MobilePro show me same information as before.
I think, it is some library (*.dll) or HW problem,... ?

I had a similar problem and found the internal battery switch (controlled by the external battery switch) had blocked in the open position (even when the external switch was in the locked position) but I had cmonex 2 installed and think this shouldn't be possible to happen to you, as with the standard ce.net rom the device wouldn't even start up without the switch in the locked position..

Hardware problems aside, I think there is a system hack to make the warning disappear

Speaking of cmonex' ROM, it probably couldn't hurt for vasekv to try reflashing the 900C with version 2. (I see it already has the right bootloader version.)

I solved problem with battery.
Problem was with internal battery switch. This switch was all time blocked.

Thanks for yours tips.

So, did the device start up even with the switch in the open position?

Switch was in postion push as lock is OPEN, but I think it had bad contact.
I cleared switch with oil and function is OK. Now when I unlock switch my MPro is switch off.

hey vasekv. I'm not sure I fully understood... is this the internal switch, did you have to disassemble the device to get to it? I assume so..
