Are you using bme replacement or not? From your output I see that your battery is totally empty (CSOC: 0 % RSOC: 0 % NAC: 0 mAh CACD: 0 mAh CACT: 0 mAh). And in this state if capacity is 0mAh status menu plugin will show that message about uncalibrated battery. Also please provide output of command: hal-device bme

I'm not sure what bme I'm using, I don't remember changing intentionally anything battery related packages when the statusarea applet appeared and when it changed to displaying the not calibrated text. I just upgraded all the packages that were marked as upgradeable.

Here's the output:

Ps. the bq27200.sh I'm using is from here, I think there are several versions out there

Edit: I have USB-hostmode installed, back from the time when I had usb-port, so I might have the bme-replacement, if it comes with the hostmode packages.

Data for applet are there... I will try to find out why are not used.
@Kossuth: Can you give me output of this?
$ apt-cache policy status-area-applet-battery

I pushed to cssu-devel new version of system-services (part of upstart) nad ke-recv packages. New version has fixed generating /etc/fstab when maemo is installed on eMMC or SD card and has support for *static* /etc/fstab. And there is also support to run fsck on all partitions before mouning (/home and all other eMMC/SD card).

WARNING: Before installing new version of system-services package make sure you 1) do not have installed package kernel-power-settings or 2) have upgraded kernel-power-settings to version 0.17 (it is in extras-devel). Otherwise device can be unbootable!

Edit: I tried switching the usb-mode from peripheral to host with boost and after announcing stopping bme, the batterymeter went to 0% and I got it back only after returning to peripheral mode. Is this normal?

I install it on CSSU-stable and I have "Not data or Battery is not calibrated".

Version 1.0-4 has worked reasonably well.

hi. im not getting "Not data or battery is not calibirated" error. but my battery percentge is at 100 percent since last night. screenshot attached.

edit. im using CSSU-Thumb

@panjgoori: Do you have bme replacement or normal bme?

usbmode needs to turn off bme, but loading kernel drivers which provide battery information. after some seconds (30-60) battery applet should use these data and show them in applet.

@pinochio and @panjgoori: please provide output too:
$ hal-device bme
