Am testing Pali's bme replacement. Does the job, led's flashing etc. The only thing is that the led never goes green and the status area icon keeps pulsing. Battery has good charge by then, and is perhaps full by any standard.

Have read k-p threads where bme replacement is mentioned. Rather than posting reams of perhaps wrong output here (e.g. hal-device bme), I would be gratfeul if Pali could specify what he might need. Or is no green led normal?

Thanks.

Methinks BME-replacement does need its own thread.

How sad, I must correct myself. I got a green led during the last charge. Thing is, this time I forgot the phone and hours later there it was green.

It appears that "bme replacement" has a different charging "profile" to "bme stock" and takes longer to produce the green. I use "bnf" and am content frankly at anything 95% or so. Less of course is better for the battery.

Detecting wrong charger type. That may explain the differing charging profiles.

How to revert back to stock bme?

I have a similar problem, but my cell phone had some circuit in the device. The cell I bouht was used and was defected. Previously, I had problems with restarts after shutdown, then with running it properly.
I installed these four packages and after a reboot my cell indicates the charging procces by the status area and by pulsing of the yellow LED.
After charging the battery and disconnecting the charger it still shows me loading and the LED stays constantly green.
When the cell is switched off, the device receives 0.35A (350mA) from battery.

What's the problem?
Can this be checked diagnostically?

I am encountering a bug that causes the status-area-applet show constantly 50% charge. If I charge the battery full overnight and still keep the charger connected I get full battery, but the second I disconnect the charger the bar drops to 50%.

Otherwise the bme seems to work normally.

You can downgroad it to stock bme version:

Code:

apt-get install bme-rx-51=0.8.55+0m5
