Hello,

My steps:
1. modprobe -r bq27x00_battery
2. bq27200.sh
LOOPMODE=0
Reading values...........................done.

CSOC: 75 % RSOC: 75 %
Average Current: 191 mA
TTF: 65535 minutes TTE: 461 minutes
NAC: 1468 mAh CACD: 1468 mAh CACT: 1468 mAh
SI: 10 mA STTE: 8227 minutes
MLI: 979 mA MLTTE: 88 minutes
AR: 0 mA ARTTE: 65535 minutes
Last Measured Discharge: 1943 mAh
Cycle Count since Learning: 16 Total Cycle Count since last full reset: 16
Reported Battery Voltage: 3745 mV
Battery Gauge die Temperature: 28 C
Flags: 0x14
Charge:0 NOACT:0 IMIN:0 CI:1 CALIP:0 VDQ:1 EDV1:0 EDVF: 0
eeprom data:
ILMD=1958 EDVF=3000 EDV1=3248 ISLC=19
DMF=14700 nanoVolt SD=201 thousandths of percent per day
AGELMD=1 TAPER=97 mA
IMLC=979 mA
3. bq27200.sh 5
mv RSOC CSOC mA NAC CACD CACT TTF TTE TEMP EDV1 VDQ
03:03 3503 53 53 -35 1027 1027 1027 65535 1752 26 0 1
03:03 3192 53 53 -124 1026 1026 1026 65535 495 26 0 1
03:03 3351 53 53 -251 1026 1026 1026 65535 245 27 0 1
03:03 3261 53 53 -121 1026 1026 1026 65535 507 27 0 1
On those last values the n900 turns off. GSM was turned off and Brightness was on the low level. But EDV1 and VDQ was not changed.
I am found here:
https://wiki.maemo.org/Bme_replacement
Pali: Add two gconf values. First (bool) to enable shutdown device at EDV1 flag, second (int) to shutdown device at specified <= voltage. Default values: bool = true and int = 3150 (as suggested)
But not know which parameters must be changed with the gconf.
I use BME re and kp53.

Thanks.
