When computer is ON the battery level does not change.
When DC Jack cable is inserted or removed, it updates the battery health.
It charges the battery when battery is connected, but does not show charging or progressing in % percentage in the system. Unless removed and reinserted.
Tried a different battery same issue.
Ubuntu Live 20 and Windows 10 both show 33% Plugged in.
Windows 10 shows plugged in ONLY. Ubuntu says Charging but stuck on 33%
33% is at 12.45V and it’s increasing and charging the battery when tested with multi meter.
Battery rating is 13.2Vdc model BK03XL HP 3470mAh
I have not attempted to replace the BQ737 as I feel the readings are OK, but please advise. I've provided as much information as possible and let me know what other information you'd like.
Battery PIN connector on BOARD Readings:
1 Ground
2 Ground
3 Ground
4 36k
5 5.96M
6 5.98m
7 HARD to get reading, jumps from 8.6M to 1.15M 30K then up350K then keeps cycling like this.
8 SAME behavior as Pin 7.
Pin 7 & 8 go into MOSFET PU4408 DRAIN and Diode , 2 caps and R010 Resistors.
ENE Readings
ENE KB9028Q C diode Resistance
77 SDA0 0.56 2.48M
78 SCL0 0.56 2.48M
79 IEDI_SDA 0.43 11.53k
80 IEDI_SCL 0.43 11.53k
Charge controller is the BQ737
I have a bad identical board with different issues and the reading off that in diode more and this one are pretty much identical except where stated:
