Asus ROG GL502VM z MB: GL502VM rev 2.1 nie ładuje baterii

Witam

Laptop uruchamia się na zasilaczu oraz na baterii natomiast bateria nie jest ładowana.
Podmieniłem BQ24708s, przeprogramowałem BIOS oraz KBC.
Na gnieździe baterii po jej odpięciu jest 0.9V, z baterią jest 15V, na clk i dat jest 3.2v,( po podpięciu baterii na multimetrze widać że jest jakaś komunikacja).
Na innej baterii(zamienniku) jest taka sama sytuacja.

pomiary na BQ24780s:
1 - 19V - ACN
2 - 19V - ACP
3 - 18.5V - CMSRC
4 - 24V - ACDRV
5 - 3V - ACOK
6 - 2.6V - ACDET
7 - 0V - IADP
8 - 0V - IDCHG
9 - 0V , 125mV - PMON
10 - 0V - PROCHOT (
11 - 3.26V - SDA
12 - 3.26V - SCL
13 - 0.05v- CMPIN
14 - 0.05v- CMPOUT
15 - 0V - BATPRES
16 -0.05v TB_STAT
17 - 20 14.9v
21 - 1.1v ILIM
22 - gnd - GND
23 - 0V - LODRV
24 - 6.07V - REGN
25 - 14.9V - BTST
26 - 15V - HIDRV
27 -15V - PHASE
28 - 18.9V - VCC

Proszę o pomoc w dalszej diagnozie

Hello!

Install a Battery Mon software and post a screen of "Battery Info", when the battery + power supply are connected.

when battery is disconnected:



and when baterry is connected:



KBC to replace?

Have you checked the machine with a genuine Asus battery?

I bought 3rd battery and:



still not charging.

- Measure the resistance between pins 19, 20 of charger chip.
- Measure the resistance between pins 25, 27 of charger chip.
Don't forget to remove the main battery before taking the measurements.

- Measure the resistance between pins 19, 20 of charger chip. 20 ohn

- Measure the resistance between pins 25, 27 of charger chip.[/quote] 19 Mohm

Measure the voltages to ground on pins 5, 15, 18, 19, 20 of charger chip in the following cases:
a) Connected power supply only (without battery).
b) Power supply + battery connected.

I measured one again and:
- Measure the resistance between pins 19, 20 of charger chip. - 23kohm
- Measure the resistance between pins 25, 27 of charger chip - 10Mohm

a) Connected power supply only (without battery).
5-3v
15-0v
18-0.8v
19-0.8v
20-0.8v
b) Power supply + battery connected.

5-3v
15-0v
18-14.3v
19-13.4v
20-14.3v

Also measure the voltages to ground on pins 17, 24, 28 of charger chip in cases "a" and "b".

a) Connected power supply only (without battery).
17 - 0.9V
24 - 6v
28 - 19v
b) Power supply + battery connected.
17 - 14,3v
24 - 6v
28 - 19v

Is this battery a genuine Asus, or a replacement one?

I have 2 genuine and one replacement. 3rd baterry is genuine Asus

Does the charging LED lit, when the machine is turned off with power supply + battery connected?
Measure the power consumption (in mA) of the board, when the machine is turned off with power supply + battery connected.
