Really sorry for not saying this before, do you think the PUZ1 is HS, I have trouble understanding if the PUZ1 has a link with the computer load -
Hello mon2, I received and replaced the PQB2/5/6 and the PUB1, which were new when I tested them. The battery is new, and it still won't charge.
Rereading our discussion, I realized I forgot to mention that I've been having this problem since the PCH11 and PCH14 exploded. I'll post a photo, and after replacing them with more robust models, here I am.Leave a comment:

I might consider ordering from AliExpress.
Thank you very much for your help.Leave a comment:

Okay, thank you very much. I'll get back to you as soon as I've replaced both MOSFETs.
For PQB2, should I replace it or leave it as is?
For your information (see photo), do you agree with me, B12 N03?...Leave a comment:

For information on pin 21 of PUB1, I have 1.047v up to resistor PRB21 on one side (pin 1) there is 1.047v and on the other side (pin 2) there is 3v3Leave a comment:

at pin 21 of PUB1 I have 1.047v with battery and charger connected, there is 0v when only the battery is connected or only the charger connected (battery disconnected)
Battery pin connected to the motherboard

Sorry, I misunderstood, at pin 21 of PUB1 I have 1.047v with battery and charger connected...Leave a comment:

On the motherboard connector, I have 19.92V.
I've already tried with three batteries.Leave a comment:

Everything works. The computer detects the battery, turns on the orange light, and Windows detects it. It tells me that the battery is 24% charged. The battery voltage is 14.8 V. Everything works except charging.Leave a comment:

On the 19V PQB11 ACEDT 2.5V adapter
I ran some tests.
For the PQB2, I have 19V on pin 5
and battery voltage on pins 3, 2, and 1.
With the battery connected and the mains plugged in, I don't have 19V on pins 3, 2, and 1. This is not normal....Leave a comment:

Hello, Mon2, could you please help me with the same PC (diagrams). My Acer PC runs on both AC power and battery power. Windows detects the battery correctly, and I have a light that indicates the battery is charging, but it's no longer charging. Do you have any idea where I could look for the problem?
Knowing that I replaced the PCH11 and PCH14.
Thanks in advance....Leave a comment:
