battery is good. I actually charged it in a m15 R4 I owned and it charged normally without issue, which is how I realised that the laptop would turn on with just battery power.PQB1- Source to Drain- 3.3[B]MΩ[/B]

Source to gate-

It's an 11.4v battery pack. It was at 62 percent earlier and now at 81% after charging for almost 3 hours.

finally to around to doing this. So the battery does charge. But very slowly, like 10-15 percent per hour. maybe that's why I thought it was fake charging previously. So I figure a charging voltage of 11.3v-11.75v is too low.

on the Dual Diode with the adapter plugged in:

Pin 1- 19.08v
pin2- 19.46v
pin3- 11.35v (mirrors voltage to the battery)...

Well it is "fixed" it was the ISL95522A itself. Bought on AliExpress lol. I had a known working ISL95522H that i tried into his laptop in the past and when i put it on all the voltages came back. Now it still appears to be fake charging. I am getting 11.75V out the output to the battery. Battery is at 10.94v at 88%. Where should I start looking?...

on PDB2 I have:

Pin 1= 19.12v
Pin 2= 19.48v
Pin 3= 175mv

and my bad, I bridged pins 17 and 18 on the ISL95522A. not 16 and 17. I have 5.1v on VDD_CHG on pin 18 and 19V on pin 17 DCIN_CHG...

I bought this laptop sometime ago with an issue of it not detecting the battery but would work only with the charger, eventually, I found the problem was a missing resistor and replaced it and fixed the trace to it, it would detect the battery, but it would still not charge, it would detect the charger but fake charge. I recently moved so I did not have my regular microscope, I used a digital microscope I had to reflow/retouch the contacts of PUB1 which is an ISL95522A. I did not realise that I had bridged pins 16 and 17 and when connected to the charger, it blew the IC and the 10a (PRB13) resistor...

did you get this fixed?
