Lenovo IdeaPad Gaming 3 15IMH05 GY530/GY531/GY532 NM-C871 Rev 2.0
Hello everyone, I come here in search of wisdom and hope.
I got this laptop with charging problems, apparently it charged ok while turned off but it would not charge while powered on, anyways I was doing initial measurements looking at the voltaje on the ID Pin, it is a 135W DC Adapter and the pin actually measured 1.9V that looks ok, anyways, while doing that, I accidentally shorted the ID pin DETECT(ID) with one of the 20V pins, sparkles and it automatically killed the TVS Diode PD102, and also made a cute burning hole on the middle of the KBC or EC chip UE1, it is a IT8227E-128...

Re: Bios gs557-gs558 NM-681
Actually I am not sure one of the dump is the EC, may be the EC BIOS? It's about 1MB, the other one is about 16MB and most certainly the actual BIOS, I have not been able to find another dump to test it and see if that fixes the issue

The laptop works fine with another adapter no problem...

Laptop AC adapter voltage drops
Hello everyone! first I tried search and find nothing, maybe I didnt search well enough? anyways...
I have this AC adapter, it is an HP 19.5V 3.5A central pin plug, when connected it powers on and delivers the voltage correctly and stable, when I Plug it into the laptop and power it ON it immediately drops to 6v-9v up and down, when I unplug it it takes like 3 seconds and go back up to 19.5v stable
So far I desoldered the main Cap as well as te 2 otput ones, tested and measured them, capacitance is ok and the ESR values seems OK, the big 120uf 400v ESR was .15, I replaced...
