Hi, I have a problem with a Lenovo IdeaPad Gaming 3 15ACH6 laptop. My nephew asked me to replace the charging port because the laptop wasn't charging. This issue had happened in the past, so I knew that replacing the port was only a matter of time. Until now, my nephew managed to deal with the problem using a temporary solution: bending the positive metal tabs inside the port with a thin tool. However, this had stopped helping for a while. Today, I replaced the port – and to my surprise, after the replacement, nothing happens when I plug in the charger: the power LED doesn't light up, the laptop won't turn on, and the battery doesn't charge.
I'm not sure if I could have damaged something during the replacement — I'm an amateur and do this as a hobby, so I can't rule that out. However, I followed all safety standards, and I've successfully done this before on other laptops. So I tend to think my nephew overdid it with bending the contacts and caused a short that damaged something on the motherboard, even before I replaced the port.
What's strange is that the charger protection doesn't kick in now — when I connect it to the laptop, it constantly outputs voltage, and there is voltage on the correct pins in the charging port. There is no short circuit at the charging port itself. I've noticed that when the charger is plugged in, some small components – and due to my limited electronics knowledge I’m not sure what they are... capacitors? resistors? – get very hot (I’m attaching a photo pointing out these components).
Schematics for my motherboard are here: https://www.badcaps.net/forum/troubl...64#post1725864
I’d really appreciate your help as you would for a complete beginner – in the past, you helped me diagnose an Acer laptop on this forum, despite my lack of expertise. What should I check and how at the very beginning?
