Laptop Question
Hello,
I'm working on a Lenovo T460 that has been having trouble charging as of late. Its worked well since I've owned it for a few years. When I went to use it the other day it was dead and wouldn't turn on (was sitting on an Anker 65W GaN charger).

Hi, I have a Dell Inspiron 7567 LA-D993P that I've just got running.
There was corrosion around PU1503 which shorted PC1518 & blew PL1504. (Reference pictures attached)
I've replaced PC1518 & PL1504 & the laptop is now running however I now have another issue.

Here are the tested scenarios:

1. With the laptop running on battery, I plug in the 150W charger & the charger shuts off (no LED, protection mode) but the laptop remains running on battery.

2. With the laptop off, plug in charger (LED says on) & the front charging...
