Hi @stormjaramillo
If you have a DMM (digital multimeter) first check that there is 19.5V DC on the output plug of the charger or try connecting a different, known working, compatible charger to see if it works. You can also try connecting an appropriate USB-C laptop charger, to the laptop's USB-C port on the rear of the laptop (next to the DC-In jack) and check if the battery starts to charge or not.
If the USB-C charger works OK and the normal charger output tests OK or if a known working replacement also doesn't work then this indicates that there may be a problem with the DC-In jack
Here's the maintenance and service guide taken from this support webpage for the laptop that may help to find out whether it is faulty or not
Go to p.49 to view the procedure to remove/replace the systemboard.
Once it is removed you can check if the DC-In jack, which is soldered to the motherboard tests OK from its input side to its output side on the board. If it doesn't then the jack is faulty and needs to be replaced as it cannot be repaired.
If using the USB-C charger doesn't work and the DC-In jack tests OK then further testing of the motherboard using the schematics for the board would be required to find out what's wrong.
