G5 5587, not charging
My Dell G5 5587 wont charge after my cable, that had exposed wires near the pin head, stopped working. I went and bought a new original 130watts charger and the charge light comes on and then disappears, with the message "AC power adapter wattage and type cannot be determined" displaying. The battery i have is a new one but has drained due to not being able to charge. The laptop survives only from the power of the charger but wont charge. I have seen tried other original chargers and even a few 180w chargers with no success. I am not sure if my previous charger short circuited something on the motherboard or if replacing the dc jack would do the trick. Looking for any other suggestions to rectify the problem.

There is likely a fault with at least one of three items:
It's a process of elimination to figure out where the problem lies, or at least where it doesn't lie. For example, if your AC adapter is recognized and works on another Dell laptop, then the problem is likely your charging jack or charging circuit.
Check if the light is lit at the plug end of the AC adapter or on the adapter block. And see if that light remains lit when you plug it into the laptop's jack. If the AC adapter's light goes dark when you plug it into the laptop, then the fault is likely with the jack or the circuit.
Try another genuine Dell AC adapter of at least the same wattage/amperage. If that second Dell AC adapter works, then the fault is likely with your AC adapter. If it doesn't work, then the fault is likely with the jack or the circuit. The jack is a relatively inexpensive item that is not difficult to replace for someone experienced in working on laptops.
If a good AC adapter and a new jack won't work, then the fault is likely with the charging circuit on the motherboard, which would normally require replacement of the motherboard.
Also, it's worth trying a reset:
There is a centre pin in the adapter's plug (the end that connects to your laptop's jack/port). If that centre pin is broken or bent, then that is the cause. If it's bent, you could try gently to straighten it. If it's not bent, clean out the connector with Q-tip and 99% alcohol, and do the same to the jack.
