Hi @filbert ,

Thanks for the quick reply. I have already tried 3 original Dell Chargers and the issue is still there. I will replace the charging jack and hopefully, that will fix the issue. 

The charger is recognized in BIOS.

Thanks.

There is likely a fault with at least one of three items:

• the charger
• the charging jack
• the charging circuit on the motherboard

Try another genuine Dell charger of at least the same wattage/amperage. If that works, then the fault is likely with your charger.

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 charger 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.

Run Dell Diagnostics:
Immediately after pressing the power button to turn on the laptop (or after clicking the Reboot command), press and hold F12 to enter the One Time Boot Menu, select Diagnostics and press Enter. The Dell Diagnostics will test major hardware components.

Hold F2 while booting, to enter BIOS. See if the charger is recognized.

Hi, I replaced the charging jack, but the issue has not been resolved.

Are there any schematics for the mainboard or the charging circuit ? I want to try and fix it.

Thanks

While you can likely purchase a schematic for the system, it's really not an undertaking worth the time or cost -- even if you can find the faulty part or parts, unless you live in Southeast China, sourcing what's needed is just about impossible, and that's if you have a hot air rework station needed to even begin the repair.

Replacement boards run from well under $100 to about $150 -- you might also want to check the cost of used systems, which likely won't be much if any more expensive than that.
