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. Since two AC adapters don't work on your laptop, probably the adapter is not the problem. 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 it doesn't stay lit, 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. Run Dell Diagnostics:Press and hold F12 while booting to enter the One Time Boot Menu, select Diagnostics and press Enter. The Dell Diagnostics will test major hardware components. Also, it's worth trying a reset:
Hello, 6 months ago we replaced the battery with a brand new one and everything was ok since until last week, we started receiving this error : "Alert ! The AC Power Adapter Wattage and type cannot be determined." So we ordered a new PowerSupply directly from Dell but the problem remains. This morning, I plugged in the new power supply, and when I ran the diagnostic from the Bios, they said "Charger - The AC power Adapter wattage and type cannot be determined. The Battery may not charge."   What else can cause this problem? Thanks for your help !!
