"As a computer repair professional with 34 years experience, including 7 years as a Dell Field Repair Technician, without knowing the make or model of the device, we can only guess what the issue is caused by.
That being said, when a laptop can only function via the AC Adapter and the battery refuses to charge, either the motherboard is not sending the signal to the battery to be charged, or the battery is depleted and can no longer hold a charge, or the power transfer cable between the battery and the motherboard is not sending the charge between the two.
Without actually examining the unit, it’s impossible to know which. In my professional opinion, and without more details, the simplest fix is to replace all 3. The motherboard, the battery, and the transfer cable.
If your unit is still under warranty, then call the manufactures Helpdesk department, tell them the Service Tag/Serial Number of your unit and they will advise you after that.
If the unit is out of warranty, ask the manufacturer if you can purchase the parts I mentioned above and do the replacements yourself. If the costs to repair it exceed the cost of just buying a new laptop with a new warranty, then you have decide if this is worth it to you.
Good luck.
PS
In my personal experience, I don’t recommend buying third-party parts that are not manufacture compliant and approved. Just installing them will void the remainder of whatever warranty remains, if any. If the warranty is expired, then you can do as you please."
