It could be that the battery is failing and that the charger can't do both i.e. charge the battery and power the laptop at the same time.
With the laptop turned on and working, create a battery report to check the condition of the battery.
When you have the report, compare the Full Charge Capacity value versus the Design Capacity value as shown in the report. For a good battery they should be nearly the same value.
You can work out the condition as a percentage by using the formula: Full Charge Capacity value x 100 ÷ Design Capacity value.
If the battery condition is <35% consider replacing the battery.
Here's the maintenance and service guide taken from this support webpage for the laptop.
Go to p.34 (42 of 122 pdf) in the manual to view the procedure to remove the battery and also the battery part numbers.
Search online for the part number only, to find suppliers that suit you best

If a laptop battery charges only when the PC is switched off, the issue is usually related to the power adapter, battery health, or charging circuitry. First, check if the charger provides enough wattage; a weak or faulty adapter may power the laptop but not charge the battery while it’s running. Inspect the charging port for dust or damage. Update the battery drivers and BIOS, as outdated firmware can affect charging behavior. Also check power management settings that may limit charging while in use. If the battery is old, it may struggle to charge under load. If none of these help, the battery or motherboard charging circuit may need replacement.
