15 DC15250, not working with old Latitude power adapters
Hello
My old 65W power adapter from my recently used Latitude will not charge my new Dell 15 DC15250.
Of course with an 7,5 to 4,5 mm adapter cable.
All specs look the same on the adapters.
Are there any workaround?
Best Regards from

Dell would never test Latitude AC power adapters on the 15 DC15250. You should only be using the provided and tested 65W AC power adapter that shipped with the 15 DC15250.

If the adapters are not OEM, chances are they won't complete the charge circuit needed to charge the battery. Dell does sell a plug adapter for older AC adapters.
