Identifying correct replacement part on Dell 7520 17R
I have an out-of-warranty Dell 7520 that needs a replacement part. The part number on the 17R is CN-OWX67P-GSAD3. However, I can find no such part available anywhere. What I get is a replacement part for the 15R which is CN-OWX67P-GT074. I want to confirm that these two part are identical in their functionality. The part that needs replacing is part of the power supply for the laptop and I don't want to fry my motherboard with the wrong part.
