That 90W AC power adapter will not work. That AC adapter part number V3KCV was only sold with Vostro and Latitude laptops. 15 R3 validated AC power adapters.

Hi everyone I bought a used laptop Alienware 15 R3 from eBay. Specs = i5-6300HQ1060 The laptop came with 90W genuine Dell charger. Is this charger OK for this 15 R3? Because I see on Dell web or other websites 180W or 240W? Should I replace this charger? Thanks a lot for your/any answers. [IMAGE]    
15 R3, charger?
