RE: dell inspiron 15-3552 not charging, getting mixed responses
I am running into the exact same issue. At first it would say incompatible adapter, although it was the one received with the system and worked fine for the most part.
Now it hardly works at all, and seems like I have to play with the plug for a long time to get adapter connection. This leads me to believe it is the charging port itself and unfortunately the full warranty just expired and is not in place for parts coverage only.
Rather disappointing that you get a year and then have to toss to buy a new one because of poor workmanship or parts. But if system cannot be charged and no battery or recharging docking station is available, then it simply because a worthless POS brick.
Perhaps last DELL I will by if this is the quality and commitment standing behind their products.
