Product review (5 stars): Saved $$$
I was a little scared to do this myself, but I watched a YouTube video on how to replace the part and got to it. I have a DV5451AEW/XAA 01, and though the part fits and works, the control board wasn't where the video said it would be! I found it and replaced it just fine. There were tabs to keep the cover in place on both sides of the original board, on this replacement part they were only on one side. Don't think it's a big deal because I saved about $300 by doing it myself.
