This is for jdw5155. Before you buy this box from HP, you need to check nvlddmkm.sys BSOD. Just look it up on google and you will see there is some sort of conflict between microsoft, nvidia, and HP, that has never been resolved and there is no solution. My laptop lasted 14 months and totally crashed. The battery lasted the same amount of time, and they cost $120. These people put out a trash product. You should consider other OEMs.
