This is an HP laptop. I purchased it about 5 years ago, but I am selling it because I bought a new computer. I used it about once a week at most, and sometimes only once a month. I have initialized it for this sale. The battery has deteriorated with use, so please consider using it with the power adapter connected. Overall, there is no noticeable dirt, but as shown in the third photo, there is a black stain on the surface.
