I have an xps l401x i5 processor windows 10 64 bit . There are 3 touch buttons on the palm rest assembly as u know but the last end is poping out the end where waves max audio. And the left button of the touchpad is also not working pls give me a solution! I have removed the palm rest assembly and I do not see any damage on it . I slightly lifted the sticker on the top and I could see a small round coming from the part pls tell me what should I do. I dropped the laptop one time and the hard disk was replaced.
