AMAZING fix of DELL ALIENWARE 15 R3 laptop (sound issue, lights issue, EXTRA usb)

Guys I want to share with you my experience, problems and how I solved them with ALIENWARE 15 R3 laptop. Sound issue was a quite challenge but I solved it with scrap laptop speakers, nokia handsfree wh-203 audio card and PAM 8301 class D audio amplifier. And also How I solved issue with broken connection for left tron light, found wiring by colors for 12 hair-wires. And installed USB Hub. My instagram; My Pinterest: My Faceboo
