Thank you sooooo much for this video. I am no laptop technician but I have this same exact laptop that had the same issue and followed what you did and when I cleaned the ram stick and reassembled everything my laptop is working fine again. Was down from work for 3 days without my laptop. Thanks again. Blessings 🙌🏽
