As a first timer to this particular task, but with many years experience with PC hardware, the only suggestion I would make is changing the completion time from 15 minutes to 45-60 minutes.
That’s a tad more realistic for someone so unfamiliar with this particular type of job/notebook model that they had to look it up here to see how to do it.
15 minutes sounds like someone who has actually done it dozens of times before, and, hence, would not be seeking help here. A first timer would be wise to take more time and caution, certainly more than 15 minutes. Other than that, this is a great guide to replacing the zd8000 screen.
