Recently a user reported that their laptop screen was damaged in their carry case, likely due to the AC adapter pressing too hard against it. I ordered a replacement panel and five days later it was time to get to work.

It's very handy to review the computer manufacturer's documentation before beginning this kind of work. Fortunately Dell makes it very easy with a pictorial guide on removing the key components.

Start by making sure the system is completely powered off and the battery removed.
