Just use the pic numbering left to right each of the 4 rows.

Start at the top and remove in sequence, placing each on a strip of heavy tape to keep the screws in sequence.

Place a second strip on top when finished to secure the sequence until it’s time to re-assemble.

Very poor & sketchy guide! NO mention at all of how to handle the other wires involved in disconnecting the screen (lid) from the laptop base, eg: the wireless antenna connections and instructions like: “Unscrew the screws holding it down” are far too vague! holding WHAT down ffs!!!!
