  • I assumed display damage because every time I’ve seen these artifacts it’s been due to a damaged display matrix, but i agree that if it’s intermittent and isn’t some kind of unusual defect in the display, the ribbon coming partially loose sounds most likely, followed by cable damage (e.g., pinched by lid hinge).

    Ribbons are usually pretty secure, especially from factory if tape hasn’t been removed before, but with enough heat (e.g. left in car outside) and jostling, the tape can loosen, and cable’s weight plus jostling can be enough for ribbon to pull itself out.

    To quickly check without opening case i would try lifting the machine in two hands and driving it gently but firmly into your right palm (which would jostle the ribbon toward/into its terminal). If it’s loose, i would expect to see the display respond in some way after at most a few tries, if the ribbon cable is loose. If not, it’s still worth opening and re-seating ribbon to be sure, but jostling it a bit should immediately worsen or improve the visual artifacts, confirming the diagnosis.


  • No worries. In case this is your first display replacement, few quick tips…

    1. Helps to skim video teardowns like this
    2. Take photos of internals of electronics when you open them up so you can reference them later after reassembly.
    3. Keep track of screws. Trick: unscrew but leave them loose in the holes of the case tray with pieces of tape over each of them. Then you can remove tray without concern.
    4. Bare display edges are especially fragile and often have coatings that scratch easy. Trick: leave protective film on, just put a few pieces of folded tape on edges so you can pull off after install.
    5. Your display connects to the mainboard with two connectors wrapped in gaphers tape the right side: right side of laptop mainboard
    6. Display ribbon terminal (tall one far left) is more fragile than camera/lid sensors (wide one far right). Trick: use guitar pick or credit card to lift clamp right to left, never knife
    7. Ribbon itself often has physical tabs or printed white/color blocks indicating seat depth. This makes it far easier to verify its secure before closing case.

    Good luck!













  • Theoretically, I would say yes it’s possible, insofar as we could break down most subtasks of the development process into training parameters. But we are a long way from that currently.

    ETA: I suspect LLM’s best use-case in this hypothetical would not be in architecting or implementation, but rather limited to tasks with human interfaces (requirements gathering, project planning and logistics, test scaffolding, feedback collection/distribution, etc).

    If the unironic goal is to develop things without any engineering oversight (mistake) then there’s no point to using programming languages at all. The machine might as well just output assembly or bin code.

    What’s more likely in the short term are software LLMs generating partial solutions that human engineers then are asked to “finish” (fix) and maintain. The effort and hours required to do so will, at a guess, balloon terribly and will often be at best proportional to the resources saved by the use of the automatic spaghetti generator.

    I eagerly await these post mortems.
