Some of the laptop issues are a chain of dependencies that en up with mechanical and power envelope. That doesn't mean it's impossible, but say you want to go from 720p to 2k, that also requires more power, a bit for the panel and a bit for the backlight. The mainboard might not have a TCON and eDP or LVDS transceiver to drive such a panel, and the GPU might not be able to handle it either. So now that new panel needs three more things:
- Power supply
- Display transmission
- GPU
And those things in turn need more (or well, 'different') space, which in turn might not fit in the existing chassis. And if it does, you might still have the thermal envelope issue where the chassis can't support the right airflow in the right places, or the cooling solution might not.
None of those are impossible to solve, but they also aren't as simple as "just give me a different panel", because it's not really just about the single component, it almost never is.
We have had a lot of luck in the past with a single 'family' of computers (usually largely designed by compal, Foxconn etc.) having interchangeable parts, and the base models essentially being downgraded versions of the top-tier model, which means that as long as you stay within that family, you get to upgrade parts along the way.
Framework does an excellent job of keeping everything that still fits within the same envelope going. But if at any point the current eDP interface needs to be replaced to support higher bandwidth, that means that the possible combinations between panels, cables and mainboards is now a whole lot more complicated. Some panels might only work with some mainboards, which might mean you have to replace both at the same time, greatly reducing the usefulness of what remains. Currently we don't have a huge gap between previous generations and current generations, but I'm very curious what's going to happen when we do make another significant jump. Only time will tell.
- 6510 3y agoI imagine by that time you've used their market place often enough. Their used parts shop might be more awesome than the laptops. I can only imagine what it will look like in a few decades. Should be awesome. In contrast, I'm the 4th owner of a "free" asus laptop that broke shortly after it was purchased (by the first owner) They never bothered to return it. I have a pretty good idea what is wrong with it but there is about 4 cm of space when I open it. I need some long strong pliers to pull some distant plugs. In a repair video from someone who really knows what they are doing, he reaches deep inside, pulls the plug with great force then smashes the pliers against the pcb making the laptop jump on his desk. "this is normal" he said and proceeded to pull the rest the same way. I've been gathering the courage to do it for about a year now.
- AnthonyMouse 3y ago> And those things in turn need more (or well, 'different') space But this is the source of the problem. The lack of modularity and standardization. The first generation mobile Core i7 from 2008 had a TDP up to 55W. The base TDP of the current generation is the same, Ryzen is even less. It shouldn't need a different cooling solution to dissipate the same amount of power. The same is true of mobile GPUs. Don't layout the new board in a different configuration. Don't change the chassis. Just put the newer chips in it, in the same places they were before. Which means the newer boards and chips will be compatible with the older chassis. > say you want to go from 720p to 2k, that also requires more power If the new screen uses 20W instead of 15W, that shouldn't really matter. Screens typically aren't actively cooled and are also hinged into their own section of the chassis, so if the newer screen needs different passive cooling, it can come with that and still slot into the same base chassis. And if the new screen uses 20W instead of 15W, you should still have enough power unless the entire rest of the laptop is at max spec. If you have a battery and power supply that could support a 55W CPU and a 55W GPU, but you actually have a 25W CPU and a 30W GPU, the screen using an extra 5W should be irrelevant. > The mainboard might not have a TCON and eDP or LVDS transceiver to drive such a panel On the other hand, it might, because 2k displays have been around for more than a decade. And if it doesn't, you should be able to upgrade the GPU to one that does, and plug the display directly into the new GPU, which in turn plugs into a standard slot using PCIe that doesn't require anything else to be changed.
