So design it like a CPU socket? Laptops usually don't have socketed CPUs because they also need to mount a heatsink, but RAM doesn't have that issue.

- InitialLastName 5y agoSo an FM2 socket (to pick one of the more reliable ones), which has ~900 pins has a 4.5in^2 area and adds ~.25" in thickness, while reducing the maximum speed you can get through the chip at the very low voltages necessary to run LPDDR, which is what I meant by compromising speed and power. Not to mention that socketting parts reduces your production yield over SMT, increases your assembly cost, and cuts reliability (it's fine on a desktop because you almost never move your desktop, and there's usually a big thermal assembly bolted on top).
- ant6n 5y agoPentium m used to be socketed, pretty reliable, and available for thin laptops. I'm not trying to dismiss the difficulty, just saying they could perhaps be overcome
- InitialLastName 5y agoHardware engineering is ever thus: Difficulties can always be overcome, but every cost adds 5x that cost to the MSRP.
