The first laptop with LPCAMM2 memory is finally here. He iFixit people got the Lenovo ThinkPad P1 (Gen 7), which uses LPDDR5X memory in an LPCAMM2 module that you can upgrade or replace by simply unscrewing it from the laptop's motherboard.
This is a major change from the existing LPDDR memory in most modern laptops. This type of memory is usually soldered to the motherboard, making it very difficult to upgrade. LPCAMM2, or Low Power Compression Connected Memory Module, offers modularity without losing the power efficiency of LPDDR.

Traditional DDR RAM uses SODIMM drives that are inserted into the motherboard, just like in desktop PCs. As iFixit points out, LPDDR is much more power efficient, but must be soldered directly to the motherboard, as close to the processor as possible. Until now, manufacturers have had to choose between upgradeable RAM and low-power RAM. LPCAMM2 attempts to split the difference by attaching to the motherboard with screws, rather than soldering them. And unlike SODIMM devices, each LPCAMM2 module is dual-channel, so you only need one, not two.
As shown in the hands-on video posted by iFixit, you can replace the LPCAMM2 on the new Lenovo ThinkPad P1 by removing the back of the laptop and then removing the battery. From there, you can remove the LPCAMM2 by removing three Phillips head screws.
In addition to Micron, Samsung and ADATA are also joining LPCAMM2. Hopefully that will mean you'll be able to upgrade your memory if it comes with a measly 8GB of RAM, but we probably can't count on all manufacturers to make the switch.
