Soldered RAM means no upgrade.

No, if the RAM is soldered to the motherboard, you can’t add or swap it. 16GB stays 16GB.

Some laptops (especially thin ones like MacBooks or ultrabooks) solder everything to save space. Others use standard SO-DIMM slots that you can pop out and replace.

Check your laptop’s service manual or look up the model on the manufacturer’s site. If they say “soldered” or “onboard,” you’re stuck. If they mention “upgradeable” or “SO-DIMM slots,” you can swap the sticks—just make sure you buy matching DDR type and speed.

It’s the difference between buying a new laptop versus buying a $60 stick of RAM. Know before you click “add to cart.”
