Updating memory on laptop
Modern Intel Ultrabooks and Apple Mac Books are becoming increasingly thin and light, and they aren’t designed to be user-upgradable.
RELATED: CPU and GPU upgrades may be possible on some laptops, but these will be harder.
Your i Mac performs a memory initialization procedure when you first turn it on after upgrading memory or rearranging DIMMs.
Use Small Outline Dual Inline Memory Modules (SO-DIMM) that meet all of these criteria: If you hear these tones, confirm that the memory you installed is compatible with your i Mac and that it's installed correctly by reseating the memory.
If your Mac continues to make the tone, contact Apple Support. The window that appears lists the total memory, including the amount of memory that originally came with the computer plus the newly added memory.
If all the memory in the i Mac has been replaced, it lists the new total of all installed RAM.
In fact, newer laptops are becoming harder to upgrade — but you still may be able to upgrade your laptop with more RAM or a solid-state drive.
It’s generally a bad idea to buy a laptop with plans to upgrade it later.
