Updating memory on laptop
When you build a desktop PC yourself, a typical case will come with plenty of room inside.You can open it by twisting a few screws and get easy access to all the hardware in the case.* Memory is not removable by users on i Mac (21.5-inch, Late 2012), i Mac (21.5-inch, Late 2013), i Mac (21.5-inch, Mid 2014), i Mac (21.5-inch, 2017), i Mac (Retina 4K, 21.5-inch, 2017), and i Mac (Retina 4K, 21.5-inch, 2019).If the memory in one of these computers needs repair service, contact an Apple Retail Store or Apple Authorized Service Provider.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.
Some laptops can be upgraded fairly easily, but do your research here.
Core Duo i Mac computers should operate normally with a single DIMM installed in any slot, top or bottom.
("Top" and "bottom" slots refer to the orientation of the slots in the pictures below.
You’ll need to make extra sure to buy compatible components that will fit your laptop and be supported by its BIOS.
Different CPUs and GPUs generate different amounts of heat, so your new components may generate too much heat for the fans and cooling solutions that came with your laptop to handle. So, can you upgrade your laptop’s RAM or install a fast solid-state drive? Look around online to see if your model of laptop is easily upgradable and if other people have upgraded its components successfully.
If you’d like to upgrade the memory in one of these models, an Apple Authorized Service Provider can help.
