But it is also important to take into account the desired lifespan of the equipment, because the possibilities of laptop extension and from a PC they are completely different. While in a PC we can replace any component, from the case to processor passing through the foodmemory, hard drive, heat sinks and so on, on a laptop the options are very limited.
As technology advances, laptops have become smaller, which has come at the cost of expansion options. A few years ago, when laptops were big and heavy, many manufacturers even allowed the processor to be replaced with a more powerful one, allowing extend useful life of these.
Nowadays, if we are considering buying a laptop, first of all it is important to know which parts of the equipment can be replaced in case they stop working or we want to expand its capabilities, this is i.e. its performance.
RAM memory
The more RAM a computer has, whether laptop or desktop, the smoother it will run. Most laptops except ultrabooks where all elements are soldered to the board and equipment with processors with ARM architectureyou have the possibility to add new memory modules via one or more modules.
Some models include the soldered memory to the motherboard, limiting expansion options to a single module. When buying a laptop, it is important to know if the memory is soldered to the motherboard or if it is independent, because if it is soldered it can limit the possibilities for expansion.
Storage
Most of the equipment that can be found on the market includes 256 GB or a maximum of 512 GB, space which at the first change may not be enough. As with RAM memory, most equipment arriving on the market allows you to replace the SATA or SSD storage unit. PCIe M.2 SSD for one with greater capacity.
If it is an ultrabook, the disk will most likely be soldered to the board, but it may offer the possibility of adding an additional storage disk in M2 format.
Connectivity
If the equipment we usually use is a few years old and we start to have connection problems to wireless networks that use security protocols not compatible with our laptop, there is no need to throw it in the trash.
The connectivity module of a laptop, which includes support for Wi-Fi Yes Bluetooth is another component that we can quickly replace with a module that offers WiFi 6 and also Bluetooth to connect wireless devices.
These types of modules can be easily replaced in a laptop, although it is necessary to disassemble the entire back of the device because it is not accessible through a cover like RAM and storage are. Once, it is important to note that this option is not available on compact computers like ultrabooks and computers with ARM processors.
