Acer Aspire 3 (A315-42) is based on Acer’s own Aspire 5 (A515-52G). Despite them sharing pretty much the same chassis design, both laptops are very different from each other, with the main one being the use of AMD processors instead of Intel.
1. Remove the bottom plate
Again, this laptop requires its entire bottom plate to be removed, should you wish to access its internals. There are 10 Phillips-head screws that keep it in place, and after you unscrew them, you would need to pop the plate up with a plastic pry tool
After you open the device, make sure you disconnect the battery connector. It is important not to fry your hardware when you are trying to improve it. In terms of battery size, the laptop is equipped with a rather small 37Wh unit.
3. Memory and storage
What is impressive about this laptop is the amount of upgradability it offers. There are two RAM DIMMs that fit DDR4 memory modules. Additionally, you are able to put a 2.5″ SATA drive as well as an M.2 NVMe SSD.
4. Cooling system
As long as the cooling is concerned, Acer was not on the edge of technology. Nevertheless, the good old design seems to work just find with the ULV processors of AMD.
