I've recently bought an Acer Nitro 5 (Model AN515-54) with an i5 from 9nth gen, a GTX1650, 1 Tb HDD+128 GB SSD and 8 Gb of RAM. However, I'd like to improve this last point, if possible, doubling it. Moreover, on a sticker that came with the laptop, it indicates me that it has Dual M.2 support + 1 HDD slot. I'd appreciate some help in regards on how much RAM can I add, in what way and what other things is possible for me to improve. Thanks in advance.
