The Acer Travelmate P4 is a lightweight laptop with long battery life and a spacious 1200p display. In our review, it received four-and-a-half stars (out of five) plus an Editor’s Choice badge. According to the reviewer, you can “swap the built-in M.2 drive for one with more storage space.” The RAM, WLAN module, and battery can also be taken out. In fact, you’ll find two RAM SO-DIMM slots, which support DDR4 memory. To crack open this particular machine, you’ll need to unscrew the 12 Phillips head screws and then pry open the plate using a plastic tool. Again, for further instructions on where the RAM and SSD are inside of this machine, check out LaptopMedia’s thorough video tutorial.
