    What kind of SSD is it? I searched online but they all look similar. I want to upgrade to 1TB SSD but not sure which one to buy. Please guide me. Thanks.

      Maria, this is PCIe NVMe M.2 solid state drive.
      Here’s one you can use Samsung 970 EVO Plus SSD 1TB – M.2 NVMe.

    So I have read a lot of different assemblies for opening the back of the laptop. I lost a few screws to the back and I am wondering, is it Torx T4 or Torx T5 to replace the screws holding the bottom cover.
