Product ref: only N14C4WH64 (to read this reference, it is on the sticker of the bottom of the computer). The OEM may be Teclast (China). Note: the storage is eMMC (not replacable), but the laptop has a microSD card slot where you can install a OS (this is what I use). sudo dmidecode | grep "System Information" -A 2
