Lapbookpro ram upgrade

How to upgrade the ram of lapbook pro from 8gb to 16gb? And what spec of ram need and capacity thanks

Realistically there is no way to upgrade the ram. The ram is entirely soldered to the board, so you’d need to get the actual DRAM chips themselves, desolder the existing 8GB, and solder in the 16GB. Unless you’re HIGHLY skilled at the small solder contacts that the motherboards use, there’s more of a chance of killing your board (and thus your laptop) then there is of successfully upgrading the ram.
