Lenovo Ideapad 320-15IKB RAM upgrade

I don&understand why anyone would make a laptop with only 4GB of RAM, especially as the shipped OS is Windows 10! This memory upgrade to 8GB of RAM was seriously overdue and was preventing one of our Clients from being able to run some accounting software. A quick install of additional memory sorted things and while we had the back off we also took a look at the upgrade options available to this Levono Ideapad 320.
