(1) Brilliant on Lenovo's part. A ram slot woulda cost what a 1.00 extra in the production. As usual manufacturers building obsolescence into their designs. Apple is the worst offender in this ripoff. Update (01/13/2019): No ram slot unequivocally = no upgrade. It's like a chromebook 100+ dollar disposable laptop. If you doubt me go to www.crucial.com and I'll be vindicated.
