You can't add ram. It's soldered non expandable. But lovely system. Good IPS display. Only m.2 sata ssd supported.
Amazon says its 2.3 Kg And reviewed here https://laptop-review.co.uk/medion-akoya-s3409-30021747-review/ "Weighing just 1.3kg"
Can anyone see the weight of this laptop?
Good price for an ultrabook; a real shame its only got 4GB RAM but otherwise hot. (Guessing that adding more memory is not straight forward.)
