Screw count
I was doing a tidy up & service on a neighbour's Lenovo ideapad at the weekend, the RAM and SSD were both behind panels secured by a single screw, which is nice.
If you want to do more, such as find out what's causing the ominous rattle when you tip the notebook, then the total number of screws you have to remove is 15, including 2 hidden under the SSD hatch.
At least I didn't have to remove the rubber feet like you have to on HPs
