I haven’t seen an easily serviceable lenovo product in years. The last 3 lenovo laptops I’ve had to fix had their keyboard plastic rivited to the case, so you’d need to completely disassemble the whole thing, and get a new case if the keyboard died. One of their new thinkpads went through two motherboards before it was stable.
Their new all-in-one’s require you to remove the entire backhalf to upgrade the ram, which is basically impossible to do without damaging the screen since they don’t have any structure supporting the screen besides the case, and it’s just plastic snapped together.
I’d highly suggest never getting any lenovo product
My 2017 Lenovo Ideapad 530S’s fans whined - I had to modify the case to stop the noise. https://www.quora.com/How-is-the-Lenovo-IdeaPad-530S-15/answer/Harri-K-Hiltunen
ThinkPads are supposed to be good - well, an E480 passed through my hands. The fan whined and its control was infuriatingly aggressive on-off style, very unlike the 530S with its slooow acceleration and deceleration.
The 530S’s keyboard started malfunctioning at three years age. I replaced it even though it was riveted / melt-studded in - plastic rods poke through the keyboard, their ends melted flat and wide, forming a rivet. Some instruction video told me to cut the rivet ends off with a chisel, but I used a mini drill.
Putting the new part in, the most difficult part was to hold the keyboard pressed in its place with weights on sticks while doing a temporary re-melt of the insufficient rod ends with a soldering iron (I could have skipped that). After that, I covered the re-melted ends with epoxy for near-original strength. The repair was successful.Their new all-in-one’s require you to remove the entire backhalf to upgrade the ram, which is basically impossible to do without damaging the screen
This does not sound optimal. To be fair, most “thin and light” type laptops seem to make it difficult to upgrade components. There is always the option of going with a 17 inch laptop.
