I bought a refurbished L15 lenovo laptop - Model 20U7S01600
What I learnt from my previous two laptops. You can lookup the serial number and see the first activation date: 2020-11-16 / end of 4 year warranty 2024-11-15
It is a bit annoying to click around until you find the specs.
Most interesting DRAM - lenovo part number: 5M30V06802
Most intersting mainboard - lenovo part number: 5B20W77594 (this makes it clear two dram slot - replaceable)
This is the third laptop I bought from that refurbish company in Austria. Everytime the bios was never updated. I assume the device was shipped with 1.12.
Uefi list: Installed 1.12 / available 1.36

edit: Left speaker - near the ryzen pro sticker has some sort of distortions when changing the volume level in windows 11 pro.
edit 2: I have to wait a few days for an answer for my email regarding the left speaker. I do not see much difference between the grading. I purchased the worst grading called "fair". There is the better "gut" and there is some other best grading. Except a few very small scratches I do not see anything. I hope I get the speaker. I have to open the device anyway for thermal paste replacement. I also have a corsair mp600 pro 1tb m2 nvme lying around with stock cooler. No idea about the warranty for the corsair nvme - but the cooler has to go when I want to replace the nvme in that notebook. I will have to use some sort of cloning software also - maybe clonecilla or something like that. It makes selling the device or sending the device for repair easier when the original drive is pulled out and replaced instantly. I just initialise windows to check if everything "works" with a quick check.
