Answer 2

Believe a former service engineer (experience in repairing at the component level, including BGA) - you should not take a used laptop.
Examples from practice:
Constant overheating (video, bridge, etc.), as a result, for replacement, for example, a video chip - you will not see any traces of repair, and the service life will be unknown. Unscrupulous services in this situation can "warm up" the chip, after that the laptop will work from a couple of hours to six months.
Replacing laptop hinges with broken mounts (without external cracks) - open the lid 300-400 times, cracks will appear (especially if it is poorly restored).
Unstable operation at high load (most often overheating, but there may be other reasons) - will appear after 2-3 hours with a gradual reduction in the interval, nothing will be diagnosed (at the beginning of the disease).
