Ummm, sorry, no.
Per the title Microsoft’s partner was more AMD, not Lenovo. You probably already know, but IBM is the one who basically gave their PC division to the Chinese for nothing, and the Chinese renamed it Lenovo. When IBM was questioned on it, their response was that they had more employees outside the US, than in it at that point, as if that was any sort of justification.
IBM was the third largest PC manufacturer in the world at the time, and Lenovo is still probably somewhere close. There was a Freeper back then who worked for IBM that got extremely emotional and defensive whenever it came up. Can’t remember the name, but haven’t seen him since.
