Wait, are you saying they don't offer the full HMMs and FRU list like IBM/Lenovo did/does for ThinkPads?????
IBM HMMs, or creatively named Hardware Maintenance Manuals, were written so that if all steps in the document were performed from start to end as written, the laptop would be a pile of FRUs or Field Replacement Units, so that those FRUs can be inspected, discarded, ordered, and replaced, and then the process can be done in reverse to produce a working unit.
Why - I mean I think I know why - they likely don't have enough control and/or influence over parts suppliers to be able to publicly expose those data unlike the Big Blue - but why...
Field repair by enterprise IT support was also part of Lenovo's business model. For framework repairability is a thing but it's not as important I guess.
I had an HP that also had service manuals available.
Ps Lenovo basically has two brands; the business laptops like the T, P and X ThinkPads, and the consumer stuff including some of the budget ThinkPads (I think E series). The latter don't do service manuals, have really crappy keyboards.. Just B-brand crap. They're just a consumer laptop with some thinkpad trim. Be careful with that if you think of buying one.
