Apparently the problems/errors/failures I reported are a known problem that Lenovo has refused to address: http://reddit.com/r/techsupport/comments/ztvro4/lenovo_legion_5_t5_are_seemingly_bricked_with_no/

This is bad enough, and widespread enough, that owners of these computers trying to bring a class-action lawsuit against Lenovo: https://topclassactions.com/lawsuit-settlements/consumer-products/electronics/lenovo-class-action-claims-some-desktops-contain-severe-freezing-crashing-defect/

There is a genuine hardware problem with the motherboard, curable only by swapping out the motherboard for a non-Lenovo equivalent.

So, I am simply going to swap the motherboard, take it as a bad decision to have bought this computer, and never do business with Lenovo again.  A pity; I have used and enjoyed the ThinkPad series for a long time.  But no more dealings with a company that acts like this.

| Booted from a USB with Arch Linux on it; chroot into the now-working computer;
| ran a system update (massive: 500+ packages).  Something in there -- likely
| the new kernel and firmware -- fixed the keyboard problem.  So I didn't have
| to reinstall, just get far enough in to do an upgrade.

Wow.  Heroic measures.

| I now have a functional computer to replace the Lenovo T5.  For those of you
| keeping score, I *still* do not have the replacement MB I ordered from Canada
| Computers on 27 September.

I'm a broken record: I'd cancel the MB order and get Lenovo Warranty
service.
