HP also has gone insane. We got a bunch of keyboards that had 3 defective keys on the numpad. Zero, slash and enter if I remember it, bog standard keys. HP Service desk says no problem, here's 512Kb of firmware update that will fix it. And it actually did. No hardware defect, just a software bug.

I have no idea why a keyboard without much interesting extras even needs 512K of firmware, let alone why the stock firmware fails on 3 of the buttons. They're only there since 1985 or so, you'd think they got around to test the numeric pad by now
