About keyboard:
... I realized I did not know where keyboard firmware is actually located -- if it's on the main board then it's wrong since it was for ISO keyboard. If firmware is directly on the keyboard then newly arrived keyboard was completely broken. Fortunately installing new firmware helped (after few attempts out of which few ended up in errors). Note that installing firmware is extremely complex if 1) you cannot attach external keyboard (no USB2 devices), 2) your WiFi connects after logging in (no SSH) 3) you cannot login since you don't have any working keyboard.
As for good news NVME adapter worked fine from the start with WD Blue SN550.
One thing is for sure: if I every open up PBP again, that would be just for replacing daughter board. Everything inside is just way too fragile.
Thanks for your post. It's very close to home for me.
I just received a replacement ANSI keyboard because the original board apparently failed outside of warranty. Looking at the keyboard now I'm guessing that the failure is in the firmware you alluded to.
Do you have a link to instructions on how to update the firmware? Maybe some notes you'd be willing to share?
I can get logged in and slowly do some keyboard input so I may be able to do a firmware flash.
Also, you alluded to using an external USB keyboard. Is that talked about anywhere online?
I really don't want to transfer all of the PBP's components to the new keyboard - I have essential tremor. If I'd done my homework thoroughly I would have cut my losses.
Thanks
