unsuccessful re-install of OS for PineBookPro

[Valiance]

14" PineBook Pro, purchased in late 2022

I stood up the desktop and had it just starting working
I wanted to upgrade to the latest Manjaro ARM kde Plasma for PBP v22.12 
as I followed the directions, my system only gets to green power LED, no screen, no sound  - I'm stuck.
I do not recall interrupting the process, although at this point I am not ruling it out.
I would like to get the PBP laptop stood up to a desktop environment for Plasma/Manjaro

I found the switch for the eMMC to allow it to boot microSD and got an install stood up.    I cannot access the SSD however.  still working on it.

SSD ??? Do you mean emmc or nvme ?
If emmc, it it is just a question of timing, when to flip the disable switch back to enable
It has to be long enough for the 3rd choice, SD to start loading idbloader (& then uboot,, from SD)
but not too long, before uboot finishes its device enumeration
So.. press pwr button 1 sec, wait 2-3 sec, flip switch
lsblk to see if you got it right, emmc has the boot0, boot1 sections on it (rk3399 does not use these, ignore)
Or, there are the unbind/ bind commands, search forum
If you mean nvme, usually because it wants too much power,
I don't know the commands to put it to power state 2

Thank you.  Switching the eMMC worked. Had a little struggle with when to switch it back, but got it figured out.
