Cannot boot up after hours off

[Jeremiah Cornelius]

I've probably posted about this here and there, and I am still struggling with this. If anyone has any ideas, I would really appreciate them.

After a long power-off time (let's say overnight), I cannot simply boot up.
LED stays off, no UART output.

If I keep trying, it eventually kicks in and boots up.
After that initial hurdle, there's absolutely no problem with subsequent shutdown > boot up cycles, works like a charm.
Currently running an up-to-date Manjaro build. No other Manjaro user seems to have this issue. (or maybe nobody bothered responding over there)

Might be worth noting that for the life of me I just cannot get this thing to reboot properly. (If I try a reboot, I always have to turn it off by long pressing the power button, then boot up)

This is absolutely driving me insane. Instead of normally powering the laptop on, I have to go through several voodoo steps and prayers before I can do anything with the laptop... Should I just go ahead and engage Pine support, perhaps going for a replacement?

The symptoms are not conclusively indicating an issue with hardware. I'd try to see if this is reproducible with a different OS distribution booting from alternative media. 

I have experience with alternative machinery and different OS's that presented similar problems - such as Macbooks running Debian, and NetBSD on SGI hardware.  
If the native OS behaved, I could rule out the machine itself.

If you are able to reproduce this with the PinebookPro Debian on SD, then you can zero in on this being a defective unit.
