Diagnosing and fixing failure to wake from suspend(Diagnosed HW issue)
#1
I amusing the latest Mobian trixie on my PPpro, slightly modified with an older kernel as this seems toavoid the non-working wake button issue. https://forum.pine64.org/showthread.php?tid=19940

My issue is that unless I run the caffeine toggled on my phone falls into a suspend coma nad no charge cable, phone call, or wake button brings it back.  If the indicator LED was blinking it will continue,it might have even been one case where an audiobook was running and I couldnt get it back thoug that might be the intermittent non function of the wake/sleep button in the OS(holding still triggers a shutdown).

I do NOT have a serial cable to get the logs right at the fall into suspend coma.

I opened my PPpro and removed/reattached the ribbon cables easily accessed after removing the extrenal screws, this has fixed the bootup issue and I am sure the sleep --> coma problem too.
(edit)
And now after 30 min we are back to needing to smakc the Pinephonepro to boot after doing a pwr/wake button hold to hard shutdown; the coma after suspend is still a problem, it is probably the ribbon cable but what to do now other than try what I did again.

It turns out the narrow RF shield at the top left of the PCB to the left of the silkscreened word "Pinephonepro", below the two rectangular camera connectors, and above the square modem/CPU RF shield has come loose, solder joint failed.  when the shield is pressed down the PPpro can boot and when not present no boot is possible, once bootup starts it is not needed....
I might have to just buy a new board for my PPpro.....
(edit)trying to fix using a paper shim to hold the RF cover tight. doesnt work..
Maybe I can find a hot air gun and fix this as there are so many small parts I dont want to touch with a soldering iron and glob with solder.
This loose RF shield is also why my PPpro can't ever exit power saving mode.

Does anyone have a PinePhone pro and hopefully a pinephone keyboard(mine was stolen) they want to sell? private message me please.....
