Had a similar issue a few months ago: Wasn't using the Pinebook Pro at all for about half a year and it wouldn't turn on anymore.
Apparently the battery was completely depleted and trying to charge it with the barrel wall charger made no difference.
Searching this forum i stumbled over the advice to charge it overnight via USB-C only and this finally did the trick for me.
