Magnesium alloy going rogue - Electricity and vibrations

[moonwalkers]

Over the night, the battery, though the PBP was turned off around 80%, completely drained to 0 %.

You might wanna make sure you have the latest u-boot (search the wiki/forums if you're unsure what I mean) and the latest Manjaro kernel (I'm currently running 5.8.5) to have sleep working properly. Also check other threads in PBP forums about possible misalignment of the magnet in the lid that triggers the sensor - if you have yours misaligned your machine may not be going to sleep at all if you close the lid.
