Micro SD card read/write speed.
Since I am a new Linux user this was not apparent to me before. If you are booting from the micro SD port your PBP computer will only run as fast as the installed card can read+write. I wrote a few different versions of Manjaro to some old slow cards and one version to a new fast card. It is like night and day. Fast computer=fast SD card. Running Manjaro-Arm64-KDE-Plasma 20.06 fixed all my PBP problems I had with the Manjaro version shipped on the computer. No audio, no battery icon, crazy screen flicker, battery depletion during sleep, inability to read USB devices on ports A 2.0 and 3.0, are all resolved when using 20.06
