And again just now…. Plugged in charging and then switched on.
Battery -129% ! (yes minus). No keys responding so had to hold power off. Switched back on and all fine (battery reporting 100%). Issues occur around once every 2-4 weeks. And yes for the observant, Pico2 overclocked to 378Mhz but cool and stable (with heatsink) 99% of the time….
