Yeah, I'm actually surprised the hardware hasn't caught on accordingly: while it's now standard for chips to monitor their temperature (and adjust their power consumption if it gets too high), I still haven't seen anything comparable that would detect and report when the input voltage goes out-of-range (and maybe also take steps to reduce the instantaneous power consumption?). Instead, we're in the dark, forced to try to avoid the problem by over-provisioning the power supply and pray that it was enough. === Stefan
