The other significant kind of power supply regulation may be the linear regulator, which generally suppresses lower-frequency input sound and ripple by eighty-a hundred dB. Meaning a bit of enter bumpiness will almost certainly occur out of the filtering and regulation levels as just a bit of fuzz.
the Personal computer — would spontaneously reboot. Anything else linked to the "battery" retailers would not sleep. It had been so Strange that I basically wrote an Arduino program at one point to log "live-ness" around various weeks to try to detect power drop-outs.
