Abstract
Diagnostics and boot up for AV hardware and software of a computer system of an autonomous vehicle may be performed based at least on receiving a shutdown or power off indication, then a computing state of the computer system may be suspended with the computer system entering a low-power mode. The suspended computing state can be rapidly restored without requiring a reboot and diagnostics for key-on. To ensure the integrity of the saved computing state, the computer system may exit the low-power mode, rerun the diagnostics, reload the programs, and then reenter the low-power mode. Restoring the suspended computing state may be triggered by a user inserting an ignition key, pressing a button to turn on the vehicle, opening a door to the vehicle, remotely unlocking the vehicle, remotely starting the vehicle, etc.
