On the screen, if working, will be the Sad Mac icon, along with two hexadecimal strings, which can be used to identify the problem. Some Macs made around this time do not use a death chime like Macs made prior to 1987, but retained the same format as those that used the death chimes, such as the presence of the Sad Mac icon and two hexadecimal ...
On switching the computer back on, the computer is restored to its state prior to hibernation, with all programs and files open, and unsaved data intact. In contrast with standby mode, hibernation mode saves the computer's state on the hard disk, which requires no power to maintain, whereas standby mode saves the computer's state in RAM, which ...
A device with AOD enabled keeps a limited portion of the screen on during sleep mode.An Always-On Display may display a set of recent push notifications in place of a notification tone or LED signal, as well as information such as the time, date, and battery status of the device; they often may also be configured to also show various types of notifications as they arrive, or screensavers.
On the other hand, a system in sleep mode still consumes power to keep the data in the RAM, and thus cannot last indefinitely, as hibernation can. Detaching power from a system in sleep mode results in data loss, while cutting the power of a system in hibernation has no risk; the hibernated system can resume when and if the power is restored.
Power gating is a commonly used circuit technique to remove leakage by turning off the supply voltage of unused circuits. Power gating incurs energy overhead; therefore, unused circuits need to remain idle long enough to compensate this overheads. A novel micro-architectural technique [10] for run-time power-gating caches of GPUs saves leakage ...

A switchable power strip or power bar. Timers can be used to turn off standby power to devices that are unused on a regular schedule. Switches that turn the power off when the connected device goes into standby, [30] or that turn other outlets on or off when a device is turned on or off are also available. Switches can be activated by sensors.
