User initiated hard resets can be used to reset the device if the software hangs, crashes, or is otherwise unresponsive. However, data may become corrupted if this occurs. [ 6 ] Generally, a hard reset is initiated by pressing a dedicated reset button On some systems (e.g, the PlayStation 2 video game console), pressing and releasing the power ...
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.

Restoring the software of an electronic device to its original state For the Tilian Pearson album, see Factory Reset (album). A factory reset, also known as hard reset or master reset, is a software restore of an electronic device to its original system state by erasing all data ...
Restarting a computer also is called rebooting, which can be "hard", e.g. after electrical power to the CPU is switched from off to on, or "soft", where the power is not cut. On some systems, a soft boot may optionally clear RAM to zero. Both hard and soft booting can be initiated by hardware such as a button press or by a software command.
Soft security can refer to immediate security measures, such as silent burglar alarms or motion detectors, but often refers to more elaborate social security systems such as the "moral network" [clarification needed] in a tightly knit community — for example, a cluster of friends on a busy city street.
Depending on the control unit hardware and implementation, different forms of reset can be used: 0x11 01 Hard Reset simulates a shutdown of the power supply. 0x11 02 key Off-On Reset simulates the drain and turn on the ignition with the key. 0x11 03 Soft Reset allows the initialization of certain program units and their storage structures.
Superseded by the more secure XTS mode due to security concerns. [122] XTS: XEX-based Tweaked CodeBook mode (TCB) with CipherText Stealing (CTS), the SISWG (IEEE P1619) standard for disk encryption. Authenticated encryption: Protection against ciphertext modification by an attacker
A laptop that has an embedded security switch is stolen. The security switch detects a lack of communication from a specific external source for 12 hours, and responds by disconnecting the screen, keyboard and other key components, rendering the laptop useless, with no possibility of recovery, even with a full format.
