Main functions of a hard reset:
- Resolving device freezes: When a device becomes unresponsive due to program crashes, memory overflow, resulting in a frozen screen or unresponsive buttons, a hard reset is the most direct way to restore functionality.
- Freeing up stubborn resources: When some programs malfunction, they may occupy a large amount of memory or hardware resources that cannot be released through normal operations. A hard reset can forcefully clear these resources.
- Emergency startup: When system files are slightly damaged, preventing the device from booting up normally, the hard reset process of some devices can bypass part of the self-check and attempt to start the device.
Precautions for hard reset:
Potential data loss: Since programs are not shut down normally, temporary data such as documents being edited and unsaved operations will be directly lost.
Risks of frequent use: Long-term or frequent forced interruption of operation may cause bad sectors on the hard drive (especially mechanical hard drives) or damage to system files.
Different operations for different devices:
Computers: Usually, press and hold the power button for 5-10 seconds.
Phones/tablets: Mostly a combination of "power button + volume button" pressed and held (the combination varies by brand).
