3. How to safely switch a computer on and off

Do not shut off your computer using the power button. This is only the power button. It is crucial that you correctly shut down your machine. Simply shutting off the power with the power button might do severe harm to the file system. Even when you’re not actively using the system, files are accessed while it is on. Remember that several processes are always operating in the background, and therefore hitting the power button does not allow for a graceful shutdown.

The genuine threat posed by blackouts, shutdowns, and using the computer’s power switch is “unexpected computer shutdown.”

Before shutting down, operating systems must execute a “shutdown sequence” to ensure that all ongoing processes have been properly terminated. A sudden loss of power might disrupt critical processes and render your computer useless.

The system files are the primary focus. Consider what occurs whenever an hard drive is writing data to a disk and it abruptly shuts off. Assuming a file being written was a crucial system file required for booting. Now that file is damaged, you are unable to start your computer without performing a lengthy recovery process.

Additionally, repeated power interruptions might degrade the physical longevity of a hard disk. The read-and-write head, which hovers above the spinning platters during operation, returns to its original position when power is interrupted. This abrupt motion may produce minute flaws that aggregate over time, hence raising the probability of a “head crash” (a malfunction that occurs when the head touches and scrapes the platter surfaces, effectively destroying the hard drive). Power interruptions may potentially cause catastrophic damage to solid-state drives. Problems might vary from data corruption to complete system failure.
