A graceful shutdown using the power button is perfectly fine cause the OS will shutdown it system files gracefully however if your office and home and have frequent power instability. There are many harm it can do to your system and data.
A power power outage can reduce a hard drive’s physical lifespan. The read-and-write head, which hovers over the spinning platters during operation, snaps back into its original position upon power loss. This sudden movement can cause tiny imperfections that accumulate over time, increasing the likelihood of a “head crash”: a malfunction that occurs when the head touches and scrapes the platter surfaces, effectively destroying the hard drive.
Solid-state drives can also suffer catastrophic damage from sudden power cuts. Issues can range anywhere from data corruption to total malfunction.
Power outages normally comes with power surge which can cause serious damage to your computer components. To protect your data against such outages check our UPS sections here.
