Power outages pose a greater risk to your devices when electricity is restored than when it cuts out. Unplugging your PC during an outage prevents damage from power surges.
When the power returns after an outage, electrical surges can fry sensitive components in your computer. This surge—often called inrush current—can exceed safe voltage levels and permanently damage your motherboard, power supply, and other internal hardware.
The risk is real because power restoration is rarely smooth. Fluctuating voltage during grid stabilization creates unstable conditions that electronics cannot tolerate.
What to do:
- Unplug your PC at the wall outlet during any outage
- Unplug monitors, routers, and other connected devices
- Wait 5-10 minutes after power returns before plugging devices back in
- Consider using a surge protector for ongoing protection
This simple step costs nothing and takes seconds. For added protection, a quality uninterruptible power supply (UPS) can automatically shut down your system safely during an outage and protect against surges when power returns.
Hard drives, SSDs, and RAM are particularly vulnerable to power surge damage. Taking precautions now prevents costly repairs or data loss later.

The performance gap between wired and wireless gaming mice has largely closed. Modern wireless technology now delivers competitive speeds and reliability comparable to their wired counterparts.
Saudi Arabia is entering the automotive market through Ceer, a new electric vehicle brand backed by the Public Investment Fund and Taiwanese manufacturer Foxconn. The joint venture will launch with two EV models.
Wired charging outperforms wireless charging when it comes to long-term battery health, primarily due to heat generation. Understanding the tradeoffs between convenience and battery degradation can help users make informed decisions about their charging habits.
