Why it's important to unplug your PC during a power outage
Unplugging a computer during a power outage is crucial because voltage spikes upon power restoration can severely damage sensitive internal components. Simply turning off the PC is insufficient, as electricity can still travel through the connected wiring to cause harm. Experts recommend using surge protectors or uninterruptible power supplies and waiting a few minutes before reconnecting devices after the grid stabilizes.
- ▪Power surges occurring when electricity is restored are often more damaging to computer hardware than the initial outage itself.
- ▪Sensitive components such as motherboards, RAM, and SSDs are particularly vulnerable to voltage spikes that exceed standard 120-volt household levels.
- ▪Sudden power loss can corrupt unsaved files and damage the mechanical heads of hard disk drives.
- ▪Uninterruptible power supplies (UPS) provide both surge protection and battery backup to allow for graceful system shutdowns.
- ▪Users should wait several minutes after power restoration to ensure grid stability before plugging electronics back in.

News Computing Why it's important to unplug your PC during a power outage Unplugging your PC during a blackout might be exactly what saves it. By Gabriela Vătu Sept. 21, 2026 8:30 pm EST Om.Nom.Nom/Shutterstock Add Engadget on Google: Preferred Source Google Discover Power outages don't usually come with a schedule. And when one hits, most people focus on finding the nearest flashlight rather than thinking about their electronics. But if your PC is still plugged into the wall when the lights come back, it could be in danger. Many assume that a PC (unwillingly) shutting down is enough to keep it safe during an outage, but it isn't. Even a powered-off computer remains connected to your home's electrical wiring, and that connection is exactly how damage occurs.
