![]() While laptops aren't as powerful as a full PC, they're far more usable when the power drops out than a computer.Download Storm It - Tweetstorm on Twitter PC for free at BrowserCam. If you instead want to continue working through a power cut, why not use a laptop? Laptops entirely avoid power outages it switches to the battery when the electricity cuts out.Īs such, if you're in an area that suffers from power cuts frequently, it may be worth changing to a laptop. In addition, UPSs can sound an alarm to alert you of an outage or even tell your PC to shut down immediately. However, those few minutes give you plenty of time to shut down your computer manually to prevent damage. This means it's not a great solution if you want to continue working through an outage. It's important to note that a UPS unit only powers your electronics for a few minutes. A UPS will be a strong investment if you live in a building or location that frequently experiences outages, surges, or both. UPS devices can also come equipped with surge-protected outlets, making them a useful two-for-one purchase. As per Kingston, many solid-state drives have power-loss protection (PLP), but "Early generation SSDs were not as resilient to sudden power loss as today's models." So, if you have a much older solid-state drive and you live in an area with known power grid issues or that experiences extremes in weather, upgrading your SSD could be worthwhile. Issues can range anywhere from data corruption to total malfunction. Solid-state drives can also suffer catastrophic damage from sudden power cuts. This sudden movement can cause tiny imperfections that accumulate over time, increasing the likelihood of a "head crash." This is when the head touches and scrapes the platter surfaces, effectively destroying the hard drive. This is because the read-and-write head, which hovers over the spinning platters during operation, snaps back into its original position upon power loss. Power cutting out mid-save may corrupt your work.įurthermore, frequent power outages can reduce the hard drive's physical lifespan. If you don't get into the habit of constantly saving your work, a power cut could set you back to square one. ![]() If you're lucky enough that your system files are unscathed, you may still lose vital work. ![]() This is when an appliance receives more electricity than intended for at least three nanoseconds. On the other side of the spectrum, there's the power surge. ![]() There's also load-shedding, also known as rolling blackouts, which are intentional blackouts designed to protect large electrical grids from becoming overwhelmed, leading to a full blackout. These can be intentional to reduce electrical loads and prevent blackouts, though they can also be unintentional. If you've ever seen your lights dim for unknown reasons, it was probably due to a brownout. These tend to occur due to issues beyond your control (e.g., power station disruptions, damaged electrical lines, etc.), but sometimes they can be self-inflicted (e.g., by shorting or overloading circuits).Ī similar issue called a brownout is when your electrical voltage experiences a temporary drop without fully blacking out. When power completely shuts off, it's known as a blackout. Both too much and too little power can cause problems. Electrical currents can ebb and flow, dipping above and below what's ideal. The electricity flowing through your home is not constant.
