5 Bad Habits That Are Destroying Your PC
Monday, September 7, 2020 at 12:55AM 1. Leaving Your Laptop on a Plush Surface (and Other Overheating Problems)
Heat is your computer's mortal enemy. If your computer gets too hot, the processor may slow down, throttling itself to keep temperatures reasonable, or even shutting down completely. Running at high temperatures for extended periods can reduce the lifespan of your processor, fans, and battery as well—not to mention make your computer loud and sizzling to touch.
For desktop computers, the solution is pretty simple: make sure your case has adequate airflow, with enough vents and fans to keep cool air moving through the components. That means keeping it out of tight cabinets and other spaces that trap heat. You probably want to clean out the dust once in a while with an electric duster (more on that below). And if you’re overclocking, take extra care to watch those voltages and temps.
Laptops, on the other hand, require a bit more care. Their portability leads to a lot of bad habits, like putting it on a blanket or other plush surface. This blocks airflow under the laptop, and potentially through the laptop (if the blanket covers the fan vents).
When possible, use your laptop on a flat surface (where the rubber feet usually raise it up off a desk), or at least make sure your lap is free of blankets and other things that can block airflow. Lap desks are a good way to ensure things stay cool.
Other than that, the same rules apply to laptops as desktops: Don't leave it in hot places (like a car on a sunny day) and blow out the dust once in a while.
2. Letting Dirt, Dust, and Liquids Run Wild
All computers accumulate some dust over time, heating up the components and making those fans work harder. While cleaning it regularly can help, you also want to prevent stuff from getting into your computer in the first place.
For example, cigarette smoke and pet fur will exacerbate those problems, and putting your desktop PC on the floor will ensure more of that dust, hair, and debris will get sucked into the intake. And if you have carpet on your floor, you’re probably blocking the power supply’s intake fan. Keep your computer on a desk or other riser, if at all possible, and make sure there are filters on your intake fans.
Secondly, don’t eat or drink near your PC, or at least take some care when you do. Getting crumbs in your keyboard is not only disgusting, but it can damage the switches or make certain keys harder to press. And I’m sure you’ve heard enough horror stories about people spilling coffee on their laptop, which can straight up destroy the machine.
Even well-intentioned moves, like cleaning your screen with Windex, can introduce liquid where it shouldn’t be (also, Windex is too harsh for your monitor). Spray your gentle screen cleaner on a microfiber cloth, not on the screen, and don’t go crazy—a little goes a long way.
3. Handling Your Laptop Carelessly
Again, while desktops have the luxury of sitting comfortably in your office, laptops are subject to all sorts of abuse. I've seen people pick up the laptop by its display, open the hinge from one side with way too much force, and toss the laptop onto the couch from the other side of the room. (Sure, a couch is rather soft, but one day, you're going to miss and hit the table or floor, and you'll be sorry.) I've even seen people use closed laptops as a coaster for their drink, which makes me grit my teeth in anxiety.
Laptops are meant to be portable, and some can be pretty durable, but the more you abuse it, the more likely you are to damage something. At best, you'll just have to deal with a worn-out laptop hinge or a crack in the casing. But if your laptop has a traditional spinning hard drive instead of an SSD, tossing or shaking the computer—especially if the drive is active at the time—can even cause its head to dislocate or touch the surface of the disk. It isn't common, but if that happens, you're going to have a bad day, especially if you haven't backed up your data. Your laptop is an expensive piece of property: treat it as such.
4. Mismanaging Your Old Battery
Just because your laptop's battery starts with "eight hours of battery life" doesn't mean it'll stay that way forever. Batteries degrade over time—you may get eight hours on a full charge when you first buy it, but after a few years, that may degrade to six or seven hours. There's no escaping this decline, but you may be degrading it faster than necessary if you always run your laptop down to 0 percent.
To prolong your battery's long-term health, it's best to perform shallow discharges, and recharge it frequently. Don't over-stress about this, of course—if you're on a plane and need to work, an occasional discharge won't kill your battery—but over time, it's best to err on the side of charging regularly than running it down to empty.
You should, however, stress out if your battery is swollen. If your battery is bulging so much that it’s pushing against the case of your laptop, creating a gap between the panels, you need to stop using your computer now and (safely) replace the battery, lest you encounter an explosive failure.
When you replace the battery, don’t buy a cheap knockoff from eBay—buy it from the manufacturer or a respected third-party store. Low-quality batteries will, at best, not hold a charge very well, and at worst, can be dangerous. The same goes for third-party chargers—just stick to the manufacturer’s official offering or, in the case of laptops that charge over USB-C, a certified USB-PD charger.
5. Wasting Time on Unnecessary Maintenance
Back in the days of Windows XP, when hardware was limited and computers were slow, PC maintenance may have made a difference. But these days, deleting unused and temporary files is unlikely to give you a noticeable speed boost. Many "PC Cleaning" utilities are scams meant to scare you into buying their product—and the free, less scammy ones are still unnecessary most of the time.
Furthermore, certain types of "maintenance" may actually be harmful. Registry cleaners provide almost no benefit, but if they delete a registry entry you actually need, they can actually cause problems. Similarly, these new "privacy" apps that claim to stop Windows 10 from "spying" on you can break certain features without you knowing why.
The internet is full of people confused about why something stopped working, only to find that it's the fault of one of these tools. You're better off going through Windows 10's settings, learning what they do, and tweaking them yourself.
If you want to clean up your hard drive, use Windows' built-in Disk Cleanup utility and delete any movies, music, and other files you aren't using. And if your computer is running unbearably slow, try removing startup programs or resetting your PC—if that doesn't work, it's probably time to upgrade your hardware.
