Very few laptops fail because a component was faulty. Most fail early because of ordinary daily habits that seemed harmless.
We see the results in our workshop constantly, and the same twelve mistakes account for the overwhelming majority of them. None require expertise to avoid — just knowing they matter.
1. Using It on a Bed, Sofa or Lap
The single most damaging habit, and by far the most common.
Your laptop draws cooling air through vents on the underside and sides. Soft surfaces block them completely. The machine overheats, throttles its own performance to protect itself, and — over months — cooks its own components.
Why it matters more in Rwanda: high ambient temperatures give the cooling system far less margin to begin with.
Do instead: use it on a hard, flat surface. A laptop stand costs around RWF 20,000 and solves this permanently while also fixing your posture. If you must work on a bed, put a hard board or tray underneath.
2. Never Cleaning the Vents
Dust accumulates in cooling vents faster in Kigali than in most climates, especially during the dry season. A blocked vent turns into thermal throttling, which turns into a laptop that gets slower every month for no apparent reason.
Do instead: clear the vents every three months, and have the fans properly cleaned annually. Step-by-step cleaning guide.
3. Picking It Up by the Screen
Lifting a laptop one-handed by the display puts all its weight on the hinges and the panel. Hinges are among the most expensive and awkward laptop repairs, and a cracked panel often costs a meaningful fraction of the machine's value.
Do instead: close it and lift from the base, with two hands if it is open.
4. Carrying It Open, or Switched On, in a Bag
Putting a running laptop into a bag does two things at once: it blocks all airflow while the machine is still generating heat, and it leaves the drive and screen vulnerable to movement.
Do instead: shut down or sleep it, close the lid, wait a moment, then bag it. Use a padded sleeve — not a bare backpack compartment with your books.
5. Eating and Drinking Over It
Liquid damage is the most common cause of total, unrepairable laptop loss we see. A spill can end a machine in seconds, and business laptops with spill-resistant keyboards buy you a few seconds of drainage — not immunity.
Do instead: keep drinks beside the laptop, never behind or above it, and preferably in a closed container. If you do spill: shut down immediately, unplug, turn it upside down to drain, and do not switch it on. Get it to a technician the same day. Switching it on to "see if it works" is what turns a recoverable spill into a dead laptop.
6. Using Cheap or Wrong Chargers
A poor-quality charger can deliver unstable voltage, damage the battery, or in bad cases harm the mainboard. "Universal" adapters are a particular risk, as they often supply the wrong voltage under load.
Dell business laptops authenticate their adapters and will refuse to charge properly from a non-genuine one — worth knowing before you replace a lost charger cheaply.
Do instead: use the manufacturer's charger or a reputable equivalent matched to your model's voltage and wattage. This is not the place to save RWF 10,000.
7. Ignoring Power Fluctuations
Power interruptions and voltage fluctuations are a real hazard in Rwanda, and a laptop plugged directly into an unstable supply is exposed through its charger.
Do instead: use a surge protector where possible. One genuine advantage of a laptop over a desktop is that the battery acts as a built-in backup during outages — which is one more reason to keep the battery healthy rather than removed.
8. Letting the Drive Fill Up Completely
An SSD needs free space to write efficiently. Past roughly 85% full, performance degrades measurably, Windows updates start failing, and applications hang while saving.
Do instead: keep at least 15–20% of your drive free, permanently. Move photos and video to an external drive or the cloud. How much storage you actually need.
9. Installing Pirated Software and "Cracked" Activators
The most common malware infection route we see in Rwanda, without close competition. Cracked activation tools in particular require disabling your antivirus to install — which is the entire attack.
The cost is not theoretical: lost coursework, stolen account credentials, a machine that must be wiped and rebuilt.
Do instead: use genuine Windows, free alternatives such as LibreOffice where budget is tight, and your institution's licensing if you are a student — most universities provide Microsoft 365 free.
10. Never Restarting
Leaving a laptop in sleep for weeks means Windows never completes updates, memory never fully clears, and background processes accumulate. A machine that "gets slower through the week" is usually one that has not been restarted.
Do instead: a full restart at least once a week. This is free and fixes a surprising range of problems. More on why laptops slow down.
11. Skipping Backups Until It Is Too Late
Every drive fails eventually. SSDs are far more reliable than mechanical drives, but "more reliable" is not "permanent". The people who lose a final-year dissertation are never the people who thought it could happen to them.
Do instead: anything is better than nothing. OneDrive comes free with a Microsoft account, Google Drive with a Google account. For large files, an external drive kept somewhere else. Two copies in two places is the minimum standard.
12. Buying on Specifications You Do Not Understand
The most expensive mistake on this list, because it happens before you own the machine.
Buying "Core i7" without checking the generation, accepting "1TB storage" that turns out to be a mechanical hard drive, or paying Latitude money for an Inspiron — these cost far more than any habit above.
Do instead: run a checklist before you pay. The full 20-point checklist.
The Habits Worth Building
If you change only four things:
| Habit | Effort | What it protects |
|---|---|---|
| Use it on a hard surface or stand | One-time purchase | Cooling, performance, lifespan |
| Clean the vents quarterly | 20 min, 4× a year | Cooling, performance |
| Keep drinks beside, never above | Free | The entire laptop |
| Back up to cloud or external drive | Set up once | Your work |
Together these cost very little and routinely add two or three years to a laptop's working life.
Building Your Setup Properly
A few inexpensive accessories remove most of the risks above — a stand fixes cooling and posture, a padded sleeve protects the chassis in transit, and a proper cleaning kit keeps the vents clear.
