“My laptop broke. Why?” is one of the questions we hear most often at the lab. We’re not talking about software issues here (viruses, bad installs) — those are usually fixed with a reinstall. We mean real hardware failure.

The truth is simple: like any physical object, a laptop will eventually break. The brand alone doesn’t determine how durable a device is — comparing similarly-specced laptops across brands, the real-world differences are smaller than people assume.

Two categories of failure

Normal wear or a manufacturing defect. A laptop packs together many different components (graphics card, memory, hard drive, screen), and each has its own lifespan. The hard drive is usually the most fragile part, since it’s mechanical as well as electronic.
Overheating from use. Unlike a desktop, a laptop crams all its components into a very small space. The hotter a component runs, the faster it wears out. The biggest ally against wear is the cooling system — and that system, from being used on sofas, beds and pillows, fills up with dust and loses effectiveness over time.

How to protect your laptop

Keep it clean; avoid eating or drinking over it.
Don’t use it constantly on your lap or in bed — it blocks airflow.
The moment you notice unusual overheating, bring it in for a check before it causes permanent damage.

As for choosing a new laptop, our advice is consistent: pick the device with the best warranty length and service, provided it already covers your needs in power and storage.
