4.How long does a laptop last?

The average lifespan of a laptop is constantly changing. As a productivity tool, with the improvement of hardware and the transformation of production application environment brought about by the development of technology, if the performance is not up to the needs of the work, we can think that this laptop is worthy of upgrading. At the same time, the daily wear and tear of core hardware and external molds also adds to the end of notebook life.Laptop owners should maintain their laptops computer regularly to increase their lifespan.

Reasons for Laptops to Be Obsolete
How long a laptop can last depends mainly on the following two reasons: the wear and tear of core components; the evolution of application software. Mainstream home notebook merchants provide a one-year limited parts warranty by default, and commercial notebooks may provide a limited parts warranty of more than three years.
In daily use, key components may fail. Even if other parts of the laptop can still work normally, the cost of repairs is too high, and the faulty laptop may be recycled as electronic waste. Or when the hardware performance and cannot meet the needs of the current software environment, we can plan to eliminate the update.
Operation and Lifespan of Laptops
Operational life can be simply understood as how long a notebook computer can operate normally. Time to run advanced programs normally by meeting the minimum system requirements.
Many older laptops are still functional after 10 years, but when you try to run the latest applications, the system no longer supports it. Applications have high demands on the system, including the performance of components such as CPU, RAM and even graphics cards. Although the notebook computer can still operate normally, its service life has come to an end.
Plan Obsolescence: The Hidden Type of Failure
Technically, rugged laptops made by well-known brands can last 5 and 10 years without any major issues. But will they retain the same level of usefulness? Not necessarily.
As you probably know, the world of software is constantly evolving, and so is hardware. Software engineers introduced more sophisticated procedures to solve surface problems and come up with better solutions. This is especially true for PC games with ever-increasing graphics demands, game dynamics, storylines, and more.
Of course, the more complex the software, the more complex the hardware is to keep up with updates. So even if a 2010 laptop runs flawlessly without much lag, we can't expect it to run games until 2021. It just can't handle software requirements.
Can we expect planned obsolescence?
Unfortunately, planned obsolescence is not always so "planned". For example, you can buy a laptop today and only find the more advanced version released the next day!
The laptop's limited upgradeability makes things worse. With a desktop, for example, you can replace the GPU card. In a laptop, it's almost impossible to do the same thing, the cost is too high!
All in all, if staying up to date is paramount to you, we highly recommend a laptop that allows easy hardware and component upgrades.
Software evolution affects laptop lifespan
Software is the foundation of the digital age.
The first generation of software was first developed in the 1940s - its instructions were written in binary code, originally used on mainframes.
However, advances in home computing technology and the development of programming languages have disrupted the breadth and capabilities of modern hardware.
While many users can remember iconic hardware like the first tablet or home computer, few look back on the classic software that made it work. Our ever-increasing demands are driving greater changes in software functionality and design. This is a developmental process.
But this will bring negative effects, the new generation of software may require more powerful hardware support to obtain better operating results, thus accelerating the replacement of computers.
Notebook component life
Laptops are made up of numerous components, and we can try to understand the different lifespans of each component.

• Battery
Similar to mobile phones and other products, batteries are undoubtedly the most easily worn components in notebook computers. After years of using notebook computers, we can often hear users complaining that the battery life has been significantly degraded. It is an option to consider by replacing the laptop's battery to extend the battery life.
Generally speaking, the battery will last up to 2 years (we used 3) before you notice any major changes in performance. But in reality, it could be shorter or longer. Actual life depends on usage.
However, any battery has a certain number of charge cycles. Beyond this charge, the battery is not constructed to store the same amount of charge. That said, users who plug and unplug their laptops frequently are more likely to damage the battery than users who keep them plugged in all day.
Before using lithium-ion (Lithium lon) technology, notebook computers used nickel-based batteries. These batteries need to be fully drained before they can be charged. Otherwise, the battery may "forget" its full potential after a short time.
For lithium-ion batteries, the opposite is true: it's best to charge the battery when it reaches 40%, and then unplug it before 80%; a concept known as the 40-80 rule. The chemistry behind it is too complex to explain here, but has been scientifically proven.

• mechanical hard drive
Before SSDs became popular, MHD (Mechanical Hard Disk Drive) was the only storage option for laptops. Since it's a lot cheaper, some low-end, affordable laptops are still being released with this technology.
While SSDs can last 10 years, MHDs will start showing signs of failure after 5 years. Just like batteries, the actual range may be longer or shorter, depending on the frequency of read/write operations.
The reason for the low service life of the MHD is related to its design. The MHD storage device reads data to the platform via a robotic arm that moves on a metal disk. SSDs, on the other hand, have NAND flash memory embedded on the circuit board. The advantage? No moving parts.
With an MHD, you can't do anything significant to extend its lifespan. Inevitably, mechanical parts will wear out and hardware will fail.
However, the SSD can be installed as a backup drive if the laptop allows it. By storing your most used programs and your least used programs in the MHD. You will use fewer MHD cycles per day, making it last longer.

• Screen
Your laptop screen consists of multiple stacked layers. For the sake of simplicity, we can say that an LCD screen consists of two parts: one that generates the actual image, and the last, the backlight, which is responsible for the brightness level.
Image-related components in laptops are usually the last used components. As long as the monitors have not suffered any physical trauma, they can live anywhere from 5 to 10 years.
The LED backlights used in newer laptops disappeared in only 10 years or so. Many older models with CCFL backlights start to lose their glow after 3-4 years.
Unlike other components, the way you use your laptop monitor doesn't really affect its longevity.

• RAM
RAM is probably the only component in a laptop that doesn't have a specific lifespan. It can last 2 to 3 years or 8 to 10 years, or as long as the motherboard can run.
However, planned obsolescence may force you to upgrade sooner than expected. Take Google Chrome as an example, it consumes a lot of RAM even with a normal Internet browser.
The good news is that upgrading RAM is fairly easy. The RAM stick is also one of the cheapest components in a laptop.

• Power Adapter
As with RAM, we cannot determine the life span of AC adapters because they rarely fail under normal use, and it is worth noting that overheating should be avoided as much as possible during use, and excessive cables should be avoided. tangles and bends.

Therefore, the service life of the notebook computer actually depends on the notebook computer hardware and the user's usage and habits. Better hardware configuration and good usage habits can delay the lifespan of a laptop. So take care of your laptop.
