Old hardware, new life: How Windows laptops can last longer

Millions of laptops end up as electronic waste every year - even though they are still technically sound.

According to the Federal Environment Agency, the production of a notebook causes up to 70 percent of the total CO₂ emissions of its life cycle. Each additional phase of use therefore saves measurable resources.

Despite this, many users replace their device as soon as it starts up more slowly or the battery starts to weaken. However, the service life can be significantly extended with a manageable amount of effort - and usually without having to dig deep into your pocket.

A proven first step in this context is to replace the hard disk with an SSD. The difference is immediately noticeable: a system that previously took almost a minute to boot up now starts in just a few seconds. This is also confirmed by numerous practical tests carried out by specialist magazines. The change has a huge impact on overall performance.

Memory also deserves attention. If this is doubled, many older Windows devices will experience a significant boost in multitasking and browser use.

Upgrades of this kind are generally straightforward to carry out. A small Phillips screw, a careful twist of the wrist - and the inner workings are exposed. If you are unsure about doing the work yourself, specialist companies that specialize in older models can help. They can also carry out more complex work, such as replacing defective screens. A laptop display repair is in many cases the more economical and environmentally friendly solution compared to a new purchase, provided that tested spare parts are used.

However, the hardware alone does not determine the service life. The operating system also plays a key role.

Windows 10, for example, still receives security updates so that it continues to provide a stable foundation. Clean system maintenance also ensures speed. Users who regularly check the autostart, delete temporary files and remove rarely used programs reduce the load on their RAM and CPU.

A helpful practical tip: In the energy settings, the processor performance can be slightly reduced in mains operation without affecting the work. This reduces the temperature inside the device, which in turn measurably increases the service life of components such as the mainboard and battery. Such small adjustments can quickly add up and have a major effect, especially on laptops that are used on a daily basis.

An overheated laptop works slower and ages faster. This is usually caused by dust that has settled in the ventilation slots over the years. If you occasionally clean the device with compressed air or have the fans professionally cleaned, you reduce the risk of expensive consequential damage. Replacing thermal paste on the processor and graphics unit can also significantly reduce the temperature. This measure is offered by experienced workshops.

The batteries of the devices lose capacity over time. This is technically unavoidable, but it can be mitigated. A charge level of between 20 and 80 percent is considered ideal. In addition, replacement batteries are still available for many older models, for example from the original manufacturer or certified partners. If these are installed professionally, several years of additional service life can usually be gained.

A study by Deutsche Umwelthilfe shows: Targeted repairs and upgrades extend the average use of a laptop by two to three years. This saves money, reduces electronic waste and also conserves raw materials.

Users who look after their device, maintain it regularly and replace individual components will benefit from a loyal companion that will continue to work reliably for years to come.

Old hardware doesn't have to be a problem. With a little attention, it becomes an impressive example of how sustainability and modern technology don't have to be opposites.
