When it comes to laptop repair, few things are worse than a dead laptop. Once a laptop does not turn on or respond in any way, it is difficult to even diagnose any kind of problem. Here, we will explore some common issues that can lead to a dead laptop if not addressed ahead of time, in the hopes that you can avoid a costly repair or replacement in the future.
The most common cause of a “dead” laptop is the laptop systemboard or motherboard. Because the systemboard controls input and output of data to and from each component, and also controls the power to each component, a problem with the systemboard often means a laptop will not respond when turned on. Many problems are caused by overheating, which can often be avoided by periodically cleaning dust from all fans and vents, and keeping good ventilation to the laptop at all times.
Many dead laptops are caused by a bad battery or a faulty AC adapter. If the laptop is not receiving power, or is receiving the wrong voltage, for example, it may not even turn on or respond. Check the AC adapter periodically for damage to cables or the transformer, and test your battery with battery monitoring software to avoid these problems in the future.
Less frequently, a dead laptop can be cause by a failing laptop CPU. This can also be caused by overheating, as the CPU creates a high amount of heat inside the laptop. Most often, however, a CPU problem manifests as a laptop that crashes or gives errors, rather than one that is dead. If you suspect that you may have a CPU issue, its best to take the machine into a repair center for diagnosis, as they will have the tools and parts to address the problem you are having with minimal investment on your part.
Defective laptop memory is not often directly a cause of a dead laptop, but memory that fails or is inserted incorrectly can sometimes result in damage to the systemboard, which can cause the laptop to cease functioning properly. Always be sure you are inserting memory correctly by lining up the notch and pins, and ensure that the memory is compatible with your specific model.
By keeping these common problems in mind and keeping an eye out for them, you can often avoid a major problem before it begins, saving yourself the time and money of a costly repair. Spending just a few minutes on prevention can help your laptop to have a much longer and more stable life.
