Once they were first introduced, laptops were often underpowered, expensive, and high. As technologies have improved, modern laptops and mobile computing offer performance on par with today's most effective personal computers and therefore are lightweight, which makes them very mobile. With portability and all the extra features, though, problems can happen that that may leave a laptop broken.
The most common hardware fault found in a laptop involves its source of energy. Many people are acquainted with a predicament where the computer fails to turn on after many attempts. In the beginning, it might appear like the battery needs to be recharged, but even plugging the pc into a wall outlet does not appear to help. Chances are that the laptop includes a bad power adapter or a bad power jack. The power jack on a laptop is susceptible to damage due to the frequency of its use. With users carelessly plugging and unplugging the AC adapter, the jack can get damaged as the solder welds wear out, preventing laptops from receiving external power. When the batter runs out, the laptop won't function and cannot be recharged.
Another laptop repair issue that owners face is overheating. Overheating is caused by a faulty fan that reduces or by blocking the airflow in to the computer. Laptops are cooled by small fans that switch on and off, bringing in cold air in the surrounding environment for cooling from the electronics inside. When the fan malfunctions and stops getting air, the components in the laptop such as the CPU and hard drive may overheat, causing the computer to shut down intermittently. Furthermore, laptop overheating can occur if airflow in to the system is blocked. One common cause of this is resting the computer on a soft surface such as a pillow much more use. To avoid this, laptops must always rest on the flat, hard surface when turned on.
Laptop PCs are built for portability, however in the course of being taken a multitude of locations, they can also suffer a lot of abuse. Bumps or falls are a major cause of laptop failure. Impacts are notorious for causing hard disk malfunctions. Sudden jolts or impacts and disturb the fragile magnetic platters or reading head in a hard drive, making it unreadable. When this happens, the computer will still turn on, but may begin to create clicking noises and fail to boot towards the operating system. An alert message will sometimes show up on the screen telling the owner that the hard disk failure has occurred. When this happens, the drive must be replaced.
Finally, some laptop faults are software related. Many users complain regarding their computers being slow or acting in strange ways. Sometimes these complaints tend to be more sign of a software problem as opposed to a hardware fault. Common causes of software issues include bad drivers, incompatible software, or viruses. It's important to keep drivers and also the operating-system current, while also performing routine virus scans and disk defragmentation.
