The reasons why laptops are repaired, from the statistics of calls to our service center, are quite typical. Typical breakdowns include mechanical failures of the laptop case, charging and keyboard malfunctions, laptop motherboard malfunctions, matrix breakdowns, loops, loop in the laptop, laptop video card and laptop hard drive problems, laptop battery malfunction, cooling system problems, laptop software problems. Some malfunctions can be avoided by observing the rules and operating conditions.

In this article, we will consider the most common laptop breakdowns that customers contact our service with. We will also analyze the reasons for the malfunction of key laptop components and how to eliminate them.

Software malfunctions

The main symptom of a software failure is system slowdown, the appearance of all kinds of error messages, and the presence of viruses. Programs and the system may not load at all, constantly reboot or freeze. The user visits questionable sites, launches suspicious files and programs, works on the Internet without installing an antivirus, does not perform periodic preventive maintenance. Troubleshooting most often consists in removing viruses, changing the operating room. Reinstalling the OS doesn't always solve the problem. A possible reason for such a malfunction is a damaged hard drive. Over time, the number of broken clusters reaches a critical level, and equipment failure is inevitable. The best solution to this problem is to replace the hard drive.

To minimize software malfunctions of the laptop, keep an eye on the updated antivirus databases, check the system for viruses, update the operating system and installed programs, check files before loading.

Hardware faults can be categorized as mechanical or electronic.

Physical damage includes spilled liquids, falling laptop, impacts, damage to the matrix or keyboard, broken wires, breakdown of the power supply. Most often in a laptop, the screen and keyboard are affected.

Among the electronic ones, one can distinguish: failure of bridges and a video chip, breakdown of RAM, damage to a hard disk, screen malfunctions, damage to an internal or external power supply. Malfunctions can sometimes be eliminated by replacing the drive, as well as the hard disk, by replacing the RAM.

If vertical stripes appear on the screen, then it is necessary to replace the matrix.

Interference while playing games or watching a video indicates a malfunction of the video card. Artifacts on the screen or incorrect color rendering indicate chip damage. If the screen does not show anything at all, then this indicates a breakdown of the matrix, cable or video card.

Such malfunctions are eliminated by repairing the matrix loop, replacing the matrix itself and repairing the video chip.

If the south bridge burns out, the USB, touchpad or keyboard may not work, the laptop may turn on, but not boot. With such symptoms, repairs from the soldering of BGA components are necessary.

If there is a short circuit in the power circuit or a breakdown of the south bridge, which is responsible for starting the computer, then you will need a thorough repair, and in some cases, replacement of the motherboard.

If the laptop does not charge while connected to power. This problem can appear under such circumstances: damage with the power supply inside; distortion of the charging connector or the adapter itself. Possible repair: replacement of the power connector, repair or replacement of the power supply.

Signs of laptop contamination include increased noise, extreme heat, sudden reboots and freezes, especially when performing demanding tasks. Cleaning the cooler, motherboards, laptop case from dust is an important preventive measure and prevents damage to the heating elements. Dust, wool, debris leads to inevitable overheating and the subsequent replacement of the cooling system or, at best, the fan.

For a longer and more productive work, it is worth handling your device as carefully and carefully as possible. If there is a breakdown in the laptop, then in any case, you should show the device to a specialist.
