The display and keyboard are the components of a laptop that tend to have a shorter lifespan. While replacing the keyboard board is relatively inexpensive and straightforward, finding a compatible screen can be quite challenging. Moreover, proper installation is crucial to ensure its correct functioning with your laptop.
Choosing the right screen for your laptop
Failure to follow basic laptop operation guidelines can lead to display damage. This problem is often characterized by the formation of cracks that distort the image, as well as the appearance of graphical artifacts like spots, blurriness, white spots, “broken” pixels, rainbow-colored stains, and more. When faced with these signs, replacing the screen becomes a necessary solution.
The process of replacing the component typically takes anywhere from 20 to 60 minutes, depending on the laptop’s brand and specific features. The main challenge lies in finding a suitable replacement screen for the faulty one. It is recommended to purchase original screens that are specifically designed for your laptop model, ensuring maximum compatibility.
To obtain information about the screen model, you can refer to the technical documentation provided with your laptop or visit the manufacturer’s official website. Important information is also usually displayed on the back of the built-in monitor, but accessing it may require removing the upper cover.
Once you have identified the name of the laptop’s screen, you can start searching for it in specialized stores. These parts are available in service centers, online shops, and computer markets. If you cannot find an exact match, look for a compatible alternative considering the following characteristics:
- Type of screen (TN, IPS, PLS, MVA).
- Display diagonal (specified in the laptop’s technical specifications).
- Screen resolution (common options include 1366×768 and 1920×1080 pixels).
- Type of pixel backlighting (LED or CCFL).
- Coating type (glossy or matte).
- Placement of the connector (right or left).
- Software version.
Replacing the screen on your own
The process of replacing the screen is generally similar across most laptops. Begin by finding a suitable work area for the repair, gather a set of tools (such as thin screwdrivers, plastic spatula or guitar pick, tape, etc.), and carefully study the disassembly diagram specific to your laptop’s screen. You can find helpful guides on platforms like YouTube and thematic forums. Afterward, you can proceed with the screen replacement, following these three steps:
- Safely power off the laptop by disconnecting the power supply and removing the battery.
- Remove the faulty screen from its position.
- Install the new display in place of the damaged one.
Each step should be approached with care and attention to detail.
Powering Off
Disconnecting the laptop from the power supply is essential to prevent damage to critical components, such as the connector, graphics card, motherboard, etc., in the event of a potential short circuit. In laptops with a removable power supply, the battery can be easily removed. Simply slide the latch on the bottom of the case and take out the battery from its designated compartment. In some models, the compartment can be accessed through two fasteners.
If the battery is integrated and not easily removable, removing it will require more time and effort. To disconnect the integrated battery, you need to unscrew the back cover and disconnect the power cord. However, in certain models, the battery is accessed differently by removing the keyboard rather than the back panel.
In both cases, locating the power connector is relatively straightforward – just inspect the battery area. Usually, the connector is situated in one of the corners and is connected by thin wires.
Disassembling the damaged part
The disassembly procedure can be divided into two steps. First, you need to detach the outer frame near the display by releasing the latches and removing the screws. The fasteners are typically located along the perimeter of the cover or only in the lower part. In some laptop models, they may be covered by rubber plugs and remain unseen. By unscrewing the bolts from the frame, you can access the small latches that are positioned around the edges. Using a plastic tool, gently pry one of the edges and lift it until you hear a slight click. This will release all the fasteners.
Disassembling the screen matrix requires caution. This part, similar to the screen frame, is held in place by screws. Ensure that you unscrew all the screws securing the display. Usually, four fasteners are used by default, but some laptop variations may have metal brackets with eight screws.
Once you have confirmed that all the fasteners are removed, gently tilt the screen towards the keyboard and disconnect the ribbon cable on the backside, which is connected to the video card or motherboard.
Installing a New Display
The installation of a new display in place of the faulty one is carried out following the reverse procedure. To do this:
- Place the new screen in the position of the previously removed one.
- Connect the cable and secure it with a fresh piece of tape.
- Tighten the screws, first on the screen, and then on the outer frame.
- Insert the battery.
- Turn on the laptop to verify the functionality of the display module.
The last step can be slightly modified by first assessing the proper functioning of the screen. After mounting and securing the screen, as well as connecting the cable, insert the battery and power on the system. If the display shows a clear image and no defects or artifacts are present, you can proceed with the reassembly. Secure the outer frame of the display and tighten the bolts. Don’t forget to cover the outer bolts with plugs.
Conclusion
Service center employees and independent experts note that replacing the screen on Samsung laptops is relatively easy. This is attributed to the use of removable power supplies and the presence of only two fasteners on the frame, along with four bolts on the monitor. HP, Dell, Lenovo, Apple, and Asus laptops, on the other hand, have integrated batteries, which complicates the disassembly process.
Users are required to remove the back cover or keyboard.
MacBook Air notebooks from Apple have the most complex design. It is advisable to entrust the screen replacement on Apple devices to professionals. Additionally, the price of components for Apple products is quite high, and the average consumer is unlikely to want to risk attempting to replace the screen themselves.
In general, replacing a laptop’s display is a comprehensible and not overly difficult process. With a little patience, care, and attentiveness, you can change the fragile component yourself, avoiding unnecessary time and money expenditures. It is crucial to select the appropriate components and familiarize oneself with the specific disassembly details of the device.
