Replacing a video chip on a laptop: instruction, price

Often, replacing a video chip on a laptop becomesnecessity. This part is also called a video processor or a graphics processor. The video chip displays the image through the multiplexer on the matrix (display) of the laptop. It is the main component of the PC, regardless of whether the built-in video chip or discrete. If there are problems with displaying information on the screen, the video chip probably needs to be replaced.

What is it

Replacing the video chip on a laptop is a necessaryprocedure if this part is out of order. The video chip is responsible for displaying the picture on the display and on the external monitor through special connectors. It all depends on the model of the laptop. The video chip is located on the motherboard and is considered the most hardworking component. He experiences great loads, performing many different actions. The peculiarity is that the video chip emits a lot of heat and quickly overheats. The graphics processor (GPU) performs the necessary calculations, processes the digital data, and displays the image on the matrix. Over time, active work leads to the destruction of the element (it can heat up to one hundred degrees) and requires a full replacement of the video card on the laptop.

Signs of breakage

Replacing a video chip on a laptop is required in thatIf working on a laptop becomes more difficult. There are basic signs of chip failure, which are recommended to pay attention to the user:

• On the screen appeared bands: vertical, horizontal, color, black or white.
• The flickering of the display started, poor sharpness, distortion of the picture, noise, blur.
• The appearance of a blue screen, a laptop crash, a self-reset.
• After turning on the laptop there is no picture or periodically disappears.
• If the laptop is on an uneven surface, the image may be lost.
• There are difficulties with installing and configuring the video adapter.

Causes

Replacing the video chip on a laptop is a complex process that should be entrusted to professionals. There are a number of reasons why the chip requires replacement:

• Factory brace or damage to the element during assembly.
• Ingestion of liquid. This causes oxidation and short circuit.
• Voltage drops, broken power to the chip.
• Overheat.The most common reason why graphics chips need replacing. Untimely prevention leads to the fact that the video chip is warming up. In the notebook, the fan and the radiator, which remove heat from the video processor, may become dirty with time and become covered with dust, and the thermal paste will dry. All this leads to the destruction of the chip due to insufficient cooling. Perform a preventive cleaning of the laptop should be once a year.

How to replace yourself

If the video card in the laptop is aa separate device and installed on a separate board, you can try to replace it yourself, which is not so simple. In this case, it is in a special standard connector, which is designated MXM (II or III). The video card also has a cooling system. It will be necessary to parse the laptop and remove the component with a screwdriver. The video card must fit the laptop.

All video cards are divided into two types:video chips integrated into the motherboard, and video cards on the MXM slot. In the first case, it is almost impossible to expose the video chip to repair, it needs to be replaced with a new one. Trust the process better to the professional, especially if there is no experience. The video card on the slot is installed on the same principle as in conventional computers. In this case, you can replace a failed chip or make a full replacement of the video card, use NVIDIA or ATI models. If you want to make a quality replacement, contact the service center. Do not forget that when you replace it yourself, it's important to choose the right video card for the laptop model, to install it correctly. If the video card is not selected correctly, there will be no image.

• In order to dismantle the video card, you must first remove the cooling system, unscrew the screws and remove the power connector.
• Next, unscrew the eight screws above the video card and processor.
• When removing the cooling system, be careful: it is important not to damage the chip.
• Clean the radiator plate from dust.
• Remove the old thermal grease.
• Apply a thin new thin layer on the chip.
• Collect the removed elements in the reverse order.

In any case, if the computer crashes, you must correct all the problems in time. The best solution is timely prevention of possible problems.

Price

If the device "brakes", overheats, emitsstrong noise, turns itself off, you need to replace the video card on the laptop. The price, which is requested by the master, on average is three thousand rubles. Remember: a new chip can not cost less than two thousand. If this is the case, it's likely that the component installed is supported. Replacement of the "game" chip will cost more. In general, get ready for the fact that for the whole work will have to pay about six thousand rubles.
