Notebook manual service

While some laptops are upgradeable and repairable, desktop computers provide a simpler experience because parts are widely available and interchangeable. You can usually identify the manufacturer of a laptop by looking for their logo on the outside of the laptop, either on the back of the display, below the display, or on the bottom of the device. The name of the specific model is usually printed on the bottom of the laptop directly on the case or on an attached sticker.

For an explanation on what each part of the computer does, you can see the section below titled "How a Laptop Works. Sometimes the laptop is totally dead. Follow the steps below for some troubleshooting ideas. This page from Laptop Repair has more tips. If none of these steps work, you might need to replace the motherboard or take it to a repair shop that can work on the issue with the motherboard.

If the laptop has a separate power input board that is attached to the motherboard with a cable, you could try replacing that part first. Usually they are stuck fully white, black, red, green, or blue. Use this dead-pixel checker webpage to find a stuck pixel. This WikiHow guide provides some useful strategies for fixing a dead pixel, including flashing static on the screen via the JScreenFix website or applying slight pressure or heat to the stuck pixel area.

If none of these fixes work, you can replace your display with some guides here on iFixit. If this reaches about degrees Celsius, the computer will automatically shut off to protect itself. The processor might be very hot if the heatsink or fan attached to it are clogged with dust.

The best fix is to open up the computer and blow some compressed air into the fan to kick up the dust that builds up over years of use. You might need a new battery. See the replacement guides here on iFixit or elsewhere on the web for instructions on removing the battery in your laptop.

Alternately, you might just be running intensive software on your laptop like a game, video editing suite, or a simulation program. These apps will eat through your battery like a teenager after a fast. You can check the current maximum capacity of your battery vs. If you already know the ins-and-outs of computer tech, you can skip this section, but for the rest of the people out there this information might be helpful for the troubleshooting and repair tips shown in the section above.

Much of this information is explained further on HowStuffWorks. The screen consists of an array of pixels which can each change their color individually.

The resolution of the screen is measured as the number of pixels across the width and height of the display e. With some exceptions , the pixels in a display do not emit any light; instead, they change the color of light emitted by a backlight that sits behind the pixels. If either of these parts fails, they need to be exchanged in full. It executes all the code that comprises the programs you use everyday. The CPU generates heat which needs to be dissipated somehow—otherwise the computer overheats and shuts down.

While the CPU works as the brain of the laptop, the motherboard is the nervous system. The motherboard is the thin board that takes up most of the space in the computer and is generally the largest component. It is made from fiberglass with tiny copper lines embedded in it that criss-cross the surface. While some thick, older laptops have a socket for the CPU which allows it to be replaced, the two parts are often soldered together and cannot be replaced individually.

RAM components are either soldered directly to the motherboard this makes repairers sad or inserted into a slot on the motherboard this makes repairers happy. In the second scenario, you can replace RAM that has gone bad or add more RAM to your computer; RAM soldered to the motherboard cannot be easily repaired except by a professional.

Your programs and documents are stored on a hard drive or SSD inside the laptop. Since hard drives literally consist of platters spinning at high-speed inside your laptop, they can eventually die or break with a sharp impact shoutout to my resilient hard drive which survived being dropped down a flight of stairs.

Some SSDs, however, are soldered directly to the motherboard not again!? The battery provides power to the laptop when it is not plugged into the wall.

The battery supplies this extra energy as the product of a chemical reaction that happens inside. Over time, this reaction produces unintended by-products and the battery wears out. Thus, the battery is fundamentally a consumable part and will need to be replaced after a certain amount of time.
