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. Some manufacturers glue down their batteries which do you see a trend?

This chapter focuses on the boot process and Intel standard timing. In the repair of the laptop, in most cases, Timing applied on the power-on part in the system boot, so also called Power Sequence.
So literally, timing is time and sequence. The motherboard from standby to power-on, and then to CPU work, we feel just a short time.
And the motherboard made so much action; it will strictly obey an established order, that is to say, in the process of these steps, if the first step isn't completed.
Then the next step is not start. And there is a strict time requirement between each step, some will be accurate to a few milliseconds, for example, PWRGD Signal generation requires that each voltage stabilize about 5ms will be sent. It can be said that if you master the timing, then you have a basic idea of maintenance for all kinds of faults of the laptop. Hard starting process in general. The boot process of the laptop with Intel chipset below series 4 is as follows: a Without any electrical equipment supply power no battery and no power , through 3V button battery to produce VCCRTC to supply RTC circuit of the South bridge, to keep the operation of the internal time and save the CMOS information.
The clock signal distribution of above HM65 chipset The clock signal distribution of above HM65 chipset is shown in figure , the characteristic is that it must be 25MHz crystal when the bridge integrates the clock chip. This chapter introduces three kinds of Compal protective isolation circuit. Then explain one of the Compal standby circuit. Notebooks are complicated things, but laptop repair isn't as hard as the guys down the repair shop would have you believe.
Interestingly enough these service manuals e-books are the same ones that are being used by repair technicians.
They refer to these same manufacturer service ebook manuals when they are repairing your notebook for you. Do you need to upgrade a hard disk drive, memory or CPU of your laptop or notebook? Free laptop service manuals and user guides will help you find what you need. Service manuals show you step by step instructions for replacing components, photos for jobs that are specific to a particular make of machine. Looking for laptop tips and hints, free manuals links, find help troubleshooting, step by step guides, fixes for different makes of machines and piles of good laptop repair info!
