ASUS laptop does not turn on, what should I do? Asus laptop repair - common reasons for contacting a service center The laptop does not show signs of life.

It is better to entrust professionals if you do not have experience in disassembling equipment. Turning to specialists will avoid aggravating the problem, since an inexperienced person with a screwdriver in his hands can do more harm than good - the plastic case of laptops is quite thin and breaks with a bang. Likewise, appeal to service center will allow you to get a working laptop the very next day, while a full range of work will be carried out - fault diagnosis and elimination.

Despite the warnings of manufacturers and a virtual ban on laptop disassembly and repair with my own hands, there is nothing difficult in this if you are ready to disassemble consistently and accurately. True, it must be remembered that in this case you risk losing the guarantee, since the glued seals will be damaged. If the warranty period of your laptop is already over, then you can try to disassemble it. Below we will look at common problems with Asus laptops.

Power connector problems

A common problem with some Asus models is the power connector. There are plenty of stories on the forums on the Internet about replacing several connectors at once, after the failure of the next one. What it is, a marriage with a component supplier or a constructive miscalculation, the Taiwanese company does not disclose. The problem is solved by disassembling the laptop and replacing the non-working connector.

There are also situations when the power cable is connected, the plug is inserted into the socket, but the charge either goes or does not go. When moving the wire, the power jumps again. This indicates a break in the wire, usually at its base at the bend. To solve the problem, we take:

• Soldering iron with solder and tin, as well as an oxidizing agent;
• Stationery knife;
• Insulating tape.

We cut a hole with a knife (you must be careful, as you can damage the working wires or break their insulation), separate the broken contact and the wire. Using a heated soldering iron, we connect the plug to the wire. Finally, we wrap the restored wire with electrical tape.

Hard drive replacement

The most common reason for contacting service centers is the need to replace hard drive. There can be many reasons for this. Here are the most common of them: the desire to increase the volume of the disk, replacing a damaged or non-working disk, recovery of lost information. hard replacement disk - the most simple operation with a laptop. To do this, turn off the laptop, remove the battery, unscrew a couple of bolts on the bottom and remove the cover. After removing the cover, you will see a view of the hard drive and RAM, which can be easily replaced by disconnecting the cable from the HDD and removing the RAM from the slots.

When assembling a laptop, you must follow the reverse sequence. Particular attention must be paid to the reliable connection of the cable. In a laptop, everything is similar to a regular PC, but if repairing a stationary computer is easy due to the large free space, then in laptops the components are placed very compactly. Difficulty can arise only when connecting wires, connectors, cables.

Variety of faults in laptops

In most cases, all components that are interchangeable with others are subject to repair. HDD replacement and SSD drives, RAM, Wi-Fi modules, keyboard, touchpad, screen matrix and so on is painless. The only difficulty that arises is the destruction of the laptop, in which you can break something. It will also be necessary to contact specialists in case of problems with motherboard and elements soldered into it (resistors, transistors, capacitors, etc.).

A detailed description of how to solve hardware problems with turning on a laptop, with image defects, as well as many other problems at home.

Introduction

This guide will talk about solving some hardware problems with a laptop, netbook or computer. This includes primarily problems with turning on the laptop, problems with the operation of the video card and display, as well as minor problems with the operation various devices like a drive, a hard drive, and others.

Warning: The solution to this kind of problems involves disassembling the device and directly interfering with its operation. If you do not have a sufficient level of knowledge and experience, then it is better to entrust this work to the specialists of the service center. At insufficient level knowledge and experience, you can get a "corpse", the repair of which in the future will not be economically feasible. Some of the actions that will be described in the article may void your right to warranty service. Again. We doubt our abilities - we give the laptop to specialists in the service center. That will be cheaper.

Very important note: before disassembling a laptop or other similar equipment without fail pull out the battery And turn off the power! Also, if possible, use ESD protection. The internal elements of the laptop are very sensitive to it and can easily fail.

So. Now you can move on to specific problems with the laptop and how to solve them.

Problems with turning on the laptop

Description of problems with turning on the laptop

The laptop does not start when the power button is pressed. It can be either a complete lack of reaction, or options when the laptop seems to turn on, the fan is running, but there is nothing on the screen. A separate point is the case when the laptop freezes during the POST when loading the BIOS and you cannot enter the same BIOS.

Causes of problems with turning on the laptop

First, consider the case when the laptop does not turn on at all and the case when the laptop turns on, but there is nothing on the screen.

In fact, there can be a great many reasons for such problems. Consider the most common:

1. Nutrition problems. This may be a failure in the operation of the power supply, failure of converters and voltage stabilizers on motherboard. Also, do not exclude cases when the contact in the power connector is simply broken or an internal damage to the power supply cable has occurred. Often, the absence of some kind of laptop reaction to the power button speaks precisely of power problems;
2. Chipset Issues. It's already more fun. Chipset, speaking plain language, this is one or two large chips on the motherboard. If there are two such chips, then one of them is called the north bridge (located closer to the processor) and the south bridge. Recently, their functions have been combined in one chip. Often, with problems with the chipset, the laptop still shows signs of life when you press the power button. The laptop seems to turn on, the indicators are on, but there is no image. Also, if there are problems with the south bridge, failures in the operation of USB ports, SATA ports and other interfaces may occur. If before the laptop stopped turning on USB did not work well, the hard drive with the drive occasionally disappeared, or there was some other similar problem, then it makes sense to say that the problem is in the south bridge;
3. Processor Defects. This rarely happens, but it also happens. Same symptoms. The laptop does not turn on;
4. Problems with the multicontroller. Multicontroller (in the common people, just a "cartoon" or Embedded Controller) is also pretty big chip. It usually includes a keyboard controller and other additional buttons (KBC), a power controller, fan control, an interrupt control controller, and other interesting things. If something happens to this microcircuit, then the laptop will also not want to turn on;
5. Problems with the video card. It's also a fairly common problem. If before the laptop did not want to turn on, you saw various image defects on the screen or the laptop did not want to work on the driver from the video chip manufacturer, then the problem is most likely in the video card.

If the laptop still turns on, the inscriptions are visible on the screen, and at the BIOS splash screen, it freezes, then there are also several options:

1. Problems with RAM;
2. Problems with hard drive or drive;
3. Problems with other system devices.

Solving problems with turning on a laptop

Here we come to the most interesting. Consider how you need to act if the laptop does not want to turn on and there is nothing on the screen. Here is an example algorithm:

1. It is necessary to check whether there is voltage at the output of the power supply, whether it corresponds to the passport (indicated on the power supply itself) and, most importantly, whether it sags heavily when connected to the load. At the last moment, I will stop in more detail. Often there is such a breakdown in power supplies: the idle voltage is normal, and if you connect a load in the form of a laptop, it sags a lot. It shouldn't be like that. To check if the voltage at the output of the power supply is not sagging much, you need to somehow hook a voltmeter to the output of the power supply when it is connected to the laptop. This can be done both with thin wires, and very carefully to the contacts of the power connector on the laptop board.

If there is no voltage at the output of the power supply or it sags heavily, then the problem with turning on the laptop is in the power supply. In this case, the power supply must be replaced or repaired. But if everything is fine with the power supply, then we read on.

2. Try turning on the laptop without the battery. If it suddenly turned on, then this means that the problem is most likely in the battery.

3. You should try restoring the BIOS. More about this is written in this manual: BIOS. Questions about firmware and BIOS recovery. We ask questions on the same forum.

4. Now it's time to deal with the chipset and video card. At home, you cannot change the chip or do reballing. This requires not only knowledge and experience, but also the corresponding rather expensive equipment and templates.

Fortunately, there is a way to temporarily revive a failed chip. This line can be very different: from days to years. This method consists in warming up the chipset and video card. It is worth dwelling on it in more detail.

Chip warm-up

For an unprepared user, this process may seem like something from the category of fantasy or at least "street magic" :) Actually this method very often helps to revive the chip. They are often used in service centers.

essence this method is that the defective chip heats up to 220-250 degrees for a short time. This leads to the fact that the junctions of the chip with the substrate and the substrate with the board are soldered and contact is restored.

In service centers, a specialized soldering station is used to warm up the chip, but what to do if one is not at home? Fortunately, there is a way out of this situation. You can use a conventional building hair dryer with a temperature controller:

Such a hair dryer is inexpensive, and a useful thing in the household. To warm up the chips, you need a hair dryer with an outlet air temperature controller. Power and nozzles are not critical.

Warning: warming up a laptop is a very dangerous and complicated operation. There is a risk of damage to laptop components from static electricity and excessive heat. It's also worth mentioning that not all laptop components handle heat well. Some of them (capacitors, for example) can even explode when heated. It is worth resorting to warming up only when the laptop is not working and, in general, there is nothing to lose.

Let's take a look at how it warms up. First you need to disassemble the laptop. I already gave recommendations on how to do this above. Find your chipset and graphics card. This is what the laptop motherboard looks like:

Yours is rather different. At the top right you can see the north bridge and the place for the video chip. To the left of the north bridge is the processor socket. At the bottom left near the battery is the south bridge. If you have any questions with the search for where you have which bridge and where the video card is, we turn here:. Be sure to attach a photo of your motherboard to the message.

In our example, we will warm up the northbridge:

and processor:

Before taking on a hair dryer, you need to take care of the thermal protection of the remaining components of the board. We don't want a jet of hot air to spoil the little white plastic connector for the processor, do we? For thermal protection, it is convenient to use aluminum foil. It is in every kitchen. It is used to bake something in the oven.

Important note: working with foil greatly increases the risk of damage to components by static electricity. This must be remembered. To protect against static electricity, use antistatic mats and wrist straps whenever possible.

Cut out a piece of foil and make a hole for the chip itself with the substrate. It will turn out something like this:

Now you can go directly to warming up. We set the temperature on the building hair dryer to about 220-250 degrees. It is very important. Put more - you will just burn the chip or it will just move on the board along with some other components. In this case, a trip to the service center is guaranteed to you. Put less - you may not get the desired result.

When everything is set, you can start heating. It takes a few minutes to warm up. This is how the process looks like:

And this is how the process of warming up the processor looks like:

After warming up the chip, give it a few minutes to cool down.

Important note: In addition to warming up with a hairdryer, there is another much more dangerous way. It consists in heating the chip in the oven. This method is suitable for single chips and for small boards like a video card. I think there is no need to explain why it is impossible to put a motherboard or others into the oven and what can come of it. Therefore, I advise you to refuse warming up in the oven. It is very dangerous.

Let's return to our algorithm. If the warming up of the video card, the north and south bridges did not work. The laptop does not start. What to do in this case?

In fact, the choice is quite small: either one of the bridges, a video card or something else burned out, or a multicontroller died, or a microcircuit with BIOS firmware very bad. In any case, you cannot solve this problem at home. It is worth contacting the service center. They will either try to fix it, or they won’t bother and order a new motherboard or video card. You can try to get them yourself and replace them. To do this, you need to contact either the service center, or go through online stores. It's hard to find stuff like this on the open market.

Let's now consider what to do if the laptop freezes on the BIOS splash screen:

1. We turn off all external devices like flash drives, memory cards, mice and others.

2. if it is possible to enter the BIOS, then go into it and disable the BIOS splash screen. In this case, the download process will be displayed on the screen and it will immediately become clear where the process stops.

3. if you can’t enter the BIOS, then you need to proceed by typing. First, remove one memory bar from the laptop. Turn on and check. If the laptop still freezes, then put the bar back and take out another one. If the laptop continues to freeze, then put another bar back and pull out the CD / DVD drive. We check. If it hangs further, then we take out the hard drive.

In this way, you can determine what the problem is. Usually problems arise due to poor contact in the connectors, due to errors in the RAM and on the hard drive. By the way, checking these devices for errors is shown in this manual:. If errors are found in the RAM, then it must be changed. Likewise with a hard drive.

Separately, I want to note the case when the laptop starts to freeze at the BIOS stage after the user tries to install various non-original Windows builds. During installation, the bootloader in the MBR is damaged and in some cases this can lead to a freeze. To fix this, you need to remove the hard drive, connect it to another computer and repartition it. More details here:. You can also boot from a disk with Windows XP, go to the recovery console by clicking on the letter R, and enter commands fixboot And fixmbr.

Now we can move on to other typical problems.

Solving problems with the image on the laptop monitor

Description and causes of image problems

Image problems are also quite common. They appear in the form of image defects, various bands on the screen and other things. Here are examples of what it looks like:

Defects can be very different. Sometimes even the image doubles or quadruples. Plenty of variations.

There are few reasons for this type of problem:

1. Problems with the video card;
2. Problems with the matrix cable;
3. Problems with the matrix itself.

Solving image problems

To solve problems with the image, you need to do the following:

1. Connect an external monitor to the laptop. If the same defects appear there as on the main display, then with a high degree of probability we can say that the video card is to blame for this. To solve this problem, you need to warm up the video chip. The warm-up procedure has already been described above. If it doesn't help, then you need to change the video card. If it is built into the motherboard, then you need to carry the laptop to a service center, and if not, then you can change it yourself. New video cards can be ordered at the service center or in online stores. For upgrade inquiries, please visit: . For problems with the video card here:.

If everything is fine on the external monitor, then most likely the problem is in the matrix or in the cable.

2. If the image on the display changes when you change the position of the cover with the matrix, then the problem is almost guaranteed in the cable. This is what the loop looks like:

The problem can be both in the cable itself, and in the places of its contact with the matrix and with the motherboard:

Often the reason is poor contact of the cable with the connectors. Less often, the train itself is frayed inside. In such cases, it is usually changed.

But if your image defects do not change when the lid moves, then go to the next step.

3. Problems with the matrix itself or with its decoder:

Typically, the repair of such breakdowns comes down to replacing the matrix.

Important note: all questions on video cards and matrices please state here:. I highly recommend you read the thread first.

Solving other hardware problems with a laptop

Laptop randomly shuts down or freezes by itself

There are entire guides for these problems: and.

If the cause of the shutdowns is not overheating, then it is worth updating laptop BIOS. If it does not help, then contact the service center.

Webcam, Bluetooth adapter and other devices periodically disappear

It is worth first of all to check the cable with which they are connected to the motherboard. You can also check how they behave in Linux:.

There is a separate manual for the inverted camera image: .

Wheezing, slowing down or jamming sound

Read first this manual and check how sound works in Linux - . If everything is fine in Linux, then the problem is with the drivers or with Windows itself. If Linux has a similar problem with sound, then we contact the service center.

That's all. You can state problems with turning on the laptop here:, problems with video cards and the image on the monitor are discussed in another topic:. Questions about disassembling a laptop and warming up chips should be stated here:. I strongly recommend that you read the topic before asking a question.

Hello dear subscribers! Your Asus laptop has worked for a couple of years and in certain moment stopped turning on? Or an unpleasant surprise happened immediately after the purchase? It is worth saying that the laptop may not turn on in different ways: in one case, we hear the sounds of the cooler, the indicators light up, but it does not appear on the screen Windows boot; in another, the computer does not respond at all to pressing the power key, as if it is completely discharged and disconnected from the network.

This material contains general information, there will be no specific instructions, but the article should help identify the defect and, if possible, eliminate it yourself without contacting qualified specialists.

ASUS laptop won't turn on! What to do and how to be?

Important! I do not recommend doing self-repair if you do not have experience in servicing computer equipment. When replacing and cleaning components on a desktop computer, I do without the help of a service center, but if you need a complex laptop repair, I recommend that you contact professionals. The most difficult stages of self-repair are the disassembly of the laptop and, accordingly, the diagnosis of the problem. There are no soldered parts left in modern models, so replacement is mostly simple.

Perhaps you will immediately find your situation in this article and will know what actions should be taken in the future. Sometimes the simple cleaning of laptop coolers from dust solves the problem. By the way, here is one of these articles, where I already told a similar example:

In other cases, repairs will be required. When diagnosing a laptop, you should take into account the period of its operation, it may be time to change the main components. Choose the appropriate section and proceed to a detailed explanation. So, perhaps, we will begin to consider the main and probable causes that will tell you why the asus laptop does not turn on.

1. The laptop does not start, but the indicators light up

If you hear the sound of coolers and see blinking indicators on the keyboard, then this is already a good sign. At least you can be sure that the power supply is working properly. There are a lot of reasons for this behavior, I want to describe the most common:

- BIOS crashed. Looking through computer forums, I was surprised that many owners of Asus laptops have the BIOS itself crashing. I have been a laptop owner for a long time, but I have never had such a problem. It is quite simple to determine that the cause of a faulty BIOS is quite simple: when you turn on the screen lights up, but the standard information about the computer is not displayed, you cannot enter the BIOS using hot keys.

Will help solve the problem BIOS reinstall. For example, I can even offer you one of these articles, where I already talked about BIOS:

Although the process is more complicated than flashing the operating system, you can cope with it without the help of a service center.

- Problems with the operating system. The BIOS boot was successful, you saw a screen with information about the laptop, but nothing progressed beyond that. The operating system loading image may freeze on the screen or an error message may appear. Nobody canceled the black screen of death either. If you don't know what I'm talking about, read here.

The solution here is quite simple - try repairing or reinstalling operating system Windows. Most likely, it is after this that you will be able to solve the problem due to which the asus laptop does not turn on.

- The display is broken. If the boot is in normal mode, the usual sounds of Windows are heard, but the screen remains black, then it's time to take the laptop for repair, since you won't be able to fix the screen yourself. If the display contacts have come off, then the defect will be fixed in 20 minutes, but if the screen burns out, you will have to change it. Do not even try to climb on your own, it will cost you more.

- Hardware failure. The computer may turn on without the participation of one or more components, but it will not fully work. For example, you will not be able to boot if the video card is burned out or RAM, so if the above options are not suitable, the Asus laptop should be carried for diagnostics.

The second image shows an example of a failed BIOS, sometimes no messages appear on the screen at all, this is also a signal that in basic system any problems have occurred. Blue screen hints that it's time to reinstall Windows. You can also try to boot into safe mode, if on system drive there are important data left that you want to save before reinstalling. Let's look at the second reason why the asus laptop does not turn on.

2. The laptop does not show signs of life

Important! If your laptop refuses to turn on without charging, but when connected to the network, all problems disappear, so you need to check the battery. Perhaps he's out of order. Until you buy a new one battery, the laptop can only be used from the network, like a regular PC.

In addition to the battery, the problem can lie in any component. South and north bridge, processor, hard disks, motherboards - all these components can burn out, as a result, the computer will stop turning on. It is also worth checking the external unit itself, since it is he who is responsible for supplying electricity to the rest of the hardware in the computer.

In any case, diagnostics will help determine the exact cause. If the laptop is still under warranty, I recommend contacting the official service center, where you should be provided free help. As for third-party services, it is worth choosing trusted people. Only a person with experience in working with electronic devices can perform a component check with their own hands. If you see that the computer does not turn on, you should stop trying to “reanimate” it and immediately contact the specialists. Well, we are moving on and it's time to consider the third reason why the asus laptop does not turn on at your home or at work, let's say so.

3. Asus laptop shuts down or restarts

This usually happens while running some cumbersome application (for example, a photo editor) or a demanding computer game. Before shutting down or rebooting, the laptop starts to make a lot of noise, and if you put your hand on the case, you will find that it has overheated. Reboot or shutdown occurs due to overheating of the laptop hardware.

For starters, it’s worth checking how things are inside the Asus laptop. The computer may need cleaning - you will be informed about this a large number of dust on the boards and on the blades of the coolers. It is also worth changing the thermal paste, which is located between the processor and the motherboard. According to the regulations, it must be changed every 6-12 months if you want the laptop to give maximum performance. There you are detailed instructions for laptop prevention:

Healthy! For laptops, special stands with additional airflow are provided, an example of one of which you can see in the photo below. This is a useful thing for those who use 100% laptop performance.

Sometimes the reason is a too demanding program that is not provided for your hardware. Before launching a game or other application, it is recommended that you familiarize yourself with its system requirements- This general rule for all computers. The system captures the excess of the permissible temperature and independently turns off or restarts the computer, thereby protecting the laptop components from burning.

So, completing today's article "Asus laptop does not turn on" so that you do not have to spend a lot of money on repairs, follow all the operating rules. Do not forget to clean the Asus laptop from dust, change the thermal paste regularly. These simple conditions will help your laptop work for the entire period declared by the manufacturer. In general, by and large, it should be noted that the information that is present in this material is relevant for all models of Asus laptops. Finally, I recommend that you read other articles on this model line!
