The system case is an important component of the entire computer. It is in the case that the “production workshop” of the entire computer is located, so to speak. It is in the case that the motherboard is installed, and the RAM, video card, processor and all kinds of wires and cables are already “hung” on it. Moreover, the power supply is located in a separate place inside the case, as well as the hard drive and drive.

Modern cases look quite attractive, menacing, aggressive, unusual... The developers have enough imagination, which means that ordinary buyers can choose from a huge assortment. But not only do the current buildings have an attractive appearance, they also have “working” advantages. Such advantages are the USB connectors, as well as microphone and headphone connectors on the front of the case, which in turn means that we don’t need to crawl under the table and get to the back panel of the case every time we need to connect a flash drive. I think everyone will agree that these are, in principle, trifles, but still, it’s more pleasant to just insert a flash drive in front and start working.

But, unfortunately, there are cases when some parts of the computer case fail. We are talking about the notorious POWER button, which is available on absolutely every case. Over the course of long-term use, this button may simply fail, for example, stop pressing or, on the contrary, sink deep into the case, and no matter how hard you try, you won’t be able to turn on the computer. What to do in such situations? If you don’t really need a computer, then it’s better to call a repairman and wait with peace of mind until he repairs everything, paying him a certain amount of money for it.

If you need to use the computer quite urgently, then perhaps you should use the following advice.

First, you need to find a flat surface and carefully place the system unit so that the left cover is facing you, while you should not disconnect all the wires in order to complete everything faster, but you should make sure that these wires are not strained. In addition, a prerequisite must be that the computer is disconnected from the power supply, as they say, you never know. Next, what needs to be done is to remove the left housing cover. In modern cases, this usually does not require any great effort, so this should not be a problem.

After removing the cover, a stunning picture will appear in front of you. You will see everything that at one time you paid a round sum for, and that usually works peacefully, making an innocent noise, and that which now does not want to “start up”. Our attention should be primarily focused on the multi-colored wires that run from the front of the case to the motherboard. There can be a lot of such wiring, and it’s not surprising, because there are also connected POWER buttons And RESET button, and USB ports, along with audio outputs. So, at the next step, we may need a little knowledge of English, which many received at school, because on the wiring themselves, as well as on the motherboard, near the connection of these wiring, it should be written what they mean. For example, you can take USB ports. On the motherboard itself, near the connection, there should be an inscription USB1, USB2, etc. This means that the wires connected to these connectors are nothing more than USB connection ports.

But we shouldn’t forget about our problem, and this means that we need to look for POWER postings(usually these are two wires woven together). Typically, the connectors to which the power or reset buttons are connected are located on the lower right side of the motherboard:

On most motherboards, these connectors are the same and consist of 9 pins arranged in two rows. The last two pins in a short row of 4 plugs are responsible for turning the computer on/off.

Here are connector diagrams for the most popular motherboard manufacturers.

MSI

AsRock

Asus

Biostar

Epox

Foxconn

Gigabyte

Intel

Once these two wires have been found, you should find where they are connected to the motherboard. Once the connection location has been discovered, it is worth carefully disconnecting these wires so that the small plugs are exposed.

That's it, now we're almost done. The final step is to turn on the computer; for this we need an ordinary stationery pen, preferably one that writes boldly. Once you have found such a pen, you can connect your computer to the power supply, and then carefully run the tip of the rod over these exposed needles. Or in other words, you just need to close these contacts. After these steps, the computer should come to life and the download will begin. If nothing happens, then you should repeat the procedure, but close these needles quickly enough.

Thanks to these simple steps, you can start the computer without any problems, but this should not be neglected, and it is better to quickly repair the start button on the case to avoid unnecessary problems.

Attention: Neither the author of this article nor the administration of this site bears any responsibility for possible problems that may arise when turning on the computer in this way. You will perform all of the above actions at your own peril and risk, and will be solely responsible for possible problems that are not described in this article.

Instructions

In cars that do not have ignition switches, the engines are started with a key or a button, but in such cars a chip or key with an electronic mechanism is needed that deprives the vehicle of mobility (English immobilizer - “immobilizer”). This device is found in cars: BMW X3, BMW X5, BMW X6, Mercedes C-Class, etc. If the ignition button fails, you will need to contact the company center to replace it, where you can also find out the prices for this type of work. If you try to do the same operation as with the lock, the engine may not start (on certain models, for example, Audi Q7, Volvo-XC70, BMW-7 series (E-65), etc.).

Sometimes you have to try hard to start the engine in frosty weather. The winter season sometimes becomes a real test for both the car and the driver.

The main reason for difficulty starting the engine is usually an insufficiently charged battery. But sometimes other reasons arise, which can easily be attributed to low-quality oils and fuel. Unfortunately, such factors are discovered too late. And precisely at those moments when you urgently need to go somewhere.

You will need

• Ether.

Instructions

It is necessary to prepare for the morning start of the engine in the winter season in the evening of the previous day. When parking, and especially in an open type, before turning off, press the accelerator pedal and increase the speed to three to four thousand for a few seconds, then sharply turn the key in the lock to position “0”.

In the morning, when you arrive at the parking lot, do not rush to start it right away. Before starting the engine, turn on the headlights for a few minutes. This action will warm up the electrolyte in the battery, which will make it easier to start the engine.

After turning off the headlights, insert and turn the key in the ignition, wait until the fuel pump automatically turns off, and only then try to start the engine by holding the starter key for 20 seconds. If the car does not start on the first try, then you need to take a minute break and then try again to start the engine. To successfully start a car in the morning in frosty weather, as a rule, no more than three attempts are required.

Almost every person has lost their car keys at least once in their life. And most likely it happened that a second set of keys was not at hand, but it was necessary to get into the car and start it. For those who want to know how to deal with such situations, there are some simple tips.

You will need

• Screwdriver

Instructions

Unscrew the screws and remove the panel by lifting it up. Now you can see the ignition key.

Remove the fasteners that connect the ignition key and steering column. This will unlock the steering wheel.

Unscrew the screws holding the electrical part (the part with the wiring) and the mechanical part of the ignition key together.

Insert the screwdriver into the key hole and turn it in the same direction as you would turn the key. This will start the car.

Unfortunately, this happens. We got into the car and discovered that the ignition key was lost. Or another unpleasant option - the key broke in the lock. How to start a car without a key?

You will need

• screwdriver, tester.

Instructions

Determine grounding. Usually this is a black or green wire. To check, connect the wire through the tester to the car body. The instrument needle is in the zero position. Therefore, this is “earth”. Once identified, it is advisable to insulate the end of this wire, since accidental connection to the power wires may damage the vehicle's wiring.

Identify the power wire(s). Most often it is a thick wire of yellow or red color. Sometimes there are several power wires. In this case, you need to find them all. Determining the power wires comes down to determining the voltage relative to ground. Using a tester, connect each wire one by one to ground or to the vehicle body. The arrow of the device will show the battery voltage value. Tie the found wires together. Avoid accidental contact with ground or vehicle body.

Identify the wires that supply power to the starter. Place the vehicle's handbrake in neutral. Connect the remaining wires to the power wires one by one. When one of the wires is shorted, the starter will start working. The required wire has been found. The remaining wires provide power to the vehicle.

We connect the power wires to the wire that supplies voltage to the car. Make sure that the connection is strong, as when the car is moving, the wires may become disconnected, causing the engine to stall.

We connect the wire that supplies voltage to the starter to the connection. Let's close. The car starts - we disconnect the wire and isolate it.

note

Under no circumstances should the power wires be connected directly to ground or the vehicle body! The car wiring will burn out. Do not allow power wires to come into prolonged contact with the wires supplying power to the starter.

Situations in which it becomes necessary to start a car without a key are not so rare in the life of an ordinary motorist. After all, both the key itself and the ignition switch break. To cope with a breakdown, you need to know the general principles of operation of car components.

The skill of starting a power supply without a computer and motherboard can be useful not only to system administrators, but also to ordinary users. When problems arise with your PC, it is important to check the functionality of its individual parts. Any person can cope with this task. How to turn on the power supply?

How to turn on the power supply without a computer (without a motherboard)

Previously, there were power supplies (abbreviated as PSU) of the AT standard, which were launched directly. With modern ATX devices, such a trick will not work. To do this, you will need a small wire or a regular paper clip to close the contacts on the plug.

On the left is a 24-pin plug, on the right is an older 20-pin plug

Modern computers use the ATX standard. There are two types of connectors for it. The first, older one, has 20 contacts on the plug, the second - 24. To start the power supply, you need to know which contacts to close. Most often this is the green PS_ON pin and the black ground pin.

Note! In some “Chinese” versions of the power supply, the wire colors are mixed up, so it is better to familiarize yourself with the contact diagram (pinout) before starting work.

Step-by-step instruction

So, when you have become familiar with the wiring diagram, you can start starting.

If the power supply is in the system unit, disconnect all wires and remove it.

Carefully remove the power supply from the system unit

Old 20-pin power supplies are very sensitive and should never be run without load. To do this, you need to connect an unnecessary (but working) hard drive, a cooler, or just a garland. The main thing is that the power supply does not run idle, otherwise its service life will be greatly reduced.

Connect something to the power supply to create a load, for example, a hard drive

Take a close look at the pin diagram and compare it to your plug. You need to close PS_ON and COM. Since there are several of them, choose the ones that are most convenient for you.

Carefully compare the pin layout on your plug and on the diagram

Make a jumper. This could be a short wire with bare ends or a paper clip.

Make a jumper

Close the selected contacts.

We have all seen more than once how in dashing action films the main character starts a car without a key by connecting a couple of wires. Of course, it is possible that a similar situation can happen in life, and it is not necessary to steal a car or participate in a chase. The ignition key may simply be lost or broken during a sudden jerk in the socket. Repairs have their time, but for now you need to somehow start the car without a key. So how to do this? We're not action heroes, so we don't need to rush. Step by step turning on the ignition of a car without a key looks something like this for all car models:

1. First, you need to carefully get your hands on the wires, which will require removing the protective cover from under the steering wheel.
2. Once this operation is completed, you will see a set of multi-colored wires leading to the ignition switch. You need to separate the wires from the lock in any way that is most convenient for you.
3. Having done this, determine whether each wire belongs to the vehicle’s on-board system and what each of them is responsible for.
4. First thing Let's calculate the ground wire. Its most common color is green or black. Some cars have this yellow wire with a thin green stripe. To make sure that it is the grounding wire in front of you, connect it through the tester to the machine body. A digital indicator at value 0 means that this is the same wire. Insulate its end to prevent an accidental short circuit with the power wires: this can lead to failure of the on-board system.
5. Now you need to calculate the power wire. To do this, study the colors - most likely it will be red or yellow, a lot depends on the voltage. It happens that there is only one such wire, sometimes there are several. Then you need to find everything. You will have to examine all the wires by connecting one multimeter probe to the ground wire or car body. You need to set the tester in advance to the voltage measurement position. Have you found all the wires from which the power comes? Also isolate them by grouping them first. Their accidental contact with the ground or machine body is dangerous.
6. Now you need to find the wire that powers the starter. Be sure to lower the handbrake and, in turn, connect the wires of unclear purpose to the power wire, or to all of them at the same time, grouped together. One will definitely turn on the starter. Mark it with something, a marker or tape.
7. Now connect the power wires to the wire that supplies voltage to the car. It is important that the connection is strong, otherwise the engine may stall at any moment.
8. Now let's do it like in the movies- we strike the wire that powers the starter, which will cause a short circuit and the car, if all the conditions described above are met correctly, will start. Once this happens, move the wire away.

How to start VAZ 2106, VAZ 2109, VAZ 2110 and VAZ 2112 without a key

In the case of a car VAZ 2106 You need to remove the ignition cover and find the brown, blue and red wires. The thick red wire is positive. The brown and blue wires need to be secured with electrical tape, and the red wires should be struck on both wires. The car should start. A similar procedure can be done for the VAZ 2109.

To start a VAZ 2110 or 2112 car without a key, you will need to pull out the entire headlight switch so that it dangles on the wires and remove the cover: there will be four connectors. Now you need to insert it differently - into three connectors so that there is one free on the right. At the same time, the fuel pump will start working and the ignition will turn on. Now open the hood. It is necessary to force the starter to start, for which it is enough to bridge the copper bolts, which are located in the back cover of the starter solenoid relay, with a wrench or scissors. The car started.

Activate all emobilizers and do not leave the car unattended in this condition!

You can clearly see how to not only start, but also open a “ten” or “two” without a key in the following video:

Now you know how to start a car without a key. Of course, a considerable number of cars of foreign expensive brands are already equipped with factory buttons and special key fobs; you can often find code panels for entering a PIN code. As for domestic cars, such an easy opportunity to start a car without a key should be alarming - do not leave the car unattended and without an alarm.
