Repairs charger Laptops: From point soldering to complete block replacement

Need to B. Repair of laptop chargerThis is one of the most up-to-date reasons for the appeal to service centers. Our masters have a serious experience in solving problems of this kind.

Our service center performed repair of charger (power supplies) laptops. We correct any violations in the work of "Charging" of laptops. In most cases, either a wire or power adapter comes. The "Charger" laptop may suffer due to a variety of factors. Often, the voltage in the network changes dramatically, and such differences can damage the device. It happens that your pets, having tested with wires, overcoal them. Either the device is damaged from the closure inside the laptop. Also, over time, condensers located in the block can dry up. Try to contact the service center quickly, and repair the device, otherwise, the damaged device can damage the laptop itself and repair will cost much more expensive.

We can "cure" any breakdown that your charger has undergone.

What work to repair laptop charger performs our service center?

We bring a spoiled e-board into the working state, we turn the components of its elements.

The laptop has become an integral part of almost every modern family. Compact size, availability of all necessary functions and availability of work anywhere made it by the sales leader computer equipment. But not too often when you buy a laptop, think about it. Like any technique, it is characteristic of breaking, many electronics, bending, nominating and fragile parts make it vulnerable to mechanical damage. And the power supply turns into almost the consumable material. Repair the high-precision electronics at home - the case is risky, but the power supply, if there is a soldering iron, can be tried to fix it.

Repair of the power supply of the laptop from any manufacturer begins with the diagnosis of breakage. As a rule, the first in order comes out the connector. Try moving it to the sides if charging disappears, it appears, it is in it.

Then it is necessary to try to determine as much as possible the place of likely damage to the cable. Then disconnect the power supply from the network and gently cut the wire at the damage place, to reliably connect the ends of the wires, suck and exhibit. It is very important not to confuse the wires in some places, be sure to pay attention to the color. At the same time, if the place of damage is too close to the connector, shorten the cable and solder a new connector.

If, with a plug, "dad" everything is in order, you need to check the response part of the connector, carefully consider mechanical damage and the bend angle of contact plates. If you detect the attempt attempt to align them and put in place, as a rule, it does not lead to the desired result, only the laptop replacement can help.

Carefully disassembled block, you can see, whereby the connector is connected to the board. It can be a solder, can plug. And here in terms of the situation. It is necessary to carefully drop the old connector, while not overheating track or adjacent parts, then with the help of a match, freeing the holes from tin and also gently solder a new connector. If it is a plug, then it is easier to disconnect it and release the connector from fastening on the board (as a rule, it is a latch). If the connector on the glue, when disconnecting from the board, observe extreme caution, there is a chance of damage to the tracks. After that, a new one is mounted at the place of the old connector - everything is extremely simple.

The repair of the power supply of the laptop may become more complicated, as some manufacturers pour the entire board with silicone. In this case, have to try. Release the connector from dried silicone is a painstaking and very thin process, while real.

If the repair of the laptop power supply is not limited to the replacement of the connector, it is better to refer to the specialists. Even if you have the skills of working with electronics, the nutrition of the laptop is sufficiently specific, and it may be a challenge to find its graphic look.

Getting Started, remember, there may be a voltage on the power supply, which is able to lead to addition, there is a large number of small and fragile spare parts. And the wrong repair of the laptop power supply can lead to its damage and failure of expensive elements!

Buying a laptop or a netbook, or rather counting the budget for this concentration, we do not take into account further related costs. Laptop himself should say $ 500, but another bag is $ 20, a mouse is $ 10. The battery when replacing (and its warranty resource is only a couple of years) pulls $ 100, and the power supply will cost the same amount, in the case of its combustion.

It is about him and the conversation here. One is not a very wealthy acquaintance, the power supply has recently stopped working for laptop Acer.. For the new one will have to give almost a hundred dollars, so it will be quite logical to try to fix it with your own hands. The BP itself is a traditional black plastic box with an electronic pulsed converter inside, providing a voltage of 19V at a current 3a. This is the standard for most laptops and the only difference between them - the power plug :). Immediately give here several power supplies schemes - click to enlarge.

When the power supply is turned on to the network, nothing happens - the LED does not shine and the voltmeter shows zero. Verification of a network cord did not give anything. We disassemble the housing. Although it is easier to say than to do: screws or screws are not provided here, so we will break! To do this, you will need to put the knife and knock on it slightly hammer. See do not cease, but then destroy the fee!

After the housing is slightly disperse, insert a flat screwdriver into the resulting slot and carry out the contour of the compound of the body halves, carefully flushing it on the seam.

Disagreeing the body check the fee and parts on the subject of something black and charred.

The transversion of the input circuits of the network voltage 220V bulk revealed a malfunction - this is a self-healing fuse, which for some reason did not want to recover when overloading :)

We replace it with a similar one, either on a simple fusible with a current of 3 amps and check the work of BP. The green LED lit up, testifying to the presence of a voltage of 19V, but there is still nothing on the connector. More precisely, sometimes something accesses, as when the wire is inflection.

We have to repair and connect the power supply cord to the laptop. Most often, the cliff occurs at the injection site into the case or on the power connector.

Cut the first at the body - not lucky. Now near the plug, which is inserted into the laptop - there is no contact again!

Weight case - a break somewhere in the middle. The easiest option, cut the cord in half and leave the workshop, and knock out the non-working. So did.

Shipping back connectors and test. Everything has earned - the repair is completed.

It remains only to glue the halves of the housing by glue "moment" and give the power supply. All repair of BP took no more than an hour.

With relative simplicity, the power supply board still has a number of functional elements. Common out of condensers. They have a certain working resource and are quite sensitive to temperature drops.

Identify non-working capacitors will help visual inspection. But getting access to the "filling" of the charger problematic is problematic - their housing, as a rule, have an unintended design. Without proper skills at home carefully operate and reliably close the body is unlikely to succeed.

After capacitors, check the condition of the fuse. As a result of the voltage jump, he could overdo it by performing his own direct function. The serviceability of the fuse means the beginning of the procedure for detailed diagnostics of each node of the power supply unit to detect the problem element. Repair is reduced to the replacement of broken components and must be completed by testing work.

Prices for repair of a laptop charger

Power supply - an important element of a mobile computer. It makes it possible to connect to the network and charge the battery, thanks to which you can work offline, without connecting the laptop to the outlet. But it happens that the repair of a laptop charger is required. What reasons may be caused by faults?

When is required to repair a laptop charger?

If you have connected a mobile computer to the network, but it does not work, and the battery is not charging, the likelihood is that the problem is in the power supply. It also happens that when connected there is a contact, but it is intermittent, and the process of reserving the energy of energy in the battery is stopped, it continues again. This may indicate other faults, for example, a non-performing power connector. Therefore, the master uses a special tester to measure the voltage on contacts and accurately determine what happened to your laptop.

Because of what can fail the power supply? This can be caused by different reasons, among which:

mechanical damage caused by drops or blows;
damage cable from frequent bending or sharp jerks;
malfunction of wiring or outlet;
sharp jumps and voltage drops on the network;
moisture getting inside the power supply;
overheating - especially when used in an unheated room.

How do we carry out the repair of a laptop charger?

If the diagnostics showed that the problem is in the power supply, the wizard inspects it, if necessary, disassembles and determines the cause of the malfunction. As practice shows, it is often possible to repair charger for laptops inexpedient. And work, and components cost too expensive compared to the cost of a new power supply.
