Repair laptop power supply: Is it real?

The laptop has become an integral part of almost every modern family. The compact size, availability of all necessary functions and availability of work in any place made him the leader in sales of computer equipment. But not too often, when you buy a laptop, you think about its repair. Like any technique, it is prone to break down, a lot of electronics, bent, retractable and fragile parts make it vulnerable to mechanical damage. A power supply unit turns into almost consumable material. Repairing high-precision electronics at home is a risky business, but a power supply, if you have the skills to work with a soldering iron, you can try to fix it.


Repair of the laptop power supply from any manufacturer begins with the diagnosis of breakage. As a rule, the connector is the first to fail. Try to move it to the sides, if the charge is lost, it appears, it's in it.

Then you need to try to determine as accurately as possible the location of the probable damage to the cable. Then disconnect the power supply from the mains and carefully cut the wire at the fault site, securely connect the ends of the wires, propel and insulate. It is very important here not to confuse the wires in places, be sure to pay attention to the color. In this case, if the fault location is too close to the connector, shorten the cable and solder the new connector.

If, however, everything is in order with the "dad" plug, it is necessary to check the mating part of the connector, carefully consider the mechanical damage and the bending angle of the contact plates. If deviations are detected, an attempt to align them and put them in place, as a rule, does not lead to the desired result, only the replacement of the laptop's power connector can help.

Carefully dismantling the unit, you can see whereby the connector is connected to the board. It can be soldering, maybe a plug. And here on the situation. It is necessary to carefully remove the old connector, while not overheating the track or neighboring parts, then use a match to free the holes from the tin and also gently solder the new connector. If it's a plug, then it's easier to disconnect it and release the connector from the mount on the board (as a rule, these are latches). If the connector on the glue, when disconnecting from the board, take extreme care, there is a possibility of damage to the tracks. After that, the place of the old connector is mounted a new one - everything is extremely simple.

Repair of the laptop power supply can become more complicated, as some manufacturers fill the board with silicone. In this case, you will have to try. To release the connector from the dried silicone is a painstaking and very delicate process, at the same time real.

If the repair of the laptop power supply is not limited to replacing the connectors, it is better to contact the specialists. Even if you have the skills to work with electronics, the notebook power supply circuitry is quite specific, and finding its graphic appearance can be a problem.

When starting disassembly, remember, there may be voltage on the power supply, which can lead to electric shock. In addition, there is a large number of small and fragile spare parts. A wrong repair of the laptop power supply can lead to its damage and the failure of expensive items!
