Repair laptop power supply: Is it real?
The laptop has become an integral part of almost everymodern 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, think about its repair. Like any technique, it is prone to break down, a lot of electronics, bending, retractable and fragile parts make it vulnerable to mechanical damage. And the power supply unit turns almost into an expendable material. Repairing high-precision electronics in the home is risky, but the power supply, if you have the skills to work with a soldering iron, you can try to fix it.
Repair laptop power supply from anythe manufacturer begins with a fault diagnosis. As a rule, the first out of order is the connector. Try to move it to the sides, if the charge is lost, it appears, it's in it.
Then it is necessary to try to determine how it is possiblemore precisely the place of possible damage to the cable. Then disconnect the power supply from the mains and carefully cut the wire in the place of damage, securely connect the ends of the wires, disassemble 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, with the plug-in-the-daddy, everything is in order,it is necessary to check the counter 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 power connector can help.
Carefully dismantling the block, you can see,whereby the connector is connected to the board. It can be a soldering, maybe a plug. And here on the situation. It is necessary to carefully remove the old connector, without 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 laptop power supply can become more complicated,because some manufacturers fill the entire 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, while real.
If the laptop power supply is not repairedIt is limited to replacement of connectors, it is better to address to experts. Even if you have the skills to work with electronics, the notebook power supply circuit is quite specific, and finding its graphic appearance can be a problem.
When starting disassembly, remember, on the power supplythere may be voltage, which can lead to electric shock. In addition, there is a large number of small and fragile spare parts.
