What is the necessity of laptops in today's world? This question does appear to us when we see the predominance of laptops in our surrounding environment. Truly speaking, people of the modern world who do travel on a regular basis are in the need of a personalized computer that can be used at any time. The situation is such when business professionals, students pursuing business courses are finding themselves helpless, without their computers. Why? Since most of our information remains stored in the computers, we feel virtually helpless if it is not in order. This happens to be one of the main reasons why having a laptop is a necessity in today's modern world. Now may be you are a person who is not having a laptop computer yet. But even though you should know that one of the most imperative aspects of having a laptop computer is having a great power supply. Though the laptop computers can be run by a battery, but most often when we do work with the laptops, we do prefer to use the general power supply. If you are working on a daily basis there is a need for you to be economic. But have you ever thought if the DC Jack or Power Plug fails to function what will happen? Just remember such a situation when the Power Plug of your laptop is not operating and you are in doldrums! What shall happen then? Indeed, at that very hour there is the need of expert hand or mechnics to restore the power facility. It is in that situation when you will think of us.
What do we do? We are in this specific discipline for quite a number of years and with a profound experience. To be very precise, it is by the virtue of our efficiency and perseverance we have been able to gain the confidence of people at large and has been expanding our operation by leaps and bounds. What do we do in the normal condition? We do tackle any crisis or mechanical failure of the laptops and try our best to resume work at the earliest. Take for instance, the notion of power supply. Are you aware of the term DC power jack and their mode of operation? For your information, DC power jack in any DC appliance, especially in case of a laptop computer, happens to be a connector, which the power adapter gets connected to the device. It is a small part that does take quite a bit of stress from having the plug pushed in and pulled out at a variety of angles. Moreover, it will come loose from the motherboard of the laptop in the following time. Now, when it is found that the DC jack is broken or appears to be loose, the laptop will no longer receive any stable power connection for its best operation. It is the toughest situation for the user who is not aware of the fact what to do. He or she will find in due course of time that the very plug can be moved to and fro for the sake of getting or loosing power in certain directions. What's more, a broken or loose DC jack can cause further damage to the laptop motherboard due to the gradual creation of good amount of heat by the poor electrical connection on the board. The DC jack is soldered to the motherboard of most laptop computers. It has been found, that in many cases the DC jack can be resoldered to the motherboard, but most of the time the constant wiggling of the jack to get a good connection does create a huge damage in the inner side of the DC jack. In this respect, it is generally recommended by most of the repair professionals or us that a new fangled DC jack should be mounted on the laptop motherboard in the place of trying to simply resolder the old DC jack.
So, perhaps by now you have got the idea that the most common piece of hardware to fail on any laptop is the DC Jack or the plug that does accept the power on the laptop. There is no doubt in it, that there are several reasons for the high failure rate, but the two most prominent reasons are the poor handling and poor design. It is known or generally believed that 90% of these DC jacks are soldered right on to the motherboard. So are you confident to do the entire job on you own? If you can it is fine. After all it is your personal laptop, and you should know better than us!
But, however, if you can't then? What shall you do? Have you ever thought of that? Are you going o call any one standing at your doorstep or will you opt for the most proficient ones! Think twice before you dial the number. Why? Well it is up to you that your are going to call. But indeed there are several instances when the inexperienced and novice persons do destroy the entire infrastructure, making it perfect to be sold to the nearby blacksmith! Therefore it is best for you to call the inexperienced ones like us. Note it down, that repairing the DC jack on any laptop is indeed a major repair, and for that there is the requirement of qualified persons. This repair will require dismantling the whole notebook, and removing the motherboard. Once anyone has an access to the DC Jack it will be seen that the pins have got soldered to the motherboard. To the naked eye it might look like nothing is wrong with them, but a slight break in the solder will cause these problems. There shall be the need of a soldering iron and with a very fine tip. What is the necessity of the fine tip? The presence of fine tip is there for the sake of avoiding damage to adjacent components. There is also the need of a perfect application of the solder to each pin making sure the solder gets evenly spread. The solder should have a dull look to it when you are done. Now once all the pins have been soldered, there is a need to reassemble the notebook and also to test it. For ths sake of avoiding this samage in the future there is anee to take extra care, at the time of inserting and removing the external power cable.
Now if it is a LCD monitor, then the saga of troubleshooting the power supply happens to be easier. In general, it is small and compact and usually has only one output which happens to be of 12 volt and does range from 2 ampere to over 4 ampere. However, there are some designed ones which are of 18 and 24 volts. In thus day and age, most LCD power supplies are build into the main board such as the Dell E151FP LCD Monitor while the older type were separated as power pack module. It has been found through different types of operation, that the power pack module type is more easy to diagnose. Reason? One can replace another working unit just to make sure is the power pack that is rendering the greatst problem. Besides, there is the spossibility of the use of an external dc power supply to power up the LCD to confirm if the power pack is faulty. If there is no such availability of the external dc power supply, this very method can always be used by any indivdual for ths sake of isolating the problem, especially the symptoms whih are of no power, low power and power blink. Using the rear light bulb (12 volt) from a car and connect it to the power pack output jack. If it light brightly then the power pack is okay. If it blink or dim the power pack have problem. Why have to use this method to test it? Because, if there are components shorted or leaky at the LCD main board, it will affect the power supply performance.
There it is eminent that troubleshooting the LCD power supply is not that difficult. However, there is the necessity for any expert professional to know how a power supplies work. At several times it happen that the concerned individual is either unsure or not professionally adept regarding the knowledge of how to troubleshoot power supply. In that case it is necessary for that person to be confident enough by going through the regular discourses or by making himself literate by the numerous websites in the web world.
Lastly, the repairing of the DC power jack in laptops is something most laptop repair centers don't really want to do. In this respect we happen to be totally exceptional, as we love to take up challenges. It is indeed our specialty service where the most experienced technician, skilled in PC board soldering and desoldering is sent for the job of repairing.
