The laptop power adapters is the source of the work force, which is a top-quality switching power supply, its work Principles is similar to color TV and other appliances in the switching power supply, make an important role in providing a stable notebook Low-voltage direct current.

Universal ac to dc power adapter are fully sealed small volume set Dollars, so the internal temperature is high, especially in hot summer day, touch the power adapter will work in a hot feeling. Because of this, the power adapter failure Rate relative to other components of notebook computers is still relatively high. In fact, many of damage and power adapter not serious, a little knowledge of the user to understand some of the circuit can try to repair.

Disassemble notebook power adapter device the upper and lower cover for the injection or packaged together with a strong adhesive, and without any He screws, so the general can only use violence to crack. However, as long as the right way, dismantling the power after the appropriate Adapter completely restored to their original, not carefully observed there is almost no open at the scene.

Step1: Connect the power adapter is placed in the horizontal side White paper, AC adapter with the electric knife blade along the power adapter cut the gap between the upper and lower lid, then tap with a hammer electric Work knife blade, the electric knife cut from the adapter into between the upper and lower lid.

The above method on the adapter The gap between the lower cover many different locations, then use the electric knife tip along the gap between the upper and lower lid a few paddling Circle, when the upper and lower parts of the first crack of a cover, put the tip in-depth, then slowly up and down the adapter separately Cover.

Step2: the power adapter open the shell, you can see the adapter circuit wrapped in a copper-screen Shield layer, with art knife to open the shield on the paper tape, and then open electric soldering iron shield and the internal circuit board with Then the two joints , you can remove the shield.

The power adapter has such widely used in our daily life, and buy one in high quality will be the best way and great way to avoid destroy. If you also want one too, you can visit https://www.smarts-electronics.com/ to find one that suit you most.
