Laptop power adapter are fully sealed design of small size, and its power consumption is generally up to 35W ~ 90W, so the higher the internal temperature, feel the power adapter will be hot, especially in the hot summer, touching work. Because of this, the failure rate relative to the laptop power adapter other components is still relatively high. After the power adapter is damaged, buy a brand new a few hundred dollars to spend, go to the secondary market Amoy also need a hundred dollars. In fact, many power adapter damage is not serious, a little knowledge to understand some users can try to repair the circuit

Tools / materials

Steps / methods
1.1 Up and down the notebook power adapter cap for injection package or with a strong glue, and without any screws, so generally only with violence to crack. However, if done correctly, disassembled completely restored to their original power adapter, not carefully observed almost do not see open traces.

3.3 Then open the housing of the power adapter, you can see the outside of the adapter circuit package has a copper shield, using a knife to open art paper tape shielding layer, and then the two electric soldering iron welding shield and open internal circuit board connections point (see below), you can remove the shield.Asus AC adapter.

4.4 Also separated between the shield and the circuit board layer thick rigid plastic film (Figure 4), the then art knife open, you can see the board “true colors” of the
