Notebook power adapter maintenance process and explanation is we should pay attention to,Christian Louboutin chaussures Vous vous le 70mmvente pas cher
The author only some small maintenance before the power adapter,Christian Louboutin chaussures Mago 160mmvente pas cher, such as radio and the walkman the ac adapter and no laptop adapter, so can maintenance experience of blind dates, walk the one step see step. Power adapter is general by shell, power transformers and of rectifier circuit. Should say, open power adapter shell is need to spend a kung fu. Notebook computer power adapter shell fusion a very tight, want to open at a draught is almost impossible. Open the enclosure to bounce back after, it should be said that is not possible. This can be as we identify whether the power adapter for original of a standard. In FIG. 3 already open a plastic caps. The metal screen layer role is self-evident. Look at the power adapter internal,Christian Louboutin chaussures Vous-vous Strass 85mmLivraison gratuite pour vous, in fact also nothing important mysterious, and ordinary switch, voltage circuit there have been no major difference, also is some capacitance, resistance,Christian Louboutin chaussures La Favorita 140mmvente au rabais, inductor,Christian Louboutin Lady Gres 160mm chaussuresLivraison gratuite pour vous, switch and diode power core chip . Of course, these are some high fever element. The notebook computer power adapter power in the W or so,Christian Louboutin chaussures Daffodile 160mmLivraison gratuite pour vous, internal heat generation of main through the plastic casing conduction send out. The surface temperature of the power adapter is quite high, adapter, that is a standard furnace, 80 ? estimate is little not. So, the author suggest that we use in the notebook computer, try not to pile up on the power adapter, especially something flammable material. Note pins, this is author took it after the operation results. Before the capacitance of the already have a little bulge (figure 6), under high temperature, electrolytic life is very brief, have the article says, every 10 ? temperature rise,Christian Louboutin chaussures Balota 150mmLivraison gratuite pour vous, electrolytic life span shorten half. As it is, the capacitor is not affected use,Christian Louboutin Bianca 140mm Amethyste chaussuresLivraison gratuite pour vous, but after all in there is time bomb, one day will burn out on the main board of the notebook computer power supply circuit. So the author found a capacity of the change to a little bigger. I craft is not too good, and there is no spot welding. So welding effect is poorer, but absolutely strong. The author did not find the adapter,see more, also didn find the circuit diagram,Christian Louboutin Très Mélanger chaussures 150mmvente au rabais, the IBM original adapter just search on the net to the Toshiba notebook computer power adapter circuit diagram. The author control circuit board to see once, it was very have similarities. In a reference to here. IC chips in power in the photo above reflect, slightly for IC chips too complex, the author also without the chip on the parameters, reason not to illustrate. But IC chip is absolutely power adapter is the most important in one of the electronic components.
