19V 4.74A 5.5*2.5mm Power Adapter For Toshiba
- Three taboos for using power adapters:1. Never use an adapter with insufficient voltage or current. This is similar to the first no-no in battery packs, but from the point of view of the whole machine. Now the laptop configuration is getting higher and higher, the power consumption is also rising, especially the high frequency of the p4-m machine is a shocking power consumption, once the voltage and current of the power adapter is insufficient, easy to cause the screen flashing, hard disk failure, the battery can not be full and no reason to crash and other problems. If you're used to taking the battery off and plugging it in, you're more likely to cause damage (the battery ACTS as a buffer). The most important thing is that these problems do not appear immediately, but after a period of time to show, by the time the problem occurs, often have been back to the dead.
- In addition, when the current and voltage of the power adapter is insufficient, it may cause the line load to increase, the machine heating is larger than usual, adverse to the life of the laptop. For the sake of portability, the internal structure of the laptop power adapter is very compact, although not as fragile as the battery, but also to avoid collision and fall, the author himself once used a dropped power adapter, resulting in a trip at home, later found that the internal short circuit. As for the water flooded, because most of the power on the ground, often found after the water flooded, so should develop a good use habit, connected to the mains end and then plug in the laptop, and try not to put the power directly on the ground, but to put in their own can see the place. 3. Avoid bad heat dissipation. Many people attach great importance to the heat dissipation of laptop computers, but few people care about the power adapter. In fact, the power adapter on many machines generates as much heat as the laptop, so be careful not to cover it with clothes or newspapers, and keep it in a well-ventilated place.
