subject: Different brands of notebook power adapter output voltage and current values are differences [print this page] Different brands of notebook power adapter output voltage and current values are differences
Since the internal laptop power adapter is a work in high voltage, high current state of the switching power supply, relatively heavy workloads, and is fully enclosed structure, the shell does not have cooling holes, and no fan to aid internal cooling, thus notebook power adapter at work, the internal temperature is high. Especially in the hot summer, touching the surface can feel the hot, the internal temperature is even higher. Thus in the daily office, entertainment, make it proper care and maintenance.

1. To create a good environment cooling
In high temperature environment, using a laptop computer, power adapter should be placed in direct sunlight and well ventilated place; not the power adapter on the laptop near the heat vent, heat or power adapter only distribution does not go out, but also absorb some heat. In the hot summer, we can put the adapter side to increase the contact area of the adapter and the air, allowing the adapter to better distribute the heat out. For better heat dissipation, we can pad between the adapter and the desktop into a narrow piece of metal or plastic pieces to increase the speed of air flow around the adapter to speed up the adapter heat distribution.
2. An exception should be promptly discontinued
Work in the power adapter Loud noise or smoke, is often damaged or malfunction, should immediately stop using, the professional engineer by the repair before it can again put into use.
3. A reasonable charge
When the notebook computer battery is charging, it is best not to run large-scale 3d games and other heavy work load that whole process, so that the output power due to the power adapter is not enough spare capacity caused by slow or rechargeable battery dissatisfaction overloading the power adapter and so on.
4. Different models of notebook power adapter can not be mixed
Different brands of notebook computer power adapter output voltage and current values so there are some differences, and therefore can not be mixed. Otherwise, at worst cause the battery to charge less power, the screen flashes and other phenomena, will be re-burned laptop motherboard or other hardware. Different models of the same brand of notebook power adapter for use should also be careful, it is recommended to consult a professional engineer after the operation
