On the laptop power adapter problem

On the laptop power adapter problem

Answer:

Notebook power adapter matching the principle of the principle is: the input voltage to meet the requirements of the domestic exchange is 220V; output voltage and the original with the same output current must be greater than or equal to the original adapter output current, your future output current is less than the original will appear Power from time to time unexpected shutdown caused by increased data loss, the battery charge is not easy to rush to cause the battery aging process, the other adapter long-term work will increase the heat caused by increased safety risks.
Can be simply calculated; 19 * 4.74 = 90.06 90W 19 * 3.42 = 64.98 65W Obviously, the second is a virtual standard, can not be used It is not enough power, ranging from the adapter burned, while the motherboard is like other notebook hardware damage, unpredictable. The adapter is likely to burn after the high and low voltage to the notebook board burned the situation more common. My notebook is dell original 4.62A, when playing the game are very hot.
Notebook power on the two specifications, one is 65W, one is 40W, 65W power supply is a discrete graphics notebook, 40W is integrated graphics notebook. Just connected to the use of power, then there is no problem. Just if you laptop battery with the light of the words, plug in the power can not be the same as with the 65W, immediately you can use the boot. Because the current is low, the charging speed is relatively slow. The other will not have any effect
