Q: I am Acer's notebook, now with 2 oh minutes or so, it has been very hot. Just bought a few days. Before the five hours are not now hot, how is it? It seems that I changed the original WIN machine into the XP system after the situation, I also use someone else's adapter, the adapter and I have the same model, the results are very hot, do not know how? Does the adapter heat up to the computer? Seek the solution: Notebook use a stage will be slightly hot or a little hot is a normal phenomenon, nothing and the adapter heat is also a normal phenomenon will not hurt the computer do not worry I use the Acer I5 460M spent more than a year feeling it Still very comfortable usually play WOW all right thing it's very good heat dissipation I just look at him this is what you buy what model ah

Q: Tsinghua Tongfang laptop power adapter lost, who knows the parameters, input voltage and output voltage?: Tsinghua Tongfang notebook power adapter Input voltage: 100V-240V (depending on model) Output voltage: 11.1V-19.5V (depending on model) Power: 60W-90W (depending on model)

Q: Boot time to paste up to listen to a little, shut down without being able to hear. Before not pay attention, yesterday only to find such a thing, this normal?: Notebook power adapter generally use the switch circuit, the output 12V DC power supply. 1, as the notebook DC / DC converter circuit power supply, in the switch circuit, the most prone to "creak" sound is the switch transformer coil (ringing), or high-voltage filter capacitor (fire); 2, it may be the power adapter has been thrown, may make high-voltage filter capacitor loose or desoldering, which issued a "creak" sound; 3, it is possible to switch the coil of the transformer shock, issued a sound.

Q: The original 65w bad, sometimes with less than 65w, can 90w it?: To check the current and voltage size, and the opening in the forward or negative

Q: Why laptop power adapter do so big can not make mobile phone so small?: Because the voltage of the notebook is very large

Q: 19V 3.42A notebook can use 20V 4.5A power adapter?: Yes, the high power problem is not big, low to die

Q: Laptop power adapter how to use a multimeter to test is good or bad: But the load capacity (plus the rated load after the voltage is still normal) can not be directly measured.

Q: As if the output are rated voltage rated current without affecting the use What is the principle of this? What circuit is used to achieve?: The current digital devices such as notebooks, mobile phones and other power supplies are used switching power supply, allowing a wide range of voltage input, that is, 90-240V voltage input, can be integrated through the high-frequency switching circuit rectifier, output such as DC 3V, 5V, 20V Equal voltage. This mode and before the transformer through the transformer after the rectifier output DC is not the same, the transformer mode is generally only ± 10% of the voltage range.

Q: There is a 19V, 4.74A, is not it a bit high?: 12V that can try, may output power is not enough, affecting performance. 19V that do not use the

Q: Power adapter problem: HP comes with the adapter will be a problem, after all, this is an electronic product, not one hundred percent. But the problem of these brands a little less.
