Q:Does the laptop power supply have an impact on the computer?
Certainly influential, cpu, motherboard, hard drive and so on. Overheating will burn the motherboard.
Q:Laptop does not install the battery to use, only the power adapter to use, the computer itself is good or bad
it is good! I have been with the battery, 2 years, and now the battery can only be used for 15 minutes no electricity, so that without batteries to protect the battery, but is afraid of a sudden power failure damage to the hard disk
Q:My ASUS notebook adapter can use Lenovo adapter Mody
Temporary use for a while no problem, the power supply current are automatically within the scope of the acceptable. Of course, in order to ensure long-term use of stability and service life, or with the original power adapter is better.
Q:Laptop power charging interface is not appropriate, with a laptop power adapter adapter?
3, interface matching. Power interface to the same, the DC interface requires positive and negative interface is right.
Q:Can the HP Power Adapter be used on Lenovo?
Hello, thank you for choosing HP products. Different brands and models of notebook power adapter specifications (voltage and current, etc.) and the interface size is different, it is unpredictable whether it can be universal. In addition, the brand power adapter is supporting the use of this machine, if used in other brands of computers, it is prone to compatibility issues, it is likely to cause damage to the hardware, it is recommended that you do not mix.
Q:Why laptop power adapter do so big can not make mobile phone so small?
Because the notebook circuit complex and sophisticated, variable brain pressure device to prevent the circuit burned
Q:Buy a new laptop power adapter input current than the original large, can be used? Other are the same
This can be used. In the case of other parameters (rated output voltage, plug type, polarity, etc.) are the same, the rated current power adapter can replace the rated current of the small power adapter, but the rated current power adapter can not replace the rated current Power Adapter.
Q:Laptop power adapter squeak how to do
First of all, to know is that the power supply to the books and the battery power supply to the notebook is different. Battery-powered, the battery output is pure DC, very clean, the battery voltage is neither possible nor need to design a high, lithium battery chemical properties determine a cell output voltage can only be about 3.6V, so Many batteries are used in three cascade way, 10.8V also became a very popular battery voltage. Some batteries are slightly larger than the integer value of 3.6V, such as 3.7V or 11.2V, etc., in fact, to protect the battery. Power supply, the situation is more complex, first of all need to add voltage to further regulation filter to ensure that the power performance is not very good in the case of stable work, the voltage regulator after the two parts of the city, all the way to the work of the power supply , The other way to the battery charge to the part of the power supply to the battery when the same power supply, and the part of the battery charge through the battery charge control circuit can be added to the battery, the control circuit can be very complex, so the power The voltage must be greater than the cell voltage to have sufficient capacity to supply the charge control circuit to the units. Finally the voltage actually added to the cell will never be the nominal voltage of your power supply. Rest assured. Hope that the above information is useful to you
Q:Laptop power adapter how to deal with heat
Fever is normal, if the heating temperature is constant is normal. Notebook power adapter is actually equivalent to the desktop power box, the desktop has a fan, so it is not very hot, but with a long time blowing the wind or hot, the notebook depends on the shell heat, so the fever is normal, And the summer will be more hot, as long as the normal power supply like, as long as the hand can touch like. Different notebooks power adapter heat is different, each company invested in R & D costs different, I know the Lenovo book adapter is very hot, so I generally put it on the ground (adapter to the computer side Power line is longer). If you do not worry, you can put it on the fan, the kind of USB-style fashion!
Q:Laptop connected to the power adapter, always a power will not power. Install the battery does not turn on the power adapter can be normal boot.
This thing you use the multimeter unrealistic, the interface loose, poor battery contact, the motherboard failure is possible, you'd better get the computer city so that the master like a face experiment to show you, I most hope that the adapter has a problem, The
