Q:Notebook can not be turned on after connecting the power adapter
According to your situation it is estimated that this is a notebook self-protection procedures, put the battery bar Also, do not think that removing the battery battery will be more durable, exactly the opposite The battery installed, so that it will not damage the battery to a greater extent, Put the notebook on the bed, legs lead to high battery temperature, is the culprit Is not a problem, pay attention to the use of methods
Q:The laptop will automatically turn off the power adapter when the workload is large
Power adapter self-protection, more than power range automatically power off,
Q:Toshiba laptop power adapter original and non-original how to identify?
and notebook instructions will tell that several Power adapter can be applied, that several with a concept of the original, now fake too real, it is recommended not to buy.
Q:Laptop power adapter must match?
This may be used to ruin the hardware, it is recommended that you quickly switch back to the 90w adapter.
Q:What is the use of the bag on the notebook power line?
The power adapter is used to convert the mains voltage of 220 volts to a low voltage used by the computer, and to convert AC power to direct current and to stabilize the voltage.
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:Is the laptop plugged in with a power adapter?
Plug the power supply is plug in the power adapter ah, with the power adapter when the battery did not take down, the notebook is now designed to charge the battery directly to stop charging, so do not worry about the battery will be filled with bad, and if the battery is full of still External power supply, then the external power supply is a direct jump to the battery power supply to the computer, so do not worry about the battery, and finally talk about the better way to save the battery is usually on the computer on the computer, about a month with a battery, and then use To less than 10% of the battery power, and then filled with an external power supply, once every month, the longest battery life
Q:HP notebook warranty includes power adapter
HP warranty machine for one year, the motherboard two years, a year does not include power
Q:Lenovo laptop power adapter warranty how long
The adapter is the same as the main parts, the warranty for 2 years. Generally based on the invoice time warranty, no invoice based on the appearance date, the machine has the back
Q:Laptop power adapter squeak how to do
If there is no power supply instability, or the sound of the big situation is generally a normal situation, because the power adapter in the conversion of the power supply is bound to issue a fixed frequency of the sound, different frequency of the inductance coil due to its rated power Is not the same, so the size of the induced current sound is not the same, you can ask if the customer can replace. But if you do not cause other problems theoretically can refuse to replace. Some problems with the power adapter: First, the general power of the nominal voltage, is the open circuit output voltage, that is, outside the load is not connected, there is no current output voltage, it can be understood that this voltage is the upper limit of the power output voltage. For the internal use of the active power regulator components, even if the mains voltage fluctuations, the output is also a constant value, as the market generally small transformers, such as portable with the type of power supply, if the electricity fluctuations, The output of the power supply will fluctuate.
