Q:Does the laptop power adapter pull off the mark for a long time?
Short circuit. Power on, indicating that the power adapter is no problem. A computer lights off, indicating that the motherboard short circuit, that is, the motherboard on the short circuit protection phenomenon, the computer motherboard is broken, it is recommended to go after the sale for the motherboard, the warranty period this thing should not have money.
Q:Why is my laptop plugged in the power adapter to shut down the
Phenomenon analysis: the current motherboard on the CPU temperature monitoring function, once the CPU temperature is too high, more than the motherboard BIOS set the temperature, the motherboard will automatically cut off the power to protect the relevant hardware. On the other hand, power management and virus software in the system can also cause this phenomenon to occur.    Should be the policy: the sudden shutdown of the phenomenon if it has been to confirm the CPU cooling is normal. Open the chassis visual fan blade is working properly, and then enter the BIOS option to see the fan speed and CPU operating temperature. Found that the fan is the problem, the fan on the relevant dust maintenance or replacement of better quality fan. If you exclude the reasons for the hardware, enter the system, from the "kiss to death" installation CD-ROM installed in the installation of power management, and then completely killing the virus. When these factors are excluded, the cause of the failure may be the power of aging or damage, which can be confirmed by replacing the power law, the power is broken on a new, must not continue to use, will burn the hardware
Q:Laptop power adapter affect the power cat Internet, what method to solve?
Laptop power adapter affect the power cat Internet, what method to solve? Hello, not for the laptop adapter that should affect you online But the power cat can not go through the row You put the electric cat should be on the street without a switch and the lights on the socket The same power cat can not cross the air switch

It is estimated that the power adapter is not plugged plug plug caused by the connector is too loose, poor contact, resulting in large resistance, the sound is a normal response, with the laptop battery out of no relationship. It is recommended that the power adapter connection plug must be tightened, otherwise it will lead to excessive heat at the joint, dissolve the interface or lead to abnormal output voltage. Resulting in unnecessary losses.
Q:Laptop adapter why the computer power lights on the off?
Only electricity is good. Agree with such a design, there are electric lights on the lights, energy-saving lamps when the energy-saving environmental protection.
Q:ASUS notebook plugged in the charger did not respond
Either the problem of the charger is either the problem of the machine with the charger contacts
