Power adapter for the host power supply and battery charging, 220V AC voltage can be reduced to the voltage suitable for notebook computers, in the process of converting the current due to electromagnetic phenomena emitted by the electromagnetic sound, and will send a certain amount of heat, Can not worry. If the electromagnetic sound of the power adapter suddenly becomes larger and the abnormal heat condition occurs, the power adapter should be unplugged immediately and the machine should be checked with the power adapter after turning off the machine.

Q: Recently bought HP's 4416s notebook, but when used to find the power adapter will issue a creak sound, looked at other people's notebooks seem to have no such obvious squeaky. Looked with their own model almost HP notebook, although there are creak of the sound, but it seems not my voice big. Someone explained that this is the current work when the sound or the town ...
It is the power supply is not pure and the capacitor capacitor reasons, such as the sound is too large, then there is a problem with the power adapter, does not affect the use, but the power adapter will soon be hot, and greatly affect the life of the adapter
Q: My notebook HP520 laptop power adapter that line bad contact how to do for a power adapter looks like some of your want to open to see their own line but did not find the screw off
With the knife on the back of the hook, along the gap crochet, see the cracks are exposed to metal color, with a flat screwdriver into the gap gently turn it open, which is three groups of silver-plated shield, One layer is the ground (black sets) the middle of a layer of output lines (white sets) a cluster is the input line (blue sets of welding line line feet)
Q: Books normal operation, a plug in the power adapter to shut down into the state of charge, and can no longer boot, but unplug the power, but also normal operation, why ah
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: In the past when the power adapter has a squeaky sound. Now plug in the power supply adapter will be squeaky. Power on a while to power, and power indicator light does not shine, power adapter silent. Put a while the power adapter connected to the power there will be squeaky. And can make the computer boot. Boot a power supply and no response. I wonder if the power cord is broken or the adapter is broken?
1, you can put the laptop power cord adapter to take out the line, replace and then connect the laptop, if the normal charge, then the power adapter is out of the cable, 2, the adapter out of the outlet line, with a multimeter test adapter power output pile, if there is voltage, the adapter intact, if the output pile without voltage, then the adapter is damaged.
Q: The laptop power adapter has been ringing, and the charging indicator flashes repeatedly. What's the matter?
On the laptop when charging, the power indicator flashes, but also charge into the power. From the problem, generally have the following: 1, may be the power adapter of the power connector, due to poor contact; or battery interface then Touch the wrong; can check the next. 2, may be caused by a battery failure. Lu master with the next test, the battery work Look at the current loss of the battery to determine whether the battery is damaged. 3, may be the motherboard power control, charge and discharge circuit is damaged due. If the master with Lu detection The battery is good, that is, the motherboard power supply and discharge circuit is damaged.
