Q: Laptop power consumption is 117 watts but the power adapter is 90 watts what the situation?: Power adapter maximum output power of only 90W, then the machine's power consumption can not exceed this value, the hardware mark prevail, the software is not measured out of this, but according to the various models of hardware projections, for reference only Only, there is no practical significance.

Q: New to buy a notebook, with only two or three hours on the fever, the temperature is relatively high, how to deal with: 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: The original 65w bad, sometimes with less than 65w, can 90w it?: Output voltage uniform The socket size and polarity can be the same. To ibm the book, for example, t60, 61 with the 90w power supply, and x61 with 65w power supply in the output voltage, plug polarity is exactly the same, the difference is the output current is the power size. With 90w alternative 65w completely no problem. If the emergency, can also be used to replace the 90w 90w, but the first to turn off the battery is full, and then boot, so not the same time the battery and load the machine will not exceed 65w power load capacity. The internal power supply, the adapter for the power supply after the conversion and then supply cpu and other equipment, so the adapter to meet the power in the case of a slight deviation from the voltage are generally able to work, but in order to be stable and reliable, it is recommended to use the original adapter.

Q: ASUS Laptop Power Adapter 19V 4.74A. Use a multimeter to measure how much no load.: No load generally will not exceed 19.3v, measured.

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: My laptop's power adapter always has a sound what's going on?: Aging may have a current sound, or bad contact may have, look at is not bad contact

Q: I read, I changed the adapter will be able to charge the battery, and my adapter can also be charged to other models of the same type of notebook (dell N5110), but their own adapter is not able to charge their own notebook: One: The power adapter is faulty Power adapter has a lot of friends called the charger, although not accurate enough, but it is indeed very image. Judgment is not due to the power supply is not charging is also very simple, the replacement method can be. This failure in the DELL notebook repair more common, DELL notebook with LBK (DELL architecture), charging circuit design is more special, if the problem will not charge the adapter, if not the original adapter will not charge the problem. HP slightly new notebooks also have more models using this charging circuit, the more classic failure is HP NX6400 CPU occupancy rate is 100% due to power failure caused.

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: Two possible: First, the power adapter is broken, the other is the power interface is broken! Go to the customer service to check it, the general computer testing room free bar, find out what the problem, do the next step. good luck!

Q: Notebook access to the power adapter can not be powered, then the battery can be powered and normal use, (power adapter is not bad). Is this what is the problem, if the maintenance shop repair about how much money?: Two possible, one is the power adapter is broken, the other is the motherboard AC interface is broken, do not know what your notebook model, should be some of the computer's AC interface is integrated in the motherboard,

Q: HP laptop plug in the power adapter wireless fast speed, unplug the power supply speed slow how to solve?: It is possible to charge the line at the socket and the line at the line where there is a bad contact with the proposed maintenance.
