Q:How much time can I usually use a non-original laptop power adapter?: The general machine power supply is also about 80 ocean, non-professional staff is best not to save the money

Q:Do not copy from other places, to talk about their actual experience: I can tell you so that the battery is in order to sudden power failure when the hard disk will not be high-speed rotation of the case suddenly stopped to cause bad sectors, etc. can also protect the electronic components, although the battery solution adapter will be lost, but It's nothing compared to your important information

Is the problem of power or computer problems? Rush!: 1, with a multimeter to check whether the normal socket, the supply voltage is 220V. If the utility voltage is not normal, it is recommended to replace the use of environmental testing. 2, with a multimeter to check the power adapter output voltage and current is consistent with the label. If the gap is very large, and the mains voltage is normal, you can determine the power adapter failure, Need to replace the notebook power adapter. 3, if the above check is normal, remove the laptop battery, do not external adapter. Press and hold the notebook power button 5 seconds to repeat 3 times. After releasing the notebook residual charge, Insert the power adapter separately, power on the test. 4, if the fault remains the same, check the notebook's power interface, whether abnormal.

Q:My ASUS notebook power adapter is 19V ~ 4.75A can use other computer adapter 19V ~ 3.42A charger: Charging no problem, if you use the power supply is not necessarily able to bring up. In the case of the same rated voltage, you can use the current than the device needs a strong current supply, it is best not to use low current. The current on the power supply is the maximum current, inserted in the use of equipment, the device in the current chip will automatically reduce the flow of the current.

Q:Pro: my computer with no electricity on the use of a look, the power adapter light is not bright, do not know the triangle plug line is broken, or the power adapter is broken! Give a detailed solution! how much is it?: Take the next socket to try to know it. The new sixty-seven it There are cheap ones. Are generally triangular bar, the feet of the unqualified it How to do leakage Your power adapter behind a lot of English, see a few V on it. General 14-inch is 19V. My ASUS N43, with the 19V.

Q:After looking for a Dell, the input voltage is 19.5 I was the original HP output 18.5, a difference of 1V, can not mix?: Can be, but the burden on the motherboard will increase and hurt, you have seen who with the desktop rated 500W plus a 700W power explosion of the Mody; high-power, the current big no problem, but the voltage will increase the hardware life and stability Sexual damage, of course, there are fever, I used the Shenhua K580C standard 90W 19V power supply, and later because the video card power down enough to buy their own 120W 20V, the temperature simply can not suppress, and unstable, with the power index With the power supply is how much the best with the number of voltage, of course, notebooks are equipped with power consumption wall of such things, if you buy a high power power does not brush bios is not play

Q:Apple laptop power adapter bad how to do it: Third, in the test process, if the resistance pin is found in the solder, and then use the welding tool to repair it up, the power adapter and then installed, boot test, the results resolved. It should be noted that if the test process, encountered a capacitor in question, you can buy a model and capacity of the capacitor (the price of 5 yuan), and then the problem will be sold down the capacitor, the new capacitor welding up Can be. If you find a problem with the IC power chip, then the same way to solve, of course, because the IC chip is absolutely one of the most important electronic components of the power adapter, the capacitor is too complex.
