Q: I bought an external DVD drive, because the notebook is only a USB interface, read DVD discs sometimes say that power can not read the disc, there is an interface and the previous radio direct charge power adjustable 3 to 12 volts, I do not know it?

Q: My laptop external display watertight unplug the power adapter is gone But the notebook can not always use the battery is right I see you on the Internet that is there is a full-featured changes within the 3C option but I can not find the Please help me look very grateful.: If the original adapter is already aging, the filter is not good, for one. I feel you this is not the problem of ccc, because ccc can only control the video card, if it is caused by the graphics card, nothing more than the following situations: 1. Vertical synchronization, but you have a watermark, certainly not this, then only Is the display refresh rate, the general LCD 50hz, 59hz, 60hz, 75hz, in the desktop properties can be adjusted, generally adjusted to 50hz or 60hz, if it is 75hz, then there will be some watermark display. Ccc Lane can also be transferred, the desktop is more convenient, do not know what you are the system, it is difficult to say Anyway, these frequencies, 50,59,60 try, should be able to solve, if there is, it is likely that your power adapter to die, but now the analysis of what should be the refresh rate of the problem

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

Q: My computer is bought at the end of May this year, the power adapter has been no problem. But the day before yesterday in the speed of the sudden sound of crackling, like static, careful one, there is the friction of the pointer rotation. Probably intermittently lasted five minutes, and later returned to normal. But in the second boot, after about an hour this situation appeared, also continued for a few minutes before the shutdown did not appear. I checked it, which is related to capacitance, voltage, frequency. Also, when this sound is found, my power adapter is not plugged into the plug, and my battery is removed, is this also a relationship? I would like to listen to professional analysis, do not and I said to the repair station, if so I asked what? I just want to know about the specific circumstances, if not much impact, or can solve their own, do not have to repair. Thank you: 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 power adapter, the original 19v 3.95A can be replaced by 19V 3.42A it?: No problem, I and my students interoperability, we are ASUS, X42J model, his voltage is 19v 3.95A two I was 4.47, with the basic nothing, that is, the charging time can be normal Finished, the time to extend it.

Q: Haier brand of laptop power adapter can be universal?: Haier brand notebook power adapter is only common in the same series, rather than the whole Haier brand common. If you can not find the same type of adapter, you can choose the same parameters or different adapter adapter. The main parameters of the laptop power supply are: 1, the input power supply voltage and frequency, as long as the product is available in the mainland can, do not buy Hong Kong version or other local version. Usually 220 volts 50 Hz frequency. 2, the output voltage and current must be the same, or easy to burn the computer hardware. 3, the output power, can be equal to or slightly larger than the original output power. But must not be smaller than the original, otherwise the computer is easy to use when the fever is serious, no help to crash or restart some failure.
