MP3 can't connect to the computer, don't panic, teach you to solve

There are many reasons why MP3 can't be connected to the computer. I have contacted a lot of MP3s. I can roughly summarize the solution: 1. After the computer sets up MP3, it will pop up in the lower right corner and the computer is trying to connect to this USB device. Information, sometimes pop-up dialog box for the user to choose, some users have not seen it, no point, or because of some initial settings of the computer, some functions of the USB are prohibited. Solution: Right click on "My Computer", select "Attributes", "--" <;Hardware”--&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&" . Then plug in the MP3 again, or if you don't connect, right click on “My Computer”, “--&" Properties”--&&&&&&&&&&&&&&&&&&&&&&&&&&&&&" Serial Bus Controller & rdquo;, right click, then & ldquo; scan to detect hardware changes & rdquo;. 2. Driver problems MP3 CDs will often be equipped with “ 98 drivers & rdquo;, "upgrade tools", in the system above 2000, although theoretically do not need to install can also be linked to MP3, but often after installation, can let Online becomes smoother. So try to install these tools, if there is no “98 driver", then install the "upgrade tool" (some MP3 drivers are integrated in the upgrade tool). 3. The voltage problem of MP3 itself Because the trend of MP3 is to reduce costs by all means, so companies continue to adopt new programs, new masters, new FLASH chips, not to say that these new things are cut corners. The problem is that these new things are often Long-term debugging is required to achieve the best, but the market conditions can only allow the MP3 factory test to be put into operation on an interface of the computer, so there is often a phenomenon of not being connected or falling. In this case, the user needs to try several times, and plug in different USB interfaces, and then separately provide a good quality USB cable (usually the thicker the better, the copper is better than the iron), and then ensure that the MP3 power supply is normal (with charging) The device is full of electricity and try again). 4. After not using for a long time, it will not be online. Some MP3s cannot be connected or even charged after long-term use. Mainly because the MP3 is not powered off, it will not cause excessive discharge for a long time, and it will not reach the startup voltage. The solution is to repeatedly pull/plug the USB port and turn the power switch on/off (ON/OFF button, if not, press the PLAY button repeatedly). For example, after plugging in the USB interface, turn ON/OFF for 2 minutes, then turn ON/OFF for 2 minutes, then unplug and re-plug, then charge for 2 minutes. The purpose of this is to let MP3 charge a small amount of electricity to reach the starting voltage. 5. If these methods still do not solve the problem, it is basically certain that there is a problem with MP3 itself. At this time, it should be repaired or returned in time to avoid missing the warranty period. Strongly opposed to users disassemble their own machines, MP3 types are more than mobile phones, and often require the original program to re-upgrade, so most of the dismantling of the machine itself can not enjoy free services. It is also not recommended that customers upgrade their MP3s themselves.
