What if the computer version can't connect to the mobile phone?

1. What if my Android phone can't connect to the computer?

Methods/steps

First, the mobile phone u *** can't connect to the computer because the mobile phone doesn't have a driver installed. You can download pea pods and other software to install drivers.

Second, the solution that the second mobile phone u *** can't connect to the computer doesn't need to install anything. After you connect your mobile phone to the computer, click the box "Settings-Application-Development-Debugging u ***", and the mobile phone will be prompted "Turn on the function of U * * *", and click OK.

Third, download MicrosoftActiveSync_setup_4.0 or above from the Microsoft website, and then you can synchronize your computer. You can use the mass storage in the settings as a USB flash drive to connect your computer.

Install Microsoft's synchronization software MicrosoftActiveSync4.5. Generally, some softwares related to connecting mobile phones need to be connected with this synchronization software. If you just look at the data in mass storage, you can connect the computer directly with the data cable, then set the mode of mobile phone, connection and USB connection, and select mass storage to complete it.

Fourth, the mobile phone u *** can't connect to the computer because the power supply of the mobile phone u *** interface is insufficient.

Mobile phone u *** interface power supply is insufficient. You can charge the battery before connecting the computer, but it is too inconvenient. Let the power supply of the USB interface of the mobile phone be not less than the power consumption at the moment when the mobile phone is connected to the computer, so that the USB interface will be "fully charged" at this moment. How? Of course, I can't change the power supply of USB interface, so I want to change the power consumption of mobile phone. My specific way is to close all processes, close the screen of the mobile phone, and then connect the computer, in short, reduce the power consumption of the mobile phone. There is no guarantee that every friend will succeed in this method, but at least my starting point is good, that is, I hope to bring help to friends who have problems in this area.

5. The reason why the mobile phone u *** can't connect to the computer may also be caused by the system or its own driver. You can repair it in the following ways (try another interface or go to another computer for testing).

1. Press F8 to enter safe mode, and then exit. Select restart or shutdown to start, and then you can enter normal mode (repair the registry).

2. If the fault still exists, please use the system that comes with the system to recover until you don't have this fault (if the normal mode recovery fails, please press F8 to enter the safe mode and use the system recovery).

3. If the fault remains, use the system disk to repair it, open the command prompt and enter SFC/SCANNOW(SFC and/) to insert it into the original system disk repair system, and the system will automatically compare and repair it.

4. If the fault still exists, set the optical drive as the first boot device in the BIOS, insert the system installation disk, and press the R key to select "Repair Installation".

5. If the fault still exists, it is recommended to reinstall the operating system.

2. What if the mobile phone can't connect to the computer?

First, the data cable of the mobile phone is connected to the computer. What if the mobile phone prompts "the host is unresponsive"?

Reason: This is because you are using the USB interface line connected from the computer or the USB interface on the front of the chassis. Try the USB port on the back of the chassis.

Second, the mobile phone is connected to the computer. When "data storage" is selected, the phone will prompt "Another program is in use".

Reason: This is because your mobile phone uses a memory card or a theme in * * *, and the solution is of course to put the theme in the memory of your mobile phone. Do you want to use the theme of mobile phone C disk?

Third, the A disk of mobile phone can't be read by MMMB.

Reason: First of all, the smallest mistake is that you didn't install the PC suite, because MMMB needs the driver in the PC to connect to the mobile phone; Secondly, because you didn't choose the right connection formula for the data line in MMMB; Then you didn't install the registry; The last possibility is that the C disk of the mobile phone appears, not the A disk. In this case, you can reconnect the phone, use the USB interface on the back of the main chassis, and then turn on MMMB.

Fourth, the mobile phone can't connect to the PC suite.

Reason: Many Internet cafes can't connect to PC suite. First of all, because the firewall is driven, just turn it off (because it is edited by mobile phone, we will teach you how to turn off the firewall driven by the Internet cafe when using the computer). Again, because you use the front or USB connection of the computer host, you need to try using the USB interface at the back of the chassis.

Five, about the inability to install brush software such as JAF or Phoenix.

Reason: First of all, computers may not support these softwares, and some computer platforms cannot be installed. Secondly, shut down or uninstall all anti-virus software, continuous monitoring, firewalls, etc. For example, the monitoring function of 360 will be automatically recognized as Trojan horse and deleted when you download JAF!

Sixth, after the mobile phone is connected to the computer, there is no prompt to install the driver, and there is no new hardware prompt for the computer hardware.

Reason: 1. First, you need to insert the memory card into the phone and format it. Step: Setup-Initial Setup-Format additional storage devices (this option will not appear without inserting a memory card).

2. When connecting W388 and computer with data cable, the phone will prompt: "Connect the phone in memory mode?" Select Yes, the computer will recognize the mobile phone as a storage device, and the screen of the mobile phone will display "The function of the mobile phone cannot be used normally in memory mode".

3. There will be mobile storage in the computer, just copy the file directly.

Note: The memory card needs to have enough available capacity.

Why can't the mobile phone connect to the computer? Only the charging status is displayed.

1. Mobile phone data line interface failure;

2. Mobile phone motherboard failure;

3. Software failures (such as no driver, lost driver files) can be recovered by restoring factory settings, hard grid, and brushing.

4. Do not choose the data transmission mode (some mobile phones need to choose whether to connect with the computer when inserting the data cable);

5. The mobile phone can't connect to the computer (see some poor quality cottage phones).

You didn't describe the brand, model and detailed usage of the mobile phone in detail, so you can't imagine any problems. After confirming that it is not due to settings, weak connection, etc., please go to the mobile phone repair point to check.

3. The mobile phone USB is connected to the computer, but it can't. What should I do?

First of all, look at what mobile phone you are using. If it is an old-fashioned non-smart phone, it is generally necessary to connect the phone to the computer and install a PC package driver on the computer to use it. You usually need to buy the CD-ROM drive that comes with your mobile phone to use it.

If the mobile phone is a smart phone, the most likely reason is that the data cable of the mobile phone does not respond to the computer:

1. The data line of the mobile phone is broken. After the data cable of the mobile phone is connected to the computer, there is nothing wrong with the mobile phone. It may be that the data line of the mobile phone is broken (this situation is generally rare, unless the data line of the mobile phone is flooded or broken. )

2, the computer USB interface problem. If the computer USB interface is not available. It is very common that the USB interface of a computer is not used, which is generally caused by the following reasons:

1) The USB connector on the front of the chassis is not available. Some desktop computers have USB ports on the front and back of the chassis, but the USB port on the front of the chassis needs to be connected to the motherboard. If the USB cable on the front chassis is not plugged into the motherboard during installation, the USB interface on the front of the computer chassis will not be available, so if this happens, you can try to connect the data cable to the USB interface on the back of the desktop computer chassis (the USB interface on the back comes directly from the motherboard, so there will be no problem at all).

2) The USB interface behind the chassis is shielded. It is also possible that the USB interface in BIOS settings is blocked, which is generally used in Internet cafes. This is mostly the case if there is no response when the mobile phone data cable is connected to the computer in the Internet cafe. You can consult an Internet cafe attendant.

Inspection method: check whether it is a USB interface problem, or use a USB flash drive or mouse to test whether the interface is useful.

After the data cable of the mobile phone is connected to the computer, the mobile phone shows that it is charging.

1. USB setting problem of mobile phone. If the phone interface shows charging after the data cable is connected to the computer, then this has ruled out the problems of the computer USB interface and the phone data cable. This situation is generally a driver or mobile phone setting problem. First, we need to check the settings of mobile phones, especially Android phones. You need to turn on "USB debugging mode" in the phone settings before the computer can recognize it. So the first step is to check whether the USB debugging mode in the phone settings is turned on.

Open the settings inside the phone and find the USB debugging mode (enable debugging mode after connecting USB), followed by a tick. Check it to open USB debugging mode.

After the USB debugging mode is turned on, if the computer still cannot recognize the mobile phone, please install any auxiliary tools such as pea pods, Zhuo Dashi or 360 mobile assistant in the computer. When you open the tool in a networked state, you will usually detect the mobile phone and then automatically install the driver of the corresponding mobile phone. For iPhone, please download 9 1 mobile assistant or iTunes tool.

2. USB interface problem of mobile phone. The probability of problems with the USB interface of the mobile phone is very small, and this situation will be repaired at the after-sales point.

Generally speaking, there are two main reasons why the data cable of smart phone doesn't respond to the computer now. Of course, there are some very small possibilities, such as a problem with the mobile phone and a damaged USB data interface. , but this situation is rare. Generally speaking, there are not many reasons why the data line of mobile phone does not respond to the computer. Mainly pay attention to troubleshooting.

Solution: Find after-sales service!

There are three reasons why the phone can't connect to the computer:

software fault

Solution: After the mobile phone is connected to the computer, there is no prompt to install the driver, and there is no new hardware prompt for the computer hardware. Then we can try to restore by returning to factory settings, formatting, and brushing;

Four reasons why a mobile phone can't connect to a computer:

No data transmission mode is selected.

Solution: See if you need to choose to connect with the computer when the mobile phone is plugged into the data cable.
