Can start normally with battery, but cannot connect to PC

USB interface: dirty, poor contact with internal shrapnel;

Replaceable USB interface

Inside the USB cable (male): dirty, poor contact;

The PC CPU's query and access to the USB port stopped, and the USB driver was turned off (you can unplug the USB and reinsert the USB or search for new hardware in the device manager again);

The motherboard USB driver is not installed or is not completely installed or conflicts with the installation of other devices (can be found in the device manager);

It is more common in XP systems, because the system's query scan of the USB port stops, making the system unable to recognize the new hardware.

You can right-click on the desktop My Computer and select the properties menu ------- point hardware ------ point device manager ------- double-click the serial bus controller --- ----- Click the "Operation" menu ----- click "Scan for hardware changes" and wait for the scan to end. If you see the new USB device in the universal serial bus controller, it means that it is connected with the PC normally. If no new hardware can be found, it means that MP3 / MP4 cannot communicate with the PC. If new hardware is found but there is a conflict (exclamation or question mark in front of the new hardware), you need to right-click on it and then delete the new hardware until There is no conflict, if there are still conflicts, it means that there is indeed a problem with the MP3 / MP4 system, and the computer USB cannot correctly identify the MP3 / MP4 system.

Switch on and off problems

The LCD will only display the words ERSS REFORMAT when it is turned on, and then it will automatically shut down.

The problem is caused by formatting the MP3 / MP4 machine in the Windows XP system, using the XP system's FAT32 format (the default value is FAT32) to format MP3 / MP4.

The format does not support the flash MP3 / MP4 storage format, and do not select the quick format option in the format options. Quick format just clears the data in the memory, there is no change to the format in the memory, so the formatting is also meaningless;

If it is formatted by FAT32 by mistake, the LCD will display EERS REFORMAT after restarting, or it will not start at all. At this time, you need to reconnect the machine, select FAT in the file system option of the Windows XP system format interface, and then format it. (In WINDOWS98 and WINDOWS2000 systems, you can use the default formatting in the formatting interface.)

(If you can't solve the problem, you can use the initialization program to re-initialize and restore the factory settings. For details, see Program Initialization Update.)
