The display of the system disk is likely to be:

1. Connect to the PC, a removable disk letter appears, and back up the files in the user disk (only the user disk appears at this time). Then format.

2. Note: This step is the key: do not disconnect the small machine (MP5) from the PC normally, unplug the cable directly, and then connect it to the PC.

3. At this time, the system disk should probably be able to appear. (However, if the operating system is Windows XP or Windows 2000, it may not appear, and it should be **Microsoft official patch at this time).

+ The reasons why you can solve it yourself are as follows: 1 is a problem with the battery! In general, it is!

You can rule it out, and the solution: connect to a computer or a charger! If there is a response, it is recommended to unplug the data cable after half an hour!

If it freezes, then the battery must be broken! It has to be replaced to fix it! This operation is the elimination method for repairing the battery!

So it's better to imitate it! 2 is the problem of the data cable! In other words, there is no way for the data cable to work properly, resulting in no way to charge!

Solution: You have to replace the data cable to know if it is caused by this reason! Replacing it can also eliminate some *** problems that can't connect to the computer!

If the computer can't recognize it, replace it! Generally solvable! 3 is a problem with the interface!

Generally, it is a false soldering of the pin caused by too long use! This corruption can also lead to data connection issues! That is, the computer can't recognize the machine!

There is a way to rule out this situation. The solution: connect to your computer!

Shake a few times at the connector! If there is a response, then this test shows that it must be the interface that causes the machine not to boot! Therefore, in this case, it is necessary to use professional tools for soldering (i.e. soldering iron)!

This trial is the most effective! The average maintenance person will do this! Explain the value of action!

4 is the contact piece problem of the interface! It is usually caused by the lack of correct connection in the process of connecting the data cable! Workaround:

You can take a closer look at the interface contact piece! If there is a displacement, it must be replaced immediately! No, you can't connect at a time!

The reasons why I can't solve it by myself are as follows: 5 is the problem of the switch! Generally, if it is broken, the plastic inside has been broken!

The switch must be broken in the off direction, if it is not broken in this direction, the chance of breaking is minimal) If it is not broken, the probability of breaking is even smaller! Solution: This situation can generally only be solved by disassembling the machine and replacing the switch!

6. It is the virtual soldering of the pin of the switch, which is also more common! This is due to contact caused by too long use or backlog! Workaround:

If it is operated by other elimination methods, no abnormalities are found! This is also possible! Virtual welding must be welded with a welding tool!

It must be disassembled! If all of the above reasons are not a problem! That's the part problem, of course!

Therefore, there is no way to solve this situation by people who do not have this technology! You have to find a maintenance person to eliminate the parts! Replace it again!
