The disc drive does not read and stops after two rings The disc has been used before, and the notebo

This optical drive is not afraid to use it, but it is afraid to put it.,It's not used for a long time, and there will be problems in general.,Take it and fix it.。

There are several main possibilities for the disc drive not to read the disc: 1. Disc quality problems - some discs, especially burning discs, are of poor quality, or used for a long time, the disc surface is dirty, scratched, and the disc is deformed (uneven), etc., resulting in poor beam focusing and error in reading the disc; 2. The surface area of the laser head focusing objective lens is reduced by dust or aging transparency; 3. The surface of the track (sliding shaft) of the laser head seeking trolley becomes unsmooth due to the lack of dust accumulation for a long time, which hinders the trolley's travel; 4. The internal contact of the laser head reset switch is oxidized and the contact is poor, the laser head cannot be reset normally, and the reading disk is wrong; 5. The focus coil bracket of the laser head objective lens is deformed (sinking), and the beam cannot be focused; 6. Aging of laser head; 7. Spindle motor failure; 8. The circuit board of the optical drive controller is faulty.

Under amateur conditions, the following methods can be taken for simple maintenance: 1. Clean the laser head objective lens - use clean absorbent cotton and gently wipe the lens (methyl ether can be used, but alcohol cannot be used); 2. Clean the track of the laser head seeking trolley to make it bright and lubricated; 3. Use a special cleaner (such as Lexset) to clean the laser head reset switch. On this basis, switch to a good quality disc test reading plate to see if it returns to normal.

If it is still abnormal, you need to ask a friend with maintenance experience to help further repair the optical drive disassembly, or send it to a professional maintenance department.

Change a disc to test if you can, it means that your original disc has a problem and the quality is not good, otherwise, your optical drive is faulty, you can wipe it, otherwise you will have to change the optical drive.

Use a lens cloth to wipe the ash of the laser head to see if it can be normal, if it is not normal, it means that the optical drive is aging, and the optical drive can only be replaced.

The laser head of the optical drive is relatively fragile, so I suggest you deal with it according to the method I mentioned above.

How long has it been used, it is estimated that the optical drive has aged.

The optical drive is broken. Let's get a new one or a USB flash drive. Don't look at yellow discs in the future.

It should be that the optical drive is aging, what brand of optical drive.

There are many reasons why an optical drive doesn't read discs.

Clause. 1. If your optical cherry power supply does not flash and rotate, it means that there is a problem with the power supply of your optical drive, so unpack and replug the power cable. If it doesn't work, you have to change.

Clause. Second, your optical drive power light flashes, but you can't hear the sound of the disc turning, which means that you have a problem with the servo motor, you can replace one, or throw the whole thing out of your home.

Clause. 3. The power light of your optical drive flashes, and you hear the disc rotating at high speed, but you don't read it**.

1.Try a few more**.

2.It could be that the laser mount slide shaft is out of oil or stuck. Clean the metal shaft and add some oil.

3.It may be that the laser head is not clean. You can wipe it with clean water. You can't use alcohol...

4.The laser head Lao Tong touched, you can increase the output power of the laser head, there is an adjustment screw behind the laser head card holder, slowly rotate about 15 degrees, if not, turn 15 degrees, and try repeatedly until you can read the film...

There is a possibility of this, but it may also be that the disc is broken (you can test it on other computers), and it is also possible that the signal cable or power cable of the optical and silver hand drive is in poor contact with the optical drive and the motherboard, you can check whether the connection between them is normal and effective before the fight.
