What should I do if the optical drive cannot be played?
The simple solution that the optical drive cannot play is absolutely original and practical.
The old optical drive is usually unavailable. We usually find a needle to solve the problem. However, it is too much trouble to always have a backup root needle next to the optical drive. Here is an absolutely useful method.
When taking out the disc from the optical drive, you can put a phone card to the optical drive, that is, ensure that there is either a disc or a phone card in the optical drive. Try it!
This sentence is true.
I believe you have the experience that the optical drive won't pop up only when there is no CD. What is the difference between playing a CD and not playing a CD? There is a rubber cylinder in the middle of the optical drive to hold the disc. As shown in.

This plug-in is embedded in the middle of the disc, so that the disc does not slide. When the optical drive is closed, the ring is lifted to hold the disc. That is to say, the disc is pressed with this rubber column. Therefore, we put a phone card, which is equivalent to pressing the disc.
Some people may say: Isn't it enough for me to keep a CD in it? No, no. However, when there is a CD in the optical drive, the laser head will try to read the disk after a while. In this way, the start and stop operations are very damaging to the laser head.
