1, the system will not automatically detect the optical drive.
The main reason is that the automatic detection function is disabled in the system device manager. Generally speaking, it is automatic detection, but some optimization tools will directly set these ides to not automatically detect, so there will be a problem that the optical drive cannot be found.
2. The motherboard BIOS has disabled the optical drive.
There are some settings in the motherboard BIOS, which are mainly used to automatically detect the IDE interface on the motherboard interface. If the function of automatically detecting IDE interface is turned off, the computer will also fail to detect the optical drive.
3. The power cord and/or data cord of the CD-ROM drive are not inserted correctly.
In addition to the above reasons, when the data cable or power cable of the optical drive in the main chassis is not correctly inserted or loose, the failure of the optical drive cannot be detected. However, if the eject button on the CD-ROM drive can eject normally according to the manifestation of the fault, it should be the reason why the data cable of the CD-ROM drive is loose or damaged.
2. What if the CD-ROM drive doesn't open?
First, remove the optical drive.
1. Front panel removal
First cut off the computer power supply, then disassemble the chassis, take the optical drive out of the 5.25-inch optical drive slot, and unplug the corresponding IDE data cable and audio cable. Find a toothpick, or something like thin wire, insert it into the emergency pop-up hole of the CD-ROM drive and open the door of the CD-ROM drive to facilitate the next disassembly.
There is another way: when the computer is turned on, let the CD-ROM drive bounce off and then cut off the computer power supply, but it is more troublesome to remove the CD-ROM drive from the chassis. After the door of the CD-ROM drive is opened, on the left and right sides of the CD-ROM drive, you will find that the front panel of the CD-ROM drive is made of two small plastic clips, which are glued to the outer shell of the CD-ROM drive. Hold down the clip by hand, and then pull open the front panel, thus completing the removal of the CD-ROM panel.
2. Disassembly of the shell
There are two screws on the left and right around the CD-ROM drive housing, and four screws on the bottom. Remove them one by one with a screwdriver, and then separate the upper and lower shells. In this way, the shell of the CD-ROM drive is opened, and the internal structure of the CD-ROM drive is basically presented. What needs to be added is that some CD-ROMs have special screw models and the "+"slot is shallow, so the commonly installed screwdriver can't work. When disassembling, be sure to pay attention to the uniform stress. If we are not careful, the screw may slip, which is not easy. After removing the upper shell, you will see an iron plate covering the optical head assembly with a round object in the middle to fix the optical disc. When the spindle motor of the CD-ROM drive starts to rotate, it will move upward and closely adhere to the clamping plate to fix the CD, and then rotate at high speed.
3. Disassembly of the circuit board
At the bottom of the optical drive is a green PCB printed circuit board. It has the cache, decoding chip, BIOS and other components of the CD-ROM drive. In addition, a data cable is led out from the PCB circuit board, and the other end is connected near the laser head of the CD-ROM drive and the control circuit of the warehouse door, so be sure to pay attention when disassembling. The circuit board is usually fixed on the iron shell at the bottom of the CD-ROM drive with screws. After the screw is removed, the circuit board is separated, but there are several white data lines connected to the optical head assembly and other equipment. Unplug the data cable carefully, and be careful not to break the data cable (because the data cable in the CD-ROM drive is an ide hard disk cable). Now the PCB circuit board has been completely separated from the optical head assembly. Cleaning the PCB circuit board We can gently brush off the dust on the PCB circuit board with a brush.
4. Disassembly of motor and optical head
The laser head of an optical drive is generally composed of two parts, one is a laser lens and the other is a laser head. But at present, some optical drives directly combine the optical head and lens into one, which is easier to disassemble. There are two kinds of motors for optical drive: one is the spindle motor that drives the laser head to move and read the optical disc; One is a servo motor that drives the door of the CD-ROM drive in and out. Some optical drives are independent, while others are unified. It is convenient to remove the motor, just remove the power supply circuit and the fixing screws.
Second, the CD-ROM drive cleaning and laser head power adjustment
1. Cleaning of gear transmission equipment
Old-fashioned optical drives, such as those under 24*, are mostly driven. Due to thermal expansion and contraction, belt drive is prone to failure. The phenomenon that the CD-ROM door slips and gets stuck is mostly due to the aging of the belt. In this case, it is only necessary to replace the new belt. The gear-driven optical drive is easier to maintain. If the gear is broken or badly worn, just replace it with a new one. If it is used for a long time, the gear can be lubricated, which can reduce the wear of the gear and extend the service life of the optical drive to a certain extent. Note that when lubricating the gear and transmission shaft, do not touch the optical head assembly (it is best to use solid lubricating oil instead of liquid lubricating oil).
2. Cleaning of laser head assembly
Generally speaking, the phenomenon that the optical drive does not read the disk, or the disk reading is not good, is mostly caused by too much dust in the laser head. Cleaning the laser head is the most troublesome place in the whole process of cleaning the optical drive. The bald lens is generally next to the spindle motor, and it is something the size of a light blue mung bean. This blue laser lens is fixed on an elastic object, so be careful not to use too much force when wiping, or the head will deviate. Conditional friends can use a magnifying glass to see how much dust there is on the bald lens before wiping it. If it is less, gently wipe it with a cotton swab. If there are many, you can wipe them with a cotton swab first, and then clean them with the solution. It is best to use high-purity anhydrous ethanol as the solution to scrub the CD-ROM drive. Some people think that ethanol will dissolve the coating on optical lenses. In fact, the coating on the bald lens is made of magnesium fluoride, and the function of magnesium fluoride film is to reduce refraction and increase transparency. However, anhydrous ethanol will not dissolve magnesium fluoride at all, so it is a bit exaggerated to say that cleaning the lens of laser head with ethanol will dissolve the organic coating. Tell me more about cotton swabs. There are too many fibers on the medical cotton swab, which is absolutely unacceptable. Smaller ones can be sold in supermarkets. If you really can't find such a cotton swab and there is not much dust in the laser lens, you can also find a new cigarette, pull down the filter, tear it from the middle, remove the outer circle of paper to expose the filter line, fold it in half, and then wipe the lens with the filter line on the filter.
3. Adjust the laser head power
Next to or below the laser lens, there is usually a mung bean-sized potentiometer. It changes the current by increasing or decreasing the resistance, thus adjusting the emission power of the laser head. It looks a bit like a screw cap and can be adjusted with a small screwdriver or a small screwdriver for repairing clocks. Adjust clockwise or counterclockwise, with 5 degrees as the benchmark. Turn on the power of each regulator and check the reading effect of the CD-ROM drive until it is satisfactory. But remember not to adjust too much, too much power will cause the laser head to burn out.
3. What if the computer CD-ROM doesn't open?
Computers are very common in our daily life, so people may encounter various problems when using computers, and the inability to turn on the CD-ROM drive is one of them.
Whether it is a notebook computer or a desktop computer, the optical drive is very necessary. So, what if the CD-ROM drive doesn't open? This is a small problem in the use of computers. It's too much trouble to take it to the garage. You'd better know the solution yourself. If you are interested, you can follow me to find out the solution that the computer CD-ROM can't be opened.
The computer CD-ROM won't open. Solution 1 First, let's try the commands on the notebook operating system to see if we can turn on the CD-ROM drive. Find the CD of my notebook in my desktop computer, then click the right mouse button and select Eject from the drop-down menu to know whether it can be opened.
There is another way to eject the CD-ROM drive. Press the button next to it. If neither works, then I suggest the reader find a toothpick and poke the hole next to the CD-ROM drive. That's the mandatory button to leave the warehouse. If the above two methods can't make the optical drive eject, then I can only tell you unfortunately that your notebook optical drive is broken.
If you don't often use the CD-ROM drive, you should regularly clean the dust on the CD-ROM drive to prevent it from bouncing off. The computer CD-ROM won't open. Solution 2 If there is a yellow exclamation mark (error code? 19), indicating that the computer optical drive is out of order.
You can use the driver wizard CD repair tool Lae to repair the computer CD. The method steps are to install the driver wizard, open the treasure chest of the driver wizard, select "CD-ROM repair", and then click the "one-button repair" button according to the prompt, and the system will automatically repair the CD-ROM fault for you.
The solution that the computer optical drive can't be opened is the solution that the optical drive can't be opened. First, open the baffle in front of the CD-ROM drive, find a hole on the right side of the CD-ROM drive, and push it inward with a thick needle to make the CD-ROM drive frame pop out of the CD-ROM drive box; Then, you can put a useless CD into the CD-ROM drive, then turn off the CD-ROM drive, and then the CD-ROM drive can be turned on. Note that when you don't use the CD-ROM drive in the future, you must flip a CD in the CD-ROM drive, or you will open the CD-ROM drive with a needle.
How to install the computer CD-ROM 1? First, we remove the bezel above the computer mainframe. Usually there are two screws to fix it, just unscrew it, and then pull out the baffle. We can remove the baffle on the side of the motherboard with fewer sockets.
2. Usually, when you buy an optical drive, you will send a SATA serial data cable. We can see from the back of the CD-ROM drive that the current CD-ROM drive usually has two interfaces, one is the data line interface of the CD-ROM drive and the other is the power line interface of the CD-ROM drive. Nowadays, the interface is usually not wrong, and it has anti-plug design. If the data cable is in the wrong direction, it cannot be inserted.
4. On the motherboard of the computer, you can see the SATA interface of the motherboard, one is to connect the serial hard disk, and the other is to connect the computer CD-ROM. You can also connect a data cable between the CD-ROM drive and the hard disk.
Usually STAT 1 is connected to the hard disk, and SATA2 is connected to the optical drive. Here, in order to let everyone see the connection method clearly, let's connect it first. One end of the data cable is plugged into the computer SATA interface, and the other end is plugged into the data cable interface of the CD-ROM drive.
6. We can find the flat power cord interface to connect the CD-ROM drive or hard disk on the computer's own power supply. We just need to connect this power cord to the CD-ROM drive.
It's simple. You can operate it yourself. 7. After we know how to connect, now we just need to remove the plastic baffle on the top of the front of the computer case, and then insert the CD-ROM drive into the computer from the outside.
8. We fixed the CD-ROM drive and the host with screws, and then correctly connected the power cord and data cord of the CD-ROM drive according to the above introduction, thus completing the installation of the CD-ROM drive. Through the above introduction, I believe everyone knows the solution that the computer CD-ROM can't be opened.
Literally, the solution to the problem that the computer CD-ROM can't be opened seems complicated, but it will be found very simple in practice. CD-ROM drive is an important part of computer, so it is very necessary to repair the damaged CD-ROM drive.
