Speaking of laptop drive, many people love and hate it. It is quite easy to use when you buy it back. But after you have been using it for a long time, you can't read the CD. Is the laptop drive useful? What if I can't read the CD? Let's take a look at the decoration home decoration network Xiaobian.
Is the laptop drive useful?
1, look at the need: Now everyone may prefer to watch videos online, listen to music, software games are downloaded, the use of CDs is very rare, so the general situation is not a CD-ROM is a way to save money. But you definitely use the optical drive, and you definitely buy a CD-ROM drive.
2, the use is not convenient: now mobile hard disk 1t is also very cheap, easy to save the data in the mobile hard disk to carry it convenient, and as long as the computer has a usb socket, you can read the data, the number of CDs is increasing More, and no optical drive is also troublesome, but also to burn.
3, u disk and mobile hard disk : these years u disk and mobile hard disk prices drop, many people like to put data on the u disk, easy to carry, and can repeatedly write data, mobile hard disk and meet the preservation of a large amount of data, usb interface Form the current mainstream interface, the computer must bring, you do not have to worry about reading. In the past, it was still possible to reinstall the system on the CD. Now it is more convenient to reinstall the u disk and reinstall the hard disk.
4, notebook with CD-ROM: Personally think that just add weight and volume to the notebook, the notebook is just more convenient to carry out some office and watch video entertainment, smaller size, lighter, well, or that sentence if you work and live A CD must be needed, and all of the above are nonsense.
5, external optical drive: life is still a lot of CD and cd what needs, such as some software CDs, game CDs, tutorial CDs, in order to meet this need to have an external optical drive, in fact, this is not more convenient, now many of the home are Notebook + desktop, but if you have to bring a CD-ROM drive, desktop + notebook with a CD-ROM drive price is much more expensive, or just a belt, then sometimes it is not very convenient to use,
How to open the laptop drive?
1, the hardware switch is turned on:
The laptop optical drive is our usual device, and it also has an open switch. It is usually in the middle of the outside of the optical drive. Or on his left side, look carefully and find it, and at this time, we only need to press the switch, the CD-ROM drive can be opened automatically.
2 , the system software pops up:
First, open the computer on your desktop. Then find the CD-ROM icon in "Computer". This is based on your own hardware, some are DVD drives, some are CD drives, just look for the right, the details do not care too much. Right click on " DVD Drive" and find "Eject" to open the CD-ROM drive and it will pop up automatically.
What should I do if the laptop CD-ROM cannot read the CD?
1. Wipe the laser head with a dry cotton swab : press the eject button of the optical drive to open the optical drive. Gently wipe the lens of the laser head with a cotton ball or cotton swab. Even if it is not used for a long time, due to the ash inside the notebook, a lot of dust will accumulate on the lens of the optical drive. With the finger on the optical drive tray, the fingertips will be covered with dust.
2 , then clean the laser head with anhydrous alcohol : If the first step is not effective, then you need to put your hands down, wipe the laser head lens with absolute alcohol, then clean with pure water, and finally dry. Be careful not to let liquid drip onto the board during this time. Some people say that alcohol can corrode lenses or coatings. It can be operated many times, and there is no precedent for dissolution.
3 , remove the fixing screw to remove the optical drive : At this time put the disc, if the reading or writing disk still does not improve, then continue to look down. Eject the optical drive tray and close the notebook. Turn the notebook over and open the cover of the optical drive assembly behind the disc tray.
4 , find the adjustment resistor : find the adjustment resistor in the optical drive component. If you have studied electrical electronics, you should know that the potentiometer is roughly long. If you haven't learned it, it doesn't matter. Some optical drive adjustment resistors are on the back of the laser head, some are on the side, and of course some optical drives can't find the adjustment resistor.
5 , adjust the potentiometer : first adjust the adjustment resistance clockwise, roughly rotate 5-10 degrees ; turn on to see if there is any improvement, if not, continue to adjust once. If it still doesn't improve, please adjust it counterclockwise to the initial position, then adjust it 5-10 degrees counterclockwise to see if it improves.
