Emergency handling method for notebook optical drive not reading disk

A lot of friends have come to reinstall the system or upgrade the system, only to find that the long-used optical drive can not read the disk. Let the disc mad, it is impossible to read the data, and even more than a few months after the new notebook, the quality of the burning disc can not be burned, always prompted the power calibration error. Is it necessary to repair the cost? In fact, it is not necessary, you can simply adjust the CD-ROM drive, let it fight the last drop of blood.

1. Wipe the laser head with a dry cotton swab.

Press the eject button of the CD-ROM drive to open the CD-ROM 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, dried over anhydrous alcohol to clean the laser head

If invalid according to the first operation, then the need to re-hand, with the point over anhydrous Wipe the laser head lens with alcohol, then clean it with pure water (do not use tap water) and dry it. 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 screws remove drive

At this point in the disc, if the disc to write or read the disk is not improved, then it would 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. Friendly reminder, take off the small screws, do not fall into the books, and do not let the sharps scratch the optical drive lens and cable.

4, adjusting the resistance found

found in the adjusting resistor in the drive assembly. If you have studied electrical electronics, you should know that the potentiometer is roughly long. If you haven't learned it, don't worry, look at the picture and look at the picture to find the adjustment resistor. Some optical drive adjustment resistors are on the back of the laser head, some are on the side, and of course some optical drives cannot find the adjustment resistor.

5, the adjustment potentiometer

to adjust the resistance adjustment clockwise, the rotation like a substantially 5-10 degrees; see boot 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.

Postscript: In fact, even without a notebook drive will gradually loss, and in many books, CD-ROM of the warranty period is relatively long, it is recommended optimistic about the warranty period, the time is coming to Change the optical drive to compare insurance. In addition, the room for adjustment of the notebook optical drive is not high, and some notebook optical drives simply have no room for adjustment, and this method is just a drink and thirst, and the need for a moment is not a long-term solution.
