Optical drive reading ability drops significantly

Light drive for many years, has been working normally, but the recent use of optical drive, the ability to read the disk significantly decreased. Some of the previously readable discs will now take a long time to recognize. The dust of the laser head was cleaned and the fault was not resolved.

According to the above phenomenon can be judged, the optical drive of the laser head has been aging. It is possible to try to adjust the transmitting power of the laser head to improve the ability of reading disk. The method is: the optical drive is opened, find the potentiometer next to the laser head, use the screwdriver to adjust carefully, counterclockwise rotation 5~10°. Then power on the boot, check the optical drive read disk ability has been improved, otherwise shut down the reverse direction of the adjustment. Adjust this time, not too large, or will burn the laser head. Each time to adjust the time to do a little bit, and then the power-on check effect, you need to adjust it repeatedly.
