If you are having problems with the lens on the CD/DVD drive in your laptop, it is possible to safely clean the lens with a simple device available in most computer and electronics stores.
Initial troubleshooting will help you confirm whether the lens in your laptop's CD/DVD drive needs cleaning. If you are having trouble reading a CD or DVD, the disc itself may be scratched. Cleaning the lens won't help this situation. Try another CD -- if the problem persist, then proceed with cleaning the drive lens.
First, try cleaning your CD/DVD drive with a can of compressed air. This product can be purchased inexpensively at most electronics stores and is handy to have for a number of computer issues. Open the drive and gently spray the interior of the unit with compressed air to remove any dust particles. Then insert the disc again and see if it can be read. If not, continue to the next step.
CD/DVD lens cleaner
You can purchase a CD/DVD drive lens cleaner kit from most electronics stores. Shaped like a regular CD, you insert the cleaning disc into the drive and it cleans the unit using gentle brushes, a chemical solution or other means, depending on the specific product. Follow the instructions on the package. Then try to read a CD or DVD. If this does not work, your CD/DVD drive may need to be replaced. Take your laptop to the repair shop for service.
