Cleaning the laptop is not the only aspect of laptop maintenance and repair. In fact, preventive maintenance can give companies an estimated 500% ROI and save between 12-18% when compared to reactive maintenance. For example, 50% of maintenance costs, as recorded in one study, are "waste", meaning that we are typically paying for issues that may have been saved. Knowing what you need to do to properly maintain your laptop will help you not only from incurring high costs with laptop repair, but also in preventing damage to your laptop.
