When you purchase a computer, laptop, or screen, manufacturers usually provide a limited warranty. This warranty typically lasts for at least 90 days and can be valid for up to five years. It usually covers defects in materials and workmanship, but not accidental damage. Accidental damage is any damage that is not the direct result of a manufacturing defect or failure.
It is usually caused by an involuntary act such as a fall or an impact on the LCD screen or any other part of the product. This type of damage is not covered by the standard product warranty and is only included in an optional add-on to the basic product warranty, known as the accidental damage service offer. It is important to note that accidental damage should not be confused with occasional dead or stuck pixels on the LCD panel. If you experience this issue, Dell has guidelines on how to address it.
HP does not recommend repairing or replacing the screen yourself as this can void warranty options and cause further damage to the equipment. If your Dell laptop's LCD panel has been accidentally damaged but is not covered by the accidental damage service offer, contact Dell technical support for repair options. White spots or lighter areas visible on the screen are usually caused by a sharp object or edge coming into contact with it with force. To ensure your laptop lasts for many years, it is important to understand and implement some of the best practices for safely operating it.
This includes avoiding hitting the screen, dropping it, closing the cover while there is an object in the keyboard area, or holding it next to the screen.
