Drivers
What Is a Driver?
A driver is a program that controls a device such as a printer, mouse, or keyboard. All devices require a driver program.
A driver acts like a translator between the device and any other programs that use the device. Each device has its own set of specialized commands that only
its driver recognizes.
Dell ships your computer to you with required drivers already installed—no further installation or configuration is needed.
Option Function
Express Test Performs a quick test of devices. This test typically takes 10 to 20 minutes and requires no interaction on your part. Run Express Test first to
increase the possibility of tracing the problem quickly.
Extended
Test Performs a thorough check of devices. This test typically takes an hour or more and requires you to answer questions periodically.
Custom Test Tests a specific device. You can customize the tests you want to run.
Symptom
Tree Lists the most common symptoms encountered and allows you to select a test based on the symptom of the problem you are having.
NOTE: The Service Tag for your computer is located at the top of each test screen. If you contact Dell, technical support will ask for your Service Tag.
