General Information

A REQUIRED STEP TO RESOLVE YOUR PROBLEM
Dell will send parts or provide an engineer service only if it has been established that the problem cannot be solved by recommended troubleshooting procedures as outlined below and a Dell representative agrees that a service call would resolve the issue. An exception to this will be made if a customer has special needs or disabilities and makes this known to the Dell technician.
WHAT INFORMATION EACH CUSTOMER SHOULD HAVE WHEN CALLING DELL
Each system shipped by Dell is individually built to order, and the details of that configuration are recorded on Dells call-management system. The customer should identify the service tag number and model number of the faulty system to assist the Dell technician before calling. These can be found on a white label on the back of desktop systems and on the bottom of notebook systems. To complete the diagnostics the customer must have convenient access to the faulty system when calling technical support. The technical support telephone number the customer should call is available at http://www.dell.co.uk/contactus
TROUBLESHOOTING FAULT DIAGNOSIS
For each call, the Dell technician has been trained to undertake a process to ensure the fastest possible resolution. To do this the technician will request the customers assistance to help troubleshoot the problem in order for the technician to diagnose the fault. The diagnostic process will enable the Dell technician to identify the system part that has failed, if any, so that a replacement part can be provided. Examples of what can be included in the scope of the hardware fault diagnostics are: Running diagnostic tests appropriate for the problem reported Installation of service packs, components, supplements, updates and patches for specifically covered factory-installed operating systems, firmware and BIOS Installation and default configuration of Dell factory-installed operating systems, application software and drivers Testing a factory-installed network interface card (including wireless) by testing with manufacturers diagnostics & pinging another PC Testing a factory-installed modem by connecting it to an analogue telephone line (not a PABX line)

The Dell technician will work together with you to ensure that you are properly instructed on how to proceed.

OPENING THE SYSTEM

Accurate problem diagnosis may not be possible without opening the system. Normal troubleshooting procedures may also include opening a system to reseat parts. The Dell technician will inform you if this is necessary and work with you to do so. Opening the system avoids delays in resolution but must be done only with the guidance of the technician who will advise of all necessary safety precautions. As a last resort, the troubleshooting process may require the restoration of the original operating system, software applications and hardware drivers and settings to the original default configuration as shipped from the factory. Software support is limited to basic operating system installation only when required by Dell as part of hardware fault diagnosis and fix, and thereby installing the operating system to factory condition. The service includes installation of Dell drivers and the basic installation and configuration for factory installed OS Service pack, utilities and BIOS issues.

Customer data stored on the defective hard drive will be lost if the hard drive is replaced.
