What caution should be taken when working on a laptop or device that may be under a warranty?
What will be an ideal response?
The warranty often applies to all components in the system, but it can be voided if someone other than an authorized service center services the laptop. Therefore, you, as a service technician, must be very careful not to void a warranty that the customer has purchased. Warranties can be voided by opening the case, removing part labels, installing other-vendor parts, upgrading the OS, or disassembling the system unless directly instructed to do so by the authorized service center help desk personnel. Before you begin servicing a laptop, to avoid problems with a warranty, always ask the customer, "Is the laptop under warranty?" If the laptop is under warranty, look at the documentation to find out how to get technical support. Options are chat sessions on the web, phone numbers, and email. Use the most appropriate option. Before you contact technical support, have the laptop model and serial number ready. You'll also need the name, phone number, and address of the person or company that made the purchase. Consider asking the customer for a copy of the receipt and warranty so that you'll have the information you need to talk with support personnel.
