Compare the system board display connections with a properly functioning laptop. b. Document and label the location of the screws and cables before removing them c. Backup the data immediately in case the problem is related to the hard drive. d. Organize and place all parts and screws and in one place e. Charge the laptop battery pack so it is ready to return to the customer with a full charge.
b. Document and label the location of the screws and cables before removing them. d. Organize and place all parts and screws and in one place. (While most desktop computers contain only one or two types of screws, a laptop may have a variety of screws and washers in various sizes and lengths. It is imperative that a technician document and label screws and cables before removing them. Inserting a screw that is too long may penetrate a cable or circuit board and cause damage. Inserting a screw that is the wrong size can also strip the threads, causing the correct-sized screw not to tighten properly. Documenting and labeling locations will assist in reassembling the unit.) (After documenting and labeling the location of the parts and screws, the technician needs to organize them and keep them in one place. Doing so will assist in reassembling the unit.)

These cables will need to be disconnected prior to removal of the keyboard.) (The keyboard bezel is a part of the plastic covers of a laptop and is the cover that surrounds the top of the keyboard. For some laptops, the case top covers the keyboard. Regardless of whether the cover is the bezel or the case top, it will need to be removed first in order to remove the keyboard.)
