Ann, a technician, is taking apart a laptop to replace some components. Which of the following will allow Ann to put the laptop back together properly and in a timely fashion?

Having an identical laptop for comparison is helpful but often impractical, and does not directly track where each individual screw originated in the unit being serviced.

Laptop disassembly involves many different-length and different-diameter screws that are not interchangeable. Placing wrong screws in wrong holes can damage threads or fail to secure components properly. Labeling each screw with its location as it is removed - using tape, small bags, or a diagram - eliminates guesswork during reassembly, saving time and preventing mistakes.

A magnetic screwdriver helps prevent dropping screws but provides no information about which screw belongs in which location.

A second technician adds manpower but does not solve the organizational problem of tracking screw placement during a complex disassembly.
