A technician is replacing a battery in a laptop. The original battery is held in place by adhesive strips. After removing the old battery, the technician notices a small amount of adhesive residue remains in the compartment. What is the best practice before installing the new battery?

Use a metal scraper to remove the residue quickly.

Leave the residue, as it will help the new battery adhere better.

Install the new battery directly over the residue without cleaning.

Clean the residue with isopropyl alcohol and allow it to dry completely.

A technician is replacing a rear camera module on a tablet. The new camera module has a small piece of protective film over the lens. What should the technician do?

Remove the film and wipe the lens with a cotton swab dipped in water.

Remove the film just before closing the device to prevent dust from settling on the lens.

Remove the film and clean the lens with a glass cleaner containing ammonia.

A technician is replacing the Wi-Fi antenna in a smartphone. After reassembly, the phone shows full signal bars, but the Wi-Fi connection drops intermittently. What is the most likely cause?

The phone's Wi-Fi MAC address has changed and needs to be re-registered.

Reinstall the old camera module to see if the Wi-Fi issue is related to the new camera.

Replace the Wi-Fi antenna and route the new antenna cable exactly as the original was routed.

Reset the phone's network settings to clear any Wi-Fi configuration errors.

Update the phone's firmware to improve Wi-Fi radio performance.
