A technician is replacing the front-facing camera in a laptop. After installation, the camera is not detected by the operating system. The technician has already verified the camera is the correct part. What is the most likely cause?

The camera is incompatible with the laptop's operating system version.

The camera driver needs to be reinstalled from the manufacturer's website.

The laptop's BIOS needs a firmware update to recognize the new camera.

The camera's ribbon cable is not fully inserted into the motherboard connector.

A field technician is replacing a user's smartphone battery. After disconnecting the old battery, the technician notices a small, thin cable routed along the battery compartment that was not attached to the battery. The technician must ensure the new battery installation does not interfere with this cable. What is the most appropriate action?

Apply adhesive tape over the cable to secure it directly to the top of the new battery.

Route the cable in its original channel or alongside the new battery, ensuring it is not pinched when the battery is seated.

Remove the cable entirely, as it is a redundant antenna lead that is not needed after battery replacement.

Disconnect the cable and tuck it under the new battery to keep it out of the way.

A technician is replacing a cracked rear camera lens on a smartphone. After removing the old lens, the technician notices a small rubber gasket around the camera module. What should the technician do with the gasket?

Apply superglue to the gasket to ensure a permanent seal.

Replace the gasket with a thicker one from another phone model to improve sealing.

Reuse the gasket if it is undamaged, and ensure it is properly seated before installing the new lens.

Discard the gasket, as it is only for shipping protection.

A technician is replacing a battery in a tablet. After installing the new battery, the tablet powers on but shows a 'Battery Temperature Too High' warning and shuts down. What is the most likely cause?

The technician left the tablet plugged into the charger during the battery replacement.

The tablet's operating system needs a software update to recognize the new battery.

The battery connector was not fully seated, causing high resistance and heat generation.

The new battery is defective and must be returned to the manufacturer.

A technician is replacing a battery in a laptop. The technician has removed the old battery and is about to install the new one. What is the most important safety precaution to follow?

Use a metal tool to pry the battery out of the compartment.

Ensure the laptop is powered off and unplugged from the AC adapter.

Discharge the battery completely before removal.

Wear an anti-static wrist strap to prevent ESD damage.
