The correct answer is C. The battery.

The battery is the component that stores and provides electrical power to the phone. The battery can degrade over time and lose its capacity to hold a full charge. This can cause the phone to stop charging at a certain percentage and run out of power faster. To resolve this issue, the battery should be replaced with a new one that is compatible with the phone model and manufacturer.

To replace the battery, the customer may need to follow different steps depending on the type of phone and battery. Some phones have removable batteries that can be easily accessed by opening the back cover of the phone and sliding out the old battery. Other phones have non-removable batteries that are sealed inside the phone and require special tools and skills to open the phone and disconnect the old battery. In this case, the customer may need to contact the phone manufacturer or a professional service center for assistance.

One of the possible causes of the error message “No input source” is that the LCD projector is not receiving any signal from the connected device, such as a laptop1. This could be due to a loose or faulty cable or connector, or an incorrect input source selected on the projector2. Therefore, the first troubleshooting step that the technician should take is to check the physical cabling and make sure it is properly connected and secured12.

The technician is unable to access the company portal website, but other websites work fine. This suggests an issue with resolving the specific URL of the company portal, which is a function of DNS.

Here's why other options are not the most likely cause:

DHCP reservations: This is not relevant as the issue persists even when the technician tries a different workstation, indicating a problem beyond individual device configuration.

Static IP addresses: Similar to DHCP reservations, static IPs are not likely the cause as both affected workstations are experiencing the issue.

Default gateway: While the default gateway is necessary for internet access, other websites are working, making it less likely to be the root cause.

The internal antennas are the components that allow the laptop to receive and transmit wireless signals from and to the wireless access point. The internal antennas are usually located inside or around the laptop screen, and they are connected to the wireless network card or adapter by thin wires or cables. If the internal antennas are disconnected, damaged, or misaligned, the laptop may experience wireless connectivity issues, such as low signal strength, limited range, or intermittent connection.

In this scenario, a customer reports that, after a technician replaced a laptop screen, the laptop is only able to connect to a Wi-Fi network if it is positioned very close to a wireless access point. This could indicate that the technician accidentally disconnected or damaged the internal antennas during the screen replacement process, and that the laptop is not receiving enough wireless signals from the wireless access point. Therefore, the first thing that the technician should verify is that the internal antennas are properly connected and positioned inside or around the laptop screen.

To verify and reconnect the internal antennas, the technician should follow these steps :

Turn off the laptop and disconnect it from any power source or external device.

Remove the battery and any screws that secure the laptop screen bezel.

Carefully pry off the laptop screen bezel and expose the internal antennas.

Check if the internal antennas are intact and securely connected to the wireless network card or adapter. The internal antennas may have different colors or labels, such as black, white, gray, main, aux, or 1, 2.

If the internal antennas are disconnected or loose, reconnect them to the corresponding connectors on the wireless network card or adapter. Make sure that they snap into place and that there is no gap or bend in the wires or cables.

If the internal antennas are damaged or broken, replace them with compatible ones. Make sure that they have the same length and shape as the original ones.

Realign and reposition the internal antennas inside or around the laptop screen. Make sure that they do not interfere with any other component or cable, and that they follow the original path and direction.

Reattach the laptop screen bezel and secure it with screws.

Reinsert the battery and turn on the laptop.

Test the wireless connectivity and performance of the laptop.
