A customer has the LCD display in a laptop replaced. After the repair, the customer notices the laptop is showing a weaker WiFi signal than before the display was replaced. Which of the following BEST explains the lower WiFi signal?
A.
The antenna is too close to the screen's power inverter.
if the atenna was damaged, its not possible to access signal the question states having weaker signal. i think that is not the standard lcd thats why its causes interference
A. The antenna is too close to the screen's power inverter.
This is a possible explanation for the weaker WiFi signal. The screen's power inverter can generate electromagnetic interference that could interfere with the radio signal. If the antenna is too close to the power inverter, this could cause a weaker WiFi signal.
B. The new LCD panel is causing interference.
This is possible, but less likely. LCD panels are not known to generate electromagnetic interference that would interfere with a WiFi signal.
C. The digitizer is calibrated improperly.
The digitizer is used to sense touch input on the screen and would not directly affect the WiFi signal.
D. The radio antennas are damaged.
This is possible, but if the antennas were damaged, the WiFi signal would likely not work at all.
Therefore, option A is the BEST explanation for the weaker WiFi signal.
Just a question when u replace a lcd it has to be the same specification as the old one right? I am guessing that D is the answer its very vague deze question.
Yeah, I picked A at first. Then felt like I should've put that the antenna was damaged. But LCD interference? I looked it up and it happens but I wouldn't have thought
