Exam 220-1101 topic 1 question 264 discussion

B The most likely cause of the issue is that the laptop has a swollen battery, which is a condition where the battery expands due to gas buildup inside the cells. A swollen battery can cause physical damage to the laptop, such as pushing against the track pad or keyboard and preventing them from functioning properly. The technician should inspect the battery and replace it if it is swollen. A damaged digitizer is not the cause of the issue, as the digitizer is a component that converts touch input into digital signals, and it does not affect the

I agree with [Removed] on the chosen Answer B. The described symptoms; where the user is unable to click the buttons on the trackpad or press some keys on the keyboard without any visible physical damage, are highly possible issue of a swollen battery.

B. Swollen battery: A swollen battery is a common issue in laptops that can cause physical damage or pressure on internal components. If the battery is swollen, it can push against the trackpad and/or the keyboard, causing malfunctions such as the inability to click the trackpad buttons or use certain keys. The fact that no external physical damage is observed on the laptop points to an internal issue, which is often the case with a swollen battery. C. Distended capacitors: Distended capacitors could cause electrical problems, but they would typically affect the functionality of the laptop in more severe ways, such as preventing it from powering on or causing intermittent failures in the system. The issue described here is more localized to the trackpad and keyboard, which makes swollen battery more likely. Thus, a swollen battery is the most likely cause of this issue.

While distended (bulging) capacitors can cause system instability, they are more likely to result in system-wide failures (e.g., no power, random shutdowns) rather than isolated keyboard or trackpad issues.

"Distended capacitors" is replaced by "An open bottle of rubbing alcohol fell onto the keyboard." Would that change Anything? I have a feeling not, but I just want to make sure

Based on the symptoms described, the most likely cause of the issue is option C: Distended capacitors. Distended capacitors on the motherboard can cause various malfunctions in electronic devices, including problems with input devices like trackpads and keyboards.
