Question 77

Liquid damage is the most likely cause of the laptop's issues.

The presence of small sticker papers that have changed color from red to blue suggests that the laptop has suffered from liquid exposure. These indicators are typically used to signal liquid damage, thus pointing to this as the primary issue affecting the laptop's functionality.

A) Broken screen

A broken screen would not typically cause the laptop to turn off randomly. Furthermore, it would not result in color changes to the internal stickers, which specifically indicate liquid contact. Therefore, this option does not align with the symptoms observed.

B) Liquid damage

The color change of the sticker paper from red to blue is a clear indication of liquid damage, which is known to cause various operational issues, including random shutdowns. This is the most plausible explanation given the evidence found within the laptop.

C) Swollen battery

While a swollen battery can cause operational issues, it does not explain the color change of the stickers. Additionally, a swollen battery is usually visible and would likely prompt other symptoms rather than random shutdowns directly caused by liquid exposure.

D) Overheating

Overheating could potentially lead to random shutdowns, but it would not account for the color change of the stickers. This symptom is specifically associated with liquid damage. Thus, overheating does not adequately explain the situation presented.

Conclusion

The evidence of liquid damage, as indicated by the color change in the stickers, firmly establishes option B as the correct answer. Other options do not adequately account for both the symptoms displayed by the laptop and the observable signs within the device, making them less likely causes of the issue.
