A user notices that their laptop experiences frequent and unpredictable shutdowns, even when the battery percentage is not low. Which of the following is most likely the cause of these shutdowns?
The most likely cause is system overheating . Laptops have limited internal space and depend on properly functioning fans, heat sinks, vents, and thermal controls. Dust accumulation, blocked vents, a malfunctioning fan, dried thermal compound, or sustained high processing load can cause the internal temperature to increase.
When the CPU or another component reaches a critical temperature, the laptop may shut down automatically to prevent permanent hardware damage. These shutdowns may appear unpredictable because they depend on temperature and workload rather than the displayed battery percentage.
Malware can increase processor usage and indirectly contribute to heat, but it is not the most direct answer.
RAM corruption generally produces crashes, freezes, memory errors, or operating-system stop errors.
Outdated drivers can cause instability but are less closely associated with repeated thermal shutdown behavior.
CompTIA objective 5.4 specifically lists overheating as a common mobile-device issue. Dell also identifies random shutdowns and reboots as symptoms of an overheating laptop.
