Explanation
To optimize battery life on a laptop, IT support technicians should focus on reducing power consumption by enabling power-saving settings, disabling unnecessary features or applications, and minimizing hardware usage. Adjusting display brightness to a lower level and managing system activity are essential practices to extend the battery life of devices.
- A. Correct.
Enabling a power-saving mode or battery saver feature reduces system performance and limits power usage, which helps in conserving battery life.
- B. Correct.
Disabling unnecessary background applications and processes reduces CPU and memory usage, resulting in lower power consumption.
- C. Incorrect.
Setting the display brightness to maximum increases power usage significantly and is not recommended for optimizing battery life.
- D. Correct.
Configuring the laptop to enter sleep mode after a shorter period of inactivity ensures that the device consumes minimal power when not in active use.
- E. Correct.
Disabling Wi-Fi and Bluetooth when not in use reduces power consumption as these features require energy to remain active.
