Correct answers: A, B, D
Explanation
Unexpected shutdowns on battery power can often be resolved by troubleshooting the battery and power management system. Calibrating the battery ensures accurate charge readings, while verifying power management settings can help identify improper configurations. Updating the BIOS/firmware can resolve compatibility issues. Immediate battery replacement or changing to a performance power plan are unnecessary steps without proper diagnostics.
- A. Correct.
Calibrating the battery can help the system accurately report the battery's charge level, which might resolve the issue of incorrect battery percentage readings.
- B. Correct.
Power management settings control how the laptop uses power. Verifying these settings can help identify configurations that may lead to unexpected shutdowns.
- C. Incorrect.
Replacing the battery immediately is not the best first step. Troubleshooting should be done first to confirm the battery is faulty.
- D. Correct.
Updating the BIOS/firmware can resolve compatibility issues between the laptop and the battery, potentially fixing power management problems.
- E. Incorrect.
Setting the laptop to 'High Performance' mode prioritizes performance over power savings but does not address the issue of unexpected shutdowns caused by incorrect battery readings or power management problems.
