Upon replacing a hard drive in a laptop with an externally accessible drive bay, what should you do after powering down the system? (Select two)

Remove the battery
Unplug the AC power
Remove the hard drive enclosure screws
Boot the system without the hard drive

The correct answer is: Remove the battery

After powering down the system, it is essential to ensure safety and prevent potential damage to both the laptop and the new hard drive. Removing the battery is a crucial step in this process, especially for laptops with externally accessible drive bays. By removing the battery, you eliminate any chance of power being supplied to the laptop, which protects the internal components and ensures that no electrical shorts can occur during the replacement. This step is particularly important because it allows for safe handling of the internal components without the risk of accidental power surges. Additionally, unplugging the AC power is another critical action to take. Just like removing the battery, disconnecting the AC power ensures that all power sources are cut off, providing an added layer of safety. It also helps in grounding the system, preventing static electricity from potentially damaging computer components during the hard drive replacement. Therefore, taking both of these steps—removing the battery and unplugging the AC power—guarantees a safe environment for working on the laptop's hardware, reducing the risk of complications that could arise during the hard drive replacement process.
