Question

Your friend just gave you his old laptop. Whenever you turn on the laptop, though, a black screen appears and asks you to enter an administrative password before the computer will attempt to boot up. Unfortunately, your friend never gave you the password for this laptop. Which of the following actions should you take to resolve this issue and get past this password screen?
A. Remove the laptop's battery, wait a few minutes, reinsert the battery, and then power on the laptop
B. Disconnect the hard drive from the motherboard for a few minutes, reconnect it, and then power on the laptop
C. Remove the CMOS battery, wait a few minutes, reinsert the battery, then power on the laptop
D. Press and hold the power button down for a few minutes, then attempt to power on the laptop

Answer 1

Answer:
C is the answer!

Explanation:

A hard drive contains your operating system which can include your settings and preferences that you included in your device. But it mostly is a storage device so we know it WOULD NOT BE (B.

WOULD NOT BE D beacause powering it back on wouldnt do anything but bring you back to the start.

WOULD NOT BE A beacuse when taking out the battery then putting it back in would just be like turning it off then back on beacuse that just hold the power to a device.

IT WOULD BE C, C IS THE ANSWER beacuse a CMOS batttery contains the main system settings and  also contains information so i think C would be the best answer for this choice.

Hope this helps!
