  4. (d) Reducing the maximum processor state (clock speed/frequency) to cap the peak computational capacity and thermal output
Answer & solution

Answer: (d) Reducing the maximum processor state (clock speed/frequency) to cap the peak computational capacity and thermal output

Windows Power Saver Plan - Energy Conservation Mechanism
Power Saver plan primarily usesCPU throttlingto reduce energy consumption.
Key Technical Mechanism:
Reducesmaximum processor state(clock speed/frequency)
Typically caps CPU at 50-70% of maximum frequency
Lower frequency = Lower voltage = Reduced power consumption
Why other options are incorrect:
Option 1: GPU is never fully disabled, only optimized
Option 2: Spin-down time adjustment is minor, not primary mechanism
Option 3: Cache flushing would decrease performance without significant power savings
Answer: Option 4 → Reducing the maximum processor state (clock speed/frequency) to cap the peak computational capacity and thermal output

  1. (a) Shut Down, because it is the only way to achieve zero power consumption.
  2. (b) Hibernate, because it saves the entire system state to the hard disk and powers down completely.
  3. (c) Sleep (Standby), because it maintains the session in RAM for a very quick resume.
  4. (d) Hybrid Sleep, because it uses both RAM and the hard drive to store the session.

Answer: (b) Hibernate, because it saves the entire system state to the hard disk and powers down completely.

Requirement: Zero battery consumption + Quick resume with all work intact
Power Modes Comparison:
Sleep: Keeps session in RAM, uses minimal power (not zero)
Hibernate: Saves RAM to disk, powers off completely (zero power)
Shut Down: Zero power but loses all open applications/files
Hybrid Sleep: Uses some power to maintain RAM state
Analysis:
Hibernate writes entire RAM contents to hiberfil.sys on disk
System powers down completely → Zero battery drain
On resume: Restores exact session from disk
