Unusual Power Drain When System Is Idle

I have noticed an unusual power drain on my system even when it is idle, with the battery percentage decreasing significantly without any active tasks or background processes running. Despite ensuring that all unnecessary programs are closed and performing regular system maintenance, the power consumption remains abnormally high during idle periods, leading to faster battery depletion than expected. This issue is concerning because it affects the overall battery life and makes me worry about potential underlying hardware or software problems that could be causing the excessive power drain. I am seeking advice from the community to help identify the possible causes of this unusual power consumption and to find effective solutions to improve the system’s power efficiency when it is not in use.
