This article provides information about What is BIOS STR (Suspend to RAM) S3.
STR S3 stands for Suspend to RAM (S3 state), a power-saving state in computers that puts the system into a low-power mode while preserving the session in the computer’s RAM. Here’s how it works:
-
Memory Retention: In S3, the CPU, hard drives, and most components are powered off, but the RAM remains powered to retain data, allowing a quick resume when you wake the system.
-
Power Efficiency: S3 uses very little power compared to an active state, making it ideal for conserving energy when you temporarily stop using your computer.
-
Quick Wake-Up: When you wake the system, the computer restores the session without needing to reboot. Resuming from S3 is faster than from hibernate (S4), where data is saved to the disk instead of RAM.
S3 is generally used by default in sleep or standby modes, allowing users to resume work efficiently without sacrificing power savings.
