Windows 7: Go into sleep mode or shutdown?

I like the modern Power Options which are perfected in Win7.

I can walk away from the PC without concern for whether I'm coming back in an hour or a week. If less than an hour, I just move the mouse and it wakes up from sleep. If longer it writes my work from RAM to HD and shuts down, but starts up twice as fast when I resume it later.

If there is a power failure while it's sleeping, my work is safe since it's already been written to HD when entering sleep thanks to Hybrid Sleep being enabled.

I still Shut Down when I know I'm done for the day, but otherwise I just walk away without having to think twice thanks to Win7 finally getting Power Options purrrfect.

Are you using S1?

I haven't checked. These same settings have worked fine on hundreds of installs over three years without ever having to change the BIOS settings. Troubleshooting almost always only requires updating the Display driver.

Global states

The ACPI specification defines the following four Global "Gx" states and six Sleep "Sx" states for an ACPI-compliant computer-system:
  • G0 (S0): Working. "Awaymode" is a subset of S0, where monitor is off but background tasks are running.
  • G1, Sleeping subdivides into the four states S1 through S4:
    • S1: All processor caches are flushed, and the CPU(s) stops executing instructions. Power to the CPU(s) and RAM is maintained; devices that do not indicate they must remain on may be powered down.
    • S2: CPU powered off. Dirty cache is flushed to RAM.
    • S3: Commonly referred to as Standby, sleep or Suspend to RAM. RAM remains powered
    • S4: Hibernation or Suspend to Disk. All content of main memory is saved to non-volatile memory such as a hard drive, and is powered down.
  • G2 (S5), Soft Off: G2/S5 is almost the same as G3 Mechanical Off, except that the PSU still supplies power, at a minimum, to the power button to allow return to S0. A full reboot is required. No previous content is retained. Other components may remain powered so the computer can "wake" on input from the keyboard, clock, modem, LAN, or USB device.
  • G3, Mechanical Off: The computer's power has been totally removed via a mechanical switch (as on the rear of a PSU). The power cord can be removed and the system is safe for dis-assembly (typically, only the real time clock continues to run - using its own small battery).
Furthermore, the specification defines a Legacy state: the state on an operating system which does not support ACPI. In this state, the hardware and power are not managed via ACPI, effectively disabling ACPI
I see it as for habitual, I may choose S1 (as Greg does). For temporary, S3 is preferable. (need you to shutdown when done working with it)
I use to shutdown it when leaving for office, leave the PSU less burdened though it takes only 5 watts in sleep states.
