Start Windows Instantly (Almost)
You can optimize Vista all you want, possibly shaving 15 or 20 seconds off
your boot time (see the previous topic), or you can approach the problem
from a different angle.
All modern PCs support a Standby mode that allows you to shut down Windows
quickly, and more importantly, start it back up in only a few seconds.
Standby is a power-saving mode (known as the S3 sleep state) that maintains
power to your system memory and a few other components, while cutting
power to your hard disk, monitor, network adapters, and most of the
rest of the devices in your PC.
While it looks like it??™s turned off, a PC in Standby mode still uses some electricity.
If you remove the battery from your laptop or unplug your desktop
PC while it??™s in Standby mode, the power to your system memory will be
cut, and you will likely lose data (just as though you unplugged it while it
was still on).
The Hibernate mode (the S4 sleep state) solves the power-off problem by
storing an image of your RAM on your hard disk and then shutting down
completely. This means you can cut power to your desktop PC with a separate
power strip or remove the battery from your laptop, and still resume
your last Windows session in a fraction of the time it would take to start
Windows normally. The downside is that Hibernate takes a little longer to
shut down and start up than Standby, and you need a lot more free disk
space (at least as much as the amount of RAM in your PC).
