It seems a little odd that my computer has the same functions as a bear…sleep and hibernate, especially when those terms don’t translate very well technically. I mean, obviously my computer hasn’t crawled up in a cave somewhere for winter (well, I suppose it could do that to0) but will I lose data? Which one means I can get my computer up and running quickly? and why would I ever want my computer to sleep?
Sleep (Standby)
In a sleep state (standby), your display and hard disk turn off, and all open programs and files are saved in random access memory (RAM)—your computer’s temporary memory—rather than to the hard disk. Information stored in RAM is cleared when the computer turns off, so it’s a good idea to save your work before placing your system in standby mode. Otherwise, you may lose data if you lose power, you swap batteries, or your system crashes.
Sleep (standby) is particularly useful when you’re using your mobile PC intermittently during the day. For example, when driving between clients’ offices during the day, put your computer to sleep or on standby to maximize the life of your battery and maintain quick access to open programs, files, and documents. When you want to use your computer again, it wakes up quickly, and your desktop is restored exactly as you left it.
Hibernation
In hibernation, your computer saves everything to your hard disk and then shuts down. When you restart the computer, your desktop is restored exactly as you left it. Hibernation uses less power than the sleep state (standby), but it takes a bit longer to resume.
Hybrid Sleep
Hybrid sleep is a power-saving feature designed primarily for desktop computers. Hybrid sleep saves any open documents and programs to memory and to your hard disk drive, and then puts your computer into a low-power state.
Now I see…power saving tips! Now, if only I could function in a state of hybrid sleep.
