"Hibernate" saves everything in memory to the hard drive, then shuts down the computer completely. "Standby", on the other hand, is basically a deep sleep mode, where all the processes are suspended and the computer is powered down, but not completely, as is the case with hibernation.

Standby mode is quicker to resume normal operation, but hibernation doesn't drain the battery as quickly as standby does.

However, this will be irrelevant when Vista is released, because M$ is creating a new power-down state that will combine elements of both hibernation and standby, and get rid of those as seperate entities.

Hmmm. Maybe I'll run some "full battery hibernation v.s. full battery Stand by" drain tests during a couple of nights and see what the real difference is.

Thanks for the info.

I'll post my findings to this thread to make it "Noob Search Worthy".

I'm pretty sure on hibernate your battery will last as long as it would if the computer was just sitting, unplugged and turned off. On standby it will last quite a while, but the computer is still 'on', to some extent. I'm pretty sure that on standby the hard drive will spin down, so that shouldn't be a worry.

I would suggest fully shutting down the laptop when your transporting it. Hybernate isn't much different then a full shutdown so there is no point in it. If your just walking away and leaving your laptop for a few hours then you can put it in standby or just leave it running.

It's exectly what it sounds, Standby mode is like "Standing By" therfore you stand in one place and don't move saving processing capability. Kinda like a blank screensaver.

Hibernate is when you go take a nice good nap. This you use if you are too lazy to shut down and constanly load windows or whatever applications are running. Just like a bear "hibernates". In thism ode everything pretty much is at a stand still except you memory. To be exect it rolls over where your memory left off. This can unfortunatly cause some apps to msifunctiosn but usually thats not the case.

hibernate: ram is saved to disk --> no power consumption at all

standby: everything but ram is shut down --> pc still needs a little power

standby is faster than hibernate, but you have too keep the battery attached and/or the ac pluged in.

I'll leave Hibernation enabled with the default shutdown occurring at 3% battery, and set it to Stand by when I close the lid.

Uhhhm, I'm probably a doofus for not knowing this, but how do you save everything in one felled swoop before putting it Stand by?

You don't need to save everything before hitting Standby or Hibernate. The whole point of those modes is to copy the entire working state of the machine to RAM or disk, then turn off the machine. (In Standby enough circuits are kept powered to keep the RAM alive, but that's it.)

Then, when you want to resume, the machine slurps that saved state back and just keeps going. If you were playing music in Winamp, it'll be in the same spot of the same song. Games resume right where you left off. Network connections, obviously, are disrupted somewhat.

Setting the machine to standby whenever you close the lid could be a nuisance -- what if you want to play music with the lid down, or keep a network connection alive while you carry the machine from one room to another? You can just manually standby whenever you need it.
