difference between hibernation and standby for T40P?

[llama_thumper]

was just wondering what the difference was - i assume there is some sort of power consumption on standy, whereas there is none on hibernation?
how long can the thinkpad be on standby?
are there any other differences?

Hibernation saves all your existing data in a file and then shuts the laptop down. Therefore no power is consumed, as the laptop is turned off. When you turn it back on, the hib. file is read and restores your session.

Standby saves everything to RAM. This means two things: First, your laptop has to power the RAM (and to an extent the processor), which means it consumes a little power. Second, and direct consequence of one, if you take the battery out / power off your laptop, you lose your data.

If a thinkpad is plugged in AC, it should not have a problem with standby, however it is not recommended to keep your laptop on standby more than a few days. If you want to keep it more, just hibernate it, since the boot process is very fast compared to normal shutdown and you keep your session intact.

Hope this helps
