Battery Calibration - Sleep or Off

[coastertux]

In Apple's instructions for calibrating the battery they say that you can either turn the computer off or let it sleep for 5 hours or more. If I turn it off, can I re-charge immediatley or do I also need to wait 5 hours?

Calibrating your computer's battery

Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
Disconnect the power adapter with the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, you will see the low battery warning dialog on the screen.
Continue to keep your computer on until it goes to sleep. Save all your work and close all applications when the battery gets very low, before the computer goes to sleep.
Turn off the computer or allow it to sleep for five hours or more.
Connect the power adapter and leave it connected until the battery is fully charged again.

Either sleep or off is ok. What they want you to do is not use the computer for 5 hours, but it can be in sleep mode or off while it charges and then calibrates.

Side Note, don't forget to note the make and model and the OS version you have when you ask a question.
