So, at step 3, how can you power the computer off if it´s in sleep mode?

I have experienced between 30 and 45 minutes of extra battery time after performing this. It is such a pain, I usually only do it just before a trip.

Jose, I look at it is 'preventative maintenance' so I'm not really seeing any battery improvement. With proper usage and calibration, I expect my battery to have an overall longer lifetime than if I didn't take care of it properly. Yes, you can calibrate the extended battery.

Don't forget to let it fully charge after plugging it back in.
