There are usually three ways of proceeding, and it depends entirely on model and what is available to you:

  1. If your laptop has a manufacturer provided power utility, take a look in that for a calibrate button.

  2. If that fails, look in the BIOS for a calibrate button.

  3. If both of those fail, simply charge the battery to maximum and then go in to the BIOS and unplug. Do a full discharge and this should calibrate the battery. I always say do it in the BIOS as this makes sure there is nothing running/active that can be damaged by a forced shutdown.

You should probably disable any power settings that might hibernate/sleep the computer when battery-power drops below a certain level. – Nifle Feb 20 '11 at 10:56
@Nifle If you go into the BIOS, this isn't needed. – Nyuszika7H Mar 12 '11 at 11:06
