the battery of my laptop last a short time. but it looks that has energy, is it worth to reprogram, i heard it takes a lot time... the battery is two years old not heavy used

Reprogram? dont know what you mean by that, but the easiest way to get a battery back to decent working order is to let it run dry and fully charge it a few times, sometimes known as reconditioning.

Sorry, correction. i ment battery calibration. does it have anything to do with. it says it takes hours to calibrate.

Cant say ive ever heard of calibrating a battery its not the kind of thing that needs calibrating, takes a while to recondition a battery but it doesnt require input from you you just leave it running then when it dies stick the power in.
