laptop charging batery

Is there a program to watch the % while is charging my laptop?

cuz to know if it's finished I have to turn the laptop again and the light doesn't shut off so I'm asking like a cellphone thing,when you charge the cellphone and is finished says charge COMPLETE, but is there a program for the laptop for that?

The charging indicator LED should look different from when full charging and trickle charging.

no same colour :( so you don't know when is fully charged
