Providing you know how... Open up your system and look for a battery it should be a shape similar to a penny or small coin and will have plus and minus on the sides , remove this and wait for 1 minute then put it back in and boot up again ... Another option is see if you have a reset jumper at all in your system it may be in the documentation.
Removing the CMOS battery is the best way just make sure to unplug the ac adapter and remover the battery with every power source removed hold down th power button for 30 seconds then reassemble everything and you should be good to go..
