The CMOS battery is located on the motherboard, inside the computer.

YOu will have to dis assemble the laptop to get to it.

it aint easy, and you could break it.

In some models (its not published which ones) the CMOS battery is soldered to the board directly....making it VERY difficult to RESET the CMOS.

As you have to REMOVE the CMOS battery, and THEN you have to DRAIN the residual power by shorting out the battery terminals to each other.

That just means that you need to touch the positive terminal on the motherboard battery compartment, to the negative terminal on the motherboard battery compartment.

So the battery will be a button battery (CR2032, or CR2035) and the compartment the battery fits into has contacts (terminals) that TOUCH the battery to get the power.

its THOSE contacts that you need to touch together, WHILE the battery is OUT of the board.

make sure the MAIN battery is pulled, and the AC adpaotr is NOT plugged in.
