Where is the CMOS Battery located on a Lenovo P500?

I'm trying to clear my CMOS, but I can't seem to find the CMOS battery inside of this laptop.

Any help?

Its mostly on the motherboard and very easy to locate.
whatever the computer is.

Go into BIOS and Reset it. Seems a lot simpler solution.

It is probably on the other side, which is the side right under the keyboard and all that.
The image shown here is of the side that sits flat on the table (or any surface) when the Laptop is being used. The CMOS battery could be on the side opposite to this.
