HP Pavillion CMOS battery... where the heck is it?

[sticks57]

I have a HP Pavillion dv5000 and would like to replace the cmos battery due to charging issues. I can't find the darn thing. I removed the keyboard and the wifi card and NO battery. I removed the ram sticks also to see and still no battery. Any help would be greatly appreciated. Seems easy but you try lookin in this machine lol
