It... doesn't have one. It uses the main battery for keeping the clock. Crusty, i know. Most recent Asus laptops are built that way. On a lot of them there is a PCB footprint for a battery holder but it is not populated. I usually put them in if there is room for them as i don't have any use for the holders i scavenge off dead mobos.
BIOS settings on laptops have long been kept in the flash chip itself instead of CMOS memory, and Windows sets the clock on its own if it has an internet connection, so they thought they can save an extra few cents by removing the CMOS battery.

That is not a schematic but a board view (even better). Use Boardviewer: www.boardviewer.net
