If your lucky the battery will be in a battery holder
but its possible they have used a battery that is soldered in
(to try to ensure you have them service your machine ???)
going by the bios date I don't expect the CMOS battery to be hidden in a DALLAS DS1287 or DS1387 real time clock IC like this
I expect its more likely to be either a CR2032 "coin cell" as found in many PC's
or for example a CR1/2 AA as used in a HASS SR100
