Cmos battery for fx6000-01e

[nanotech_2013]

Where exactly is the cmos battery for my fx6000-01e? I just unplugged the A/C to switch over to UPS and when i brought the system back the clock was set to 2008. Must need a new CMOS battery. My case cover is off and i'm looking straight at the motherboard and I don't recognize anything resembling a battery disc. Any recommendations on which replacement to select once i finally locate it? Thank you!

Usually the CMOS battery resembles a watch battery - round and flat. There should be a clip holding the battery in place. According to http://www.ehow.com/how_5558662_replace-gateway-cmos-battery.html the battery should be located to the lower left side of the CPU in most Gateway computers.
