Where is the RTC Battery Located on Satellite S50Dt-B

I am getting the RTC Battery low message and have to set date and time. Can't find where this battery is on the mother board. Really need to find it.

 

Its a 2 pin connector near the WiFi card, the battery is tucked between the wifi card and the hinge.

Still can't see it. Removed the WiFi card, nothing in the area looks like a battery. See above link to picture of Mother Board.. Any other ideas? I actually rand Toshiba and their answer was "under the CPU fan", it wasn't there either..

Further to this, I am now thinking there is no RTC battery. The Toshiba I have has the main battery secured by two screws, so the cmos and rtc is probably kept alive by this main battery.

 

On that model there isn't an RTC battery, its the laptop battery that is also used as BIOS/RTC battery.

Unless it is soldered under the mobo, I tore a couple of those apart and there was no battery visible, and every time I removed the battery to take them apart they would say RTC battery low, but wouldn't show it again in subsequent boots with the battery plugged-in.
