I have a Toshiba Satellite S55t-B5233 laptop. Works fine but keeps losing the date and time when its off for more than a day or two. It's as if the CMOS battery has gone bad, but I cannot find any reference on the internet about the cmos battery location for this device. Opened it up and do not see anything that looks like a cmos battery. Help!

Try taking out (disconnecting ) the main battery, and then power flush the system. IIRC some Toshiba laptops have the CMOS integrated in the main battery.
