Yup, The CMOS battery on this model is on the power supply board. And the only way to fix it is to replace BOTH the M/B and the power supply board. I know this from sad experience.!
Luckily for me, my employer has service agreements with our suppliers, so they have had to bear the cost of the 4 x M/B & PSB replacements I have had to endure so far.
Apparently this modelwas not desgined or engineered by Toshiba themselves, but by an external supplier. I hear that this company no longer has any contracts with Toshiba anymore!
