R40 Second Ultrabay Battery issues

Can someone enlighten me as to how this is supose to work? This is how it is working on my R40. Running on main battery w/ secondary battery installed in UltraBay. First (main battery) becomes depleted system goes into standby. Take it out of standby and it promptly drains the main battery and does not transfer to the second fully charged battery in the ultrabay. Restart and it attempts to run off the primary battery. The only way I can get the secondary battery to come online is to remove the first battery while the system is off then boot with the second battery.... not once I have that up I can't install the first battery or it will transfer to that one and shut down...

Is this the way it is supose to work?

Well, that is bizaar. My T4x laptops, that have the modular bay battery, depletes it first and then it automaticly switches to the primary battery.

Have you updated the power management drivers and utility from Lenovo yet?

Yes, all the drivers are 100% up to date. It starts out on the main battery, drains it then shuts off. I have to remove them ain battery to get it to use the ultrabay battery.
