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?

Hi Chris

I don't have a straight solution for you but can tell you that the way yours works isn't how it is supposed to ( I gathered you assumed this also). On my r40 the second battery (ultra bay (FRU P/N 02K6817) discharges first and then the main battery discharges automatically.

It sounds like you may have a IRQ conflict but that is a guess. Some things to try;

1. In the Thinkpad Configuration Screen is there a green dot against the device bay and power management? You may need to stop services of another feature to free up an IRQ. Interestingly on mine the PCMCIA card slot serice is disabled and when I try and activate it it asks me to stop the "Microsoft ACPI Compliant control method battery" service.

2. can you see both batteries when you click on the status tab in battery information in the Power Management menu of the Thinkpad configuration screen?

3. Update all drivers etc using the Lenovo software installer.

Hope this helps

Peter

It should work in a fashion to keep your main battery charged. Your secondary battery should deplete first, then your primary battery.

Your primary battery should charge first, then secondary.

pjm suggested running the software installer, and that's what I would suggest also, in particular update your bios and embedded controller.

Everything is up to date. No conflicts, but there are a few things using the same IRQ. No way to change it.

Both the windows battery indicator and the Maxamizer can see two batteries. Its just not going to the second one until I remove the first battery.
