T430s ultrabay battery not charging stuck at 0%

I have a thinkpad t430s and I bought a new supposedly oem lenovo 43 ultrabay battery. When I insert the battery it is recognized that a battery was plugged in but it stays at 0%. I've tried all different combinations of reinserting it before and after reboots turning on and off the ultrabay in the bios. The CD / DVD ultrabay drive works fine, although since the connectors inside are totaly different I doubt that is relevant info.

What is the best way for me to figure out if the problem is this battery or the laptop? Or could it be a software issue...

any help would be hugely appreciated. One of the main reasons I acquired this laptop was the use of the ultrabay batteries.

Re: T430s ultrabay battery not charging stuck at 0%


Take a look at the webs above. They may help, but from what I learnt try this step and see if it work. Take main battery out, put ultrabay battery in and plug the laptop to a charger. It will detect it as only battery and should now charge it, connect the other one and should still work.


If not go to BIOS:  turn off (disable) BIOS -> I/O -> "Ultrabay CD/HDD


So if your main battery is not fully charged either, ur ultrabay will never be charged, unless u change it to main battery. Smiley Happy
