I was updating EC for Battery Slice 27++ on T430 (28++ is official version for my thinkpad) - Ended up I needed to just update the bios version Make grabs from Lenovo to the latest version - almost followed Matthew Chapman's blog which would have been messy for me - ha! Can confirm battery slice (9-cell 27++) is charging on T430 now. - I learnt quite a lot.
