I purchased a replacement battery for my 6th gen ThinkPad X1 Carbon. The old battery’s life was down to only lasting about an hour and would shut off without giving me any warning. Swapping the battery was easy, but the new one didn’t work at all. The laptop complained that there was a battery problem and it refused to charge. I tried removing and reseating it, upgrading drivers, etc. Nothing helped. I’m back to the old battery now. Is there anything else I can try before I return the battery? Could it just be this replacement that is bad and I should get another one, or is there some reason why no replacement battery will work?
