Is there really a market for modding a 7+ year old laptop? I know thinkpads used to be great (And some still are), but, I just don't get the point in trying to give more life to something so so old - most likely ~3rd-4th gen intel.
I'd be happy to buy a replacement battery for my X220 from a non-sketchy source if I knew it had new, matched cells and wasn't going to explode.
I left a good one in it while docked but unplugged, the dock apparently killed the battery.
I'm pondering whether changing the 16550 cells make senses
