You can hack the bios to remove the DRM and use 2012 aftermarket batteries, or replace the cells. I dumped my x230, not worth the horribly priced aftermarket (if you break your screen it’s almost as expensive as another laptop and you’ll need to repair it). I love my newer x250 with no DRM for WiFi, 2x SSD slots, cheap batteries that can hotswap, cheaper 1080p IPS replacement screens, and 11hr+ battery life. The x230 already lost the classic keyboard, the new one is fine, and the speakers are retardedly still on the bottom but it’s much louder.
