A couple thoughts. 1) The battery may simply be dead. AFAIUI, modern laptop batteries have internal circuits that disable the battery if they detect anything that could be dangerous. There may be a (Windows-only) utility that Lenovo offers to check this. 2) Have you upgraded the laptop's internals, or changed the power charger you use? I know that newer models of Thinkpads will refuse to charge if the charger can't put out enough power to do so. Lenovo makes chargers in many different wattage ratings. Is the one you're using rated to power an X220 in the configuration it's in? I.e. Models with faster CPUs/discrete graphics often require a higher wattage power supply than those without. 3) Power sockets get plugged and unplugged a lot, and tend to wear out over time. Could the socket itself be loose? Does "sysctl hw.sensors" show hw.sensors.acpiac0.indicator0 as being "on"? Does wiggling the power cable cause it to connect/disconnect? None of these are a definite answer, but hopefully one of them will help guide you to a solution to your problem. -- Bryan
