Check to make sure the power cord is firmly in place in the power adapter. The power cord sometimes loses contact with the receptacle in the power adapter.

Remove the battery and the AC adapter (charger). Press and hold the power button for 3 - 4 seconds with these removed. Pop your battery back in, along with the AC adapter. If it still refuses to charge, you could be looking at a bad battery or possibly a bad charging circuit on the motherboard.

I took my x230 apart, checking the small yellow AC connector for the adapter, plugged in several times in confusion and looking bamboozled at the orange

battery (which is the original btw) LED.

How in god's name does one come to get to know something like that, which isn't even mentioned in the manual.

I'm a happy x230 customer but that lock is bizarre and just effin stupid

Live long and prosper,

Greetings from Germany

Usually this is due to bad charging circuit in Thinkpad.

If you have a meter, remove the battery and you will see a set of connector from Thinkpad to battery.

The first 2 slightly longer connector pins is Negative. The next 3, you should get 3.3v when power adapter is plugged. If one of them is missing, your battery would not charge.
