This is an issue that I've seen with a number of ThinkPad laptop models, but seems to be more common with the 12 inch X240 and X250.

If a is competely unresponsive, no power indication or anything, put a bent paperclip in the pin hole on the bottom of the laptop and hold down the hidden reset button for about 25 seconds.

That often brings them back to life.
