X240 won't power up unless mains is connected? Battery appears to be working??? please help



I have a strange issue with my thinkpad.  My x240 won't boot from the battery.  

If the laptop is switched off completely it will only boot once the mains power has been connected.

Once started the mains power can be removed and it works fine.

You can restart, put to sleep, close the lid, and it all works and starts up again.

If you shut down it won't power up again until the mains power is connected, even with a fully charged battery.

Any ideas?

All help greatly appreciated.
