ThinkPad X240 - Removal steps of the battery pack

As we know, ThinkPad X240 comes with dual-battery, an internal and an external one. And of course that we can replace the external one without power off the system. But on a bad day in the future, the internal one doesn't want to work and we need to have a replacement. Following step by step instructions can help you a bit.

First of all, read carefully below notices:
Important notices for replacing a battery pack:
This system supports only batteries specially designed for this specific system and manufactured by Lenovo or an authorized builder. The system does not support unauthorized batteries or batteries designed for other systems. If an unauthorized battery or a battery designed for another system is installed, the system will not charge. Attention: Lenovo has no responsibility for the performance or safety of unauthorized batteries, and provides no warranties for failures or damage arising out of their use. 
The Lenovo Solution Center program provides an automatic battery diagnostic test that determines if the battery pack is defective. A battery pack FRU should not be replaced unless this diagnostic test shows that the battery is defective. The only exception to this is if the battery pack is physically damaged or a customer is reporting a possible safety issue. If the Lenovo Solution Center program is not installed in the computer, the customer should download this program before a non-physically damaged battery pack is replaced. Note that a physically damaged battery pack is not covered by the warranty.

Use only the authorized battery specified for your computer. Any other battery could ignite or explode.
Then, remove the external battery:
