ThinkPad X1 Tablet (2nd Gen) - entering sleep mode unprompted

This tablet has successive episiodes where it enters sleep mode, without user action and when battery still has sufficient charge. Battery seems fine, and Power Options are set to 5% / Hibernate.

 

Can't seem to replicate the behaviour - but details as below. Does anyone have any ideas as to how to troubleshoot further?

 

Event viewer:

Event 524, Kernel-Power: 'Critical Battery Trigger Met'

Event 42, Kernel-Power: 'The system is entering sleep. Sleep Reason: Battery'

 

Battery report:

CYCLE COUNT: 29

 

Critical battery action:

On battery: Hibernate

Plugged in: 5%
