I'm considering upgrading to a 970M (with the 940XM), but am hesitating because I worry that removing the power cable will crash the system. Can anyone with this configuration assure me that this will not happen? Alternatively, any suggestions on what throttle settings to make running on battery power viable? I am aware that battery life will be laughable, but this concern is more for transporting the m15x ≤5 minutes without AC power. Thanks.
