P40 yoga hangs when charger is removed

[sanjana8838]

My Lenovo P40yoga is a brand new laptop and whenever I remove the charger the screen seems to hang. Anything I must have done wrong while setting up? How do I fix this?

It may well be that the battery is not putting out enough power to run it correctly. If that is the case, the only fix is to replace the battery, or only run it while it is connected to the charger.
