Acer Nitro VN7-592G-747C randomly reboots when on battery

Hi,

My 3 month old Acer VN7-592G-747C notebook running Windows 10 randomly reboots from time to time.

I have only recently experienced it but I have not installed any new drivers in the recent past. I am not stating this as a fact but I assume that the reason why I only now (after 3 months of using the notebook) I came across this issue is that until now the notebook was always plugged in.

When it's on battery what happens is that Windows loads while I do regular tasks (nothing demanding, web browsing, opening Word, etc.) after a few minutes it reboots with no advance warning of any kind.
