G7 Randomly Reebots. Kernel-Power Event 41

No much to say actually. Laptop is brand new, I've had it for a month, since day one this has occured but didn't noticed until it got more frequent. What I have found that this happens when Laptop is unplugged. I went to Window 10 event viewer and found the reason is rebooting is "Event 41 - Kernel Power, The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." But that's all. I haven't tried anything to resolve this, no bios upgrading, no clean installation, etc. Tried to contact Dell, but as I am outside US they are trying to redirect me to other channels that I'm unable to reach.

Also I've got a blue screen saying "Stop Code: DPC_WATCHDOG_VIOLATION"

Thanks for all your time
