I have laptop Acer TravelMate P2 Core i5 7th Gen (Model TMP259-G2-MG).
My laptop automatically shut down sometime after 2 hours sometime after 3 hours or 30 mint.
Then i install new window 10 again and update all drive but still same issue.
But one thing i notice when i plugged in my charge this issue not appear. If i plugged in my charging for 6 hours also it not shut down.
