When someone give us a phone call on our 5G Cellular Laptop or when someone telephone us on our  5G Cellular Laptop , our 5G Cellular Laptop will show an  "incoming call"  together with a ringing tone , on the  15.6 inches  Touchscreen of the 5G Cellular Laptop  , just like our landline telephone , just like our 5G smartphone , regardless whether the 5G Cellular Laptop is in  LAPTOP MODE , or in TABLET MODE or in TENT MODE or in STAND MODE . The ringing tone will operate eventhough the 5G Cellular Laptop lid is closed .  This feature is very useful.  Because when we carry or lug our 5G Cellular Laptop in our backpack or when we carry our 5G Cellular Laptop with our hands ,  the lid is usually closed .
