Why has my gpu suddenly dissapeared?

my gpu on my HP Pavilion Gaming Laptop 15-ec2xxx laptop suddenly dissapeared off task manager and there seems too be no trace of it ever even being there ive updated bios attempted downloading gpu drivers off the nvidia site but since it cant recognise the gpu being there it cant download i ran tests on the configuration menu and again no trace of the gpu its most likely a hardware issue but apparently this is a common issue with hps line of gaming laptops google said this could be becaise of a faulty bios update from hp but im not sure
