Update October 7, 2021 = A DELL-Cares agent setup service.
Hello everyone i have just purchased new a G7 7500. Since the 1st day the screen for no reason goes black. This is happening while i am in the internet browser or using outlook. It can happen in 5min, in 1h and so on. Its not standard. I have tried to disable Intel GPU which seems to solve the problem but then i got lagging while using MS Office programs. I re enabled Intel GPU, lag disappeared but then black screen happens again. I have searched internet and found that using Ctrl Shift Win B screen comes alive again. I have also tried to disable Panel Self Refresh through Intel Graphics Command Center, found it via youtube by dell but still no luck. Any ideas?  I have tried dell Nvidia gpu drivers, and also Nvidia drivers using GeForce Experience. Still no luck. I have seen another thread where the guy had his laptop replaced.
