Pay attention upgrading Lenovo T500/Radeon 3650 to W10
Upgrade works fine but finally the screen is black and still remaines black even trying everything! There is no chance for a downgrade.
In my case fortunately Teamviewer was installed and started. Remote downgrading was possible.
Today I tried upgrade again with result black screen like before. So I had to work from remote Laptop again. But now I could install the new driver and without restart the screen suddenly was visible!
It's resolved and I will post this in the other forum.
Thank you so much, Wagnard!
