Hi guys. There is an old laptop Lenovo ideapad 110-15ACL AMD A6-7310 APU with AMD Radeon R4 Graphics + discrete AMD Radeon R5 M430 2gb., RAM 8 Gb, ssd 240 Gb. Until 1903, all driver versions worked fine. After installing 1903, the laptop only works with the old v.21.19.512.0 (21.03.2017) drivers from the Lenovo website. But if I disable a discrete card in BIOS, then I can install any, even the newest driver. When installing any AMD Video driver, Win10 1903 is loading, but a black screen and an empty taskbar. If you install the old driver v.21.19.512.0 (21.03.2017) from the Lenovo website or turn off the discrete card, it works super. What could be the problem? Why do all new drivers work for 1809, but not for 1903? What could be the problem?
