If the upgrade process is allowed to continue, the upgrade will complete but you wouldn't have any way of knowing this. But when the first 1/3 of the process, downloading Windows 10, is complete, the screen goes blank, and nothing can be seen or followed afterwards. When the Windows 10 upgrade process gets to the screen where it is actually installing Windows 10, this is the screen with the circular progress indicator that pulses, the notebook screen display is still working.

After installing the A11 version of the bios, the computer display on the notebook screen worked without any other changes. The latest version of the bios for this computer is A11. As it turns out, Windows 10 loads the correct and latest driver for the Intel HD Graphics 3000 GPU, but if the Vostro 3550 has a bios that is not the latest available, the display driver will not drive the laptop screen. The issue with the Vostro 3550 was rather different and a little harder to fix. After the driver was downloaded, installed, and updated the video worked flawlessly. Dell has not provided a video driver for the 1720, but Nvidia has a Windows 10 driver that includes the GEForce 9600M GS as well as a slew of other versions, which can be downloaded directly from the Nvidia site. When the upgrade to Windows 10 completed, there was no driver found for the display, and Windows used the generic Microsoft video driver at a maximum of 1024 x 768 resolution. The Vostro 1720 has the Nvidia GEForce 9600M GS notebook GPU. Both had video driver issues, and I want to update the post for anyone who might be looking for information on these two computer models. I upgraded both Vostro notebooks this weekend. Upgrade advice for two Dell Vostro Laptops, 17
