Black screen after Windows 10 upgrade on Lenovo Thinkpad SL510
I am working on a Lenovo Thinkpad SL510 that I can't get to upgrade to Windows 10 properly. It had Windows 7 Home Premium x64 on it. It goes through the upgrade process as expected but on the last boot it has a problem. I see the Windows logo and the circling dots, but then the screen goes blank. I don't even see a mouse cursor. Eventually I hear the chime where it is at the login screen, but there is nothing on the display. I've repeated this a few times (after reverting to Windows 7) several times.
I've tried the following with no significant changes:
I installed VNC (while in Win 7) and connected to the computer. It connects but the screen is blank in VNC also.
I disabled all non-Microsoft services as well as all startup programs (while in Win 7) before the upgrade.
I connected a monitor to the VGA port. It has the same image as the LCD and then goes blank at the same time.
I checked the BIOS settings for the Display. My choices were LCD, VGA, and HDMI. I tried the first two but not the third.
I set up a boot menu (while in Win 7) to include Safe Mode. That isn't invoked in Windows 10. I tried doing this again from a Win 10 installation disk but I still don't get the boot menu. I may not have gotten it correct in Win 10.
Once it was done booting up I hit the space bar and then Enter.
Once it was done booting up I hit Windows-P UpArrow twice.
Once it was done booting up I hit Windows-P DownArrow twice.
My presumption is that it is loading a video driver that doesn't actually work with the Intel Integrated graphics. I could likely fix this if I could boot in Safe Mode, but don't see how I can do that. It's not an option when booting from a boot disk and I can't get into Windows 10 to enable it any other way of which I'm aware.
I did some searching for how I could edit the registry to change the video adapter but wasn't successful at finding the appropriate registry key.
If I had a USB-VGA adapter, I'd try it, but I don't have one at the moment.
Does anyone have any suggestions as to how to proceed from here?

Your VNC idea should be followed, but instead, use RDP. VNC displays the actual session as you see it on screen, while RDP does not. If that does not change anything, update the video driver before upgrading. You also should make sure to use version 1511 of the setup.
Might try booting into safe mode. F8 during the post process should then give you options on how you would like the system to boot. Safe Mode with networking is my default choice.

@kstec: I've never been able to get F8 to work with Windows 10 and have found it VERY difficult to do it with Windows 8. Are there any tricks you can offer?
Guess I have not tried to start in windows 10 safe mode using F8, does not look like it works as it did on Windows 7. I just tried a Windows 10 laptop with no success.
I did find this article, looks like you may need to boot from a recovery drive?

Most obviously, the four don't work if the OS does not show.
So try option three from here: http://www.tenforums.com/tutorials/2304-safe-mode-start-windows-10-a.html and use the command prompt at setup booting as shown here: http://www.tenforums.com/tutorials/2880-command-prompt-boot-open-windows-10-a.html

@McKnife:
I tried RDP but this is Home Premium, not Pro, so it isn't there. Remote Assistance requires too much interaction from the host end to be able to use it.
I'm running sfc /scannow to see that I'm in reasonable shape before upgrading (again!). I'll check the video driver in 7 but I'm presuming it gets replaced in the upgrade.
I have been getting the Windows 10 through Windows Update. I'm assuming that it's the latest but certainly don't know that. The install.esd shows that it was created on 11/6/15 and was modified yesterday. The most recent of the other files have dates of 10/29/15.
I'm running the Media Creation Tool now to see if that gives me a newer version.
I tried setting up the boot menu with bcdedit after the upgrade (the one from 7 didn't carry over) but never got the menu to come up. I may try that again.

" I'll check the video driver in 7 but I'm presuming it gets replaced in the upgrade." - I agree, but nevertheless we experienced different results once. Yes, the Media Creation Tool should be tried, good luck.

I was unable to successfully complete the upgrade to Windows 10.
Laptops Notebooks
A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
