After upgrading my laptop to windows 10 Enterprise everything worked fine. My laptop was on AC power all the time during the upgrade from windows 7 to windows 10. Everything went smooth just like I experienced on my desktops. My login screen appeared and I could use my normal cooperate credentials after about 4 minutes my screen went black but my laptop remained active.
What now, first thing I learned with windows is to reboot. So use ÿ + R to get the run menu and type “shutdown /s /f” and my machine turned off. After a 30 second wait I rebooted and was excited to see that the bios screen was showing and then the windows start screen and then … . .. Black, black again when I was supposed to see the login screen and the laptop still running.
Long story short, after searching online I only found examples of machines that turned off entirely or where a cursor was still showing. But when I picked up my laptop to go to a monitor on my desktop machine suddenly everything worked again. What happened, I unplugged the power cord and I was on battery power. When I plugged in my AC power again everything turned black. After that I tried a few thing but the silver bullet was to change the brightness setting for AC power, just put it on 99% instead of 100% and everything worked fine.
Oh well, I had an interesting evening uncovering this mystery maybe this blog can save someone that time.
