I have a Lenovo ThinkPad running Windows 10. Since yesterday, I've been having a problem that I haven't encountered since my laptop initially upgraded to Windows 10 (which I still swear to this day it did automatically without my permission). Whenever I try to boot up my computer, I just get a black screen. When I boot it up, I'm able to see the "Lenovo" window and also the Windows 10 splash screen. After that, I hear the boot up tone, but then all I get is a black screen. Every once in awhile, I'm able to see my cursor, but not always.
Before the computer upgraded to windows 10, I was having issues with the screen not working, so I purchased a whole new screen. After I installed it, I still had a black screen. Therefore, I did some research and just by chance I ran across someone online that had this same problem and they unplugged a yellow "backup" battery under the touchpad and when they plugged it back it, they got their screen back. I tried it and it worked too! I had no issues with the computer until the windows 10 upgrade. When the computer first upgraded to Windows 10, I didn't get an image, but if I put the computer to sleep and then work it up, I got an image again. This no longer works. I also tried unplugging the "backup" battery to see if that would fix it. No luck.
I have a feeling it has something to do with the display driver (especially since I can see the splash screen image), but I don't know what to do from here. Since I can't access my computer anymore, I don't know what to do to troubleshoot.
Any help to get my image back would be greatly appreciated.
