My thinkpad (P51s, windows 10) crashed. Now when I start it up I see the lenovo splash screen that says to interupt normal startup, press enter. Then it will go to the boot menu (blue and get screen with two tabs, boot menu and app menu, under boot menu my options are windows boot manager and PCI Lan, under app menu my options are Diagnostic Splash Screen and Lenovo Diagnosics). When I select windows boot manager the screen refreshes. I have run the lenovo diagnostics (took about 10 hours) and everything passed. I have reset the computer and changed the bios boot order, no impact. I have tried to start up with it unplugged and with the external battery removed and both, no change. Every once in z while after testing it 50 or so times it will start windows and everything will work fine. When windows does start I have run all the windows and Lenovo updates. I have tried reimaging the computer, no change.

Just a guess, but I think your boot SSD is slow to respond to a power-up command. I would try turning off fast startup (control panel/power/change what power buttons do) I don't think it's likely to work, but it's free and easy. If you can borrow another drive, try that.
