I have an HP Stream 8 5901 Tablet (model K4F55UA#ABA), that is/was running Windows 10. OVER A YEAR ago, I tried to performed an update... either a firmware or Windows (don't remember what...ugh), but the update required a user confirmation on reboot. Unfortunately, the user interface drivers are apparently not loaded yet (touch screen or USB) and I have no ability to cancel or confirm the process. I can't even get the thing the reboot so I can try to enter the bios. I have tried all manner of USB devices (keyboard, mouse, boot disk). I've even let the batteries run out hoping re-powering would force a reboot... no luck.
If you can't see the picture, the message reads:
