For the last 7-10 days, when I start my desktop computer and return to sign in, the P191w power light is amber and blinking. It is also ignoring the power button. It took about 3 minutes to recover so I could sign in and use the computer.
Before this, it was usually amber but not blinking. Moving the mouse was enough to turn it blue and show what the desktop computer was displaying.
In fact, when I signed on the last time, I did ctl-alt-delete (which my desktop computer has been requiring for several months now) and typed in my password without seeing the screen and in a few moments the second monitor came up and showed its screen. I was able to open programs that open on the P191W and then move them to the second monitor without seeing them. Whatever is happening, the computer itself is working.
Other threads discussing this for other equipment talks about battery problems, but there are no batteries in the relevant sense in my desktop computer (I suppose there is a small battery for the clock, but perhaps not). Certainly the display does not depend on the computer for power; it draws power from the standard house wiring.
I would like a solution to this problem, if one is known. If none is known, I would like to be told that explicitly.
I am using Windows 10 and I keep it up-to-date. Given the timing, it is possible that a recent Microsoft update is doing this. The P191W is connected via DVI, as the desktop computer requires that for the primary monitor.
