This is an interesting problem that I've had since I purchased this computer from Ibuypower in 2014. I know the computer is a couple years old, it's out of all warranty. Sure, it would be easier to replace it or continue tolerating the problem. If it weren't for my curiosity.
Please read all the details. They're not embellished and they've been tested for frequency. Even if the problem is obvious. Every single time the screen display goes black, either during system boot, the startup of a large app, plugging or unplugging hdmi cords, or the computer going into sleep mode, my computer rolls a 70-80% chance of coming back with a white screen that may or may not display slight ghost images from 10 or 20 minutes previous. The computer is not frozen. It operates normally from behind the solid white display. Once I have a white screen, if I can perform some action like putting the computer to sleep again, then waking it, or if I can blindly run a large, graphics oriented application that normally causes the screen to black again, I have roughly a 33% chance of regaining normal display.
Alternatively, if I plug an hdmi cord into my laptop's hdmi out while the other end is connected to another display that has power (my laptop auto detects when an hdmi cord is inserted) the display will cycle and I will regain normal display function every single time. 100% success rate out of more than 100 trials. Should I remove the cord so that I needn't squat in front of my TV whilst I compute, then I roll the whitescreen dice again.
*Note: Simply using an F command to shut off my display and turn it back on has absolutely no effect. 0% probability of creating or removing the white screen effect.
Thanks very much for taking the time to read. It's really appreciated.
I'm just welcoming theories as to what it is.
