Two weeks into this. Hoping to trade info with others currently suffering this.
This is a problem which goes back on various brands to the introduction of win 10. If the display ever shuts down for sleep (closing the lid, going into sleep mode, or for any other reason such as selecting only an external monitor) it won’t come back on. The only way to get the display running again is to restart the computer.
This problem is especially hard to research because it is usually diagnosed (Misdiagnosed?) as a power problem or a sleep problem. Every single official troubleshooting session starts with the power options in windows. These never fix it. Then updating all drivers, again nope. Updating the Intel iris driver specifically. Nope. Then paper-clip reset and bios reset. Nope. Then windows updates. Nope. Then windows reset. Nope. Disabling fast start. Nope. Changing the “what closing the lid does” settings. Nope. Changing the “what the power button does” settings. Nope.
Some intrepid souls get into video driver backdating. I tried this, but never successfully got an older driver to install, They said they were incompatible and auto-exited.
Right now I’m using the machine on an external monitor, which works fine - so now I have a desktop. Well, I already had one of those, a better one. While running on the external monitor, both screens are fine until the laptop goes to sleep, or I close the lid, then the built-in display won’t come back on, and display properties says “display 1 is not active”.
So, I guess the only option is to send it in. Any advice appreciated.
