Windows 10: Flickering and blinking laptop screen

If it doesn't hang waiting I would ignore. Otherwise, and I can't remember, did you disable fast startup in windows or disable hibernation as we went through fix process. If you did then you could turn back on. If you didn't then you've changed a BIOS setting.

See if you have one called FastBoot. There may also be another option to show this menu or not. Hence my previous comments, write down existing so you can reset. On my existing Asus I can take screen prints, handy when you are only in there every couple of years.

Really happy to hear its working and as a bonus you get a chance to explore your BIOS in detail.

I ran into a similar problem on my son's Dell XPS27 two nights ago, right after WUMT offered an Intel HD4600 driver update to me, and I installed it. All I had to do was use the "Roll Back Driver" button in Device Manager for that device (I show a screencap from my production desktop here, which has a GeForce 750 Ti instead):



When the driver is the cause, and you haven't cleaned out the predecessor driver, you can use this approach both expeditiously and effectively.

The home electric and other items would not affect the inverter for the LCD screen, since the battery acts like a UPS to help keep power spikes and the such from causing issues. The inverters for the screens have been known to fail, especially on off brand units that are not built to higher standards as known brand units.
