LED screens are still subject to burn in. I noticed this on one of our TVs. We were watching a lot of SD content before finally getting an HD box from the cable company. We were also watching a lot of old movies in SD. A line developed on both sides of the screen that was noticeable at the margins of the SD image, apparent when we switched over the mostly HD content. It eventually disappeared.

Myy most annoying problem with Win 10 is that after a an inactive period the next update was substantial and messed up Microsoft Edge...it just wouldn't work no matter what fixes I tried even after a year. Luckily I had a Chrome browser so I still had Internet access.

A few months ago I switched ISP to Centurylink: presto! suddenly Edge was working again. Alas two days later I installed the latest Windows update, and BAM, Edge stopped functioniing again. I've given up on using Edge.

Plasma, LCD and OLED displays

A nearly two-year-old LCD television showing extreme burn-in of CNN's circa 2008 digital on-screen graphic; this television is in a McDonald's restaurant where CNN is permanently tuned in and displayed throughout the business day.

Burn-in on a plasma screen at Dallas Fort-Worth airport
Plasma displays were at one time highly susceptible to burn-in, while LCD-type displays are generally not affected.[1] The wide variation in luminance degradation with RGB-based OLED [2] will cause noticeable color drift over time (where one of the red-green-blue colors becomes more prominent).

In the case of LCDs, the mechanics of burn-in are different than plasma and OLED, which develop burn-in from luminance degradation of the light-emitting pixels. For LCDs, burn-in develops in some cases because pixels permanently lose their ability to return to their relaxed state after a continued static use profile. In most typical usage profiles, this image persistence in LCD is only transient.

Both plasma-type and LCD-type displays exhibit a similar phenomenon called transient image persistence, which is similar to screen burn but is not permanent. In the case of plasma-type displays, transient image persistence is caused by charge build-up in the pixel cells (not cumulative luminance degradation as with burn-in), which can be seen sometimes when a bright image that was set against a dark background is replaced by a dark background only; this image retention is usually released once a typical-brightness image is displayed and does not inhibit the display's typical viewing image quality.

The third update was an emergency update, probably an example of Sevareid's Law ("The chief cause of problems is solutions" - Erik Sevareid, 1970).

Jeez! You guys sound lime you are having all the issues that Linux was accused of for years. When I do updates on my Linux system (I get to choose which updates are installed, no longer an option in windows)my system runs the updates and at the same time removes any outdated files from my system. Oh and when I run updates all my free software gets updated too, all at the same time. And I rarely have to restart unless I change kernel versions.

Several days ago my building had a total power outage, CPS was not supplying power to the building. Yes, I do have solar power BUT, I was told that when the power goes off line, the power from the solar power is blocked from the power grid as a safety measure by the power company. It was daylight (mid morning).

Before I could disconnect the modern Dell from the power supply, the power came on. I was not worried as the building is surge protected. So the Dell PC was in sleep mode and I was able to open it and use the computer as if nothing had happened. I have an older Compact computer that was also in sleep ,ode. When I checked it and it had gone off line and needed a reboot. There was nothing wrong with this computer after the reboot.

I was truly amazed that with no power to the building that the newer Dell was in sleep mode and needed no rebooting.

"Hibernate" means the computer shuts off completely, after saving its running state as a file, which then returns Windows to where it was before putting it into hibernation.

If your computer really is going fully into hibernation (you have to press the power button to turn it back on, and it boots completely from scratch), what you are seeing is a USB port that is still powered even when the computer is turned off. Some computers have this, maybe as a setting you enable in the BIOS. It lets you charge something plugged into that port even with computer turned off.

Try plugging the keyboard into different USB ports to see if any of them let the keyboard lights go off with the computer in hibernation (or shut down, which is the same thing power-wise).

It's also possible that your computer is not going into hibernation as you're telling it to do, but only going to sleep. But that's a whole different ballgame to troubleshoot.
