windows 10 - Monitor will not stay off


I am having this issue where the monitor will not turn off even though Windows power options are configured for it to turn off after a specified period of time.


In testing, I configured the timeout to 1 minute and waited for the monitor to turn off. The monitor will look like it will turn off, but it turns back on after a few seconds! I also tried third party software to turn off the monitor like nircmd and turn off monitor, but both of these exibited the same behavior. I have also tried running nircmd in safe mode, but once again, the monitor flashes off then on.


In an attempt to diagnose this, I made sure to unplug everything from the PC except for the power and display cable, however, the same thing occurred. Additionally, I have disabled wake timers and wake on lan. There are no game controllers connected the the PC as well.


This issue is extremely puzzling. Everything that I have tried will not solve the problem.


This PC is an HP Compaq 6200 running Windows 10 LTSB 2016.



Answer



After much trial and error by removing and stopping services, I was finally able to learn that the service causing the issue was the "Power" service by Microsoft. This, however, is a core service that runs as part of Windows. Without it, power plans and automatic monitor sleeping would not work. However, the monitor will still turn off manually by using nircmd.


Using dism and sfc /scannow, did not fix the issue with the Windows installation. The method that was able to fix the issue was an in-place upgrade using the original Windows ISO. This rewrote the Windows files while still leaving the applications and data intact.


EDIT: Upon reinstalling Windows and reconfiguring my settings, I noticed that this issue was once again occurring leading me to believe it was a setting that I changed. After some thought, I was able to discover that the real issue was due to the ForceAutoLogon setting in the registry I had applied. This prevents the monitor from turning off.

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
