Disable "Blinking" Light When Powering Down Computer Into Sleep Mode

Hello.

So for the longest time ever, I customized a method to whenever I want to power down my computer and then start it back up again, it would reload everything that's already open. When I run this little custom "script", it enables Hibernate mode (where Windows creates an 8 GB hiberfil.sys file, taking 20 seconds or so, in the root of C:\, and the computer powers off). Then when I turn on the computer, it takes about 20 seconds to load up from the Hibernate state, and the hiberfil.sys file gets deleted once the computer reloads exactly where I left off, with all programs that are already open, which is really cool and convenient. I really love that little setup that I have, and the loading time doesn't bother me at all really.

But: I am aware that over a period of time, it is possible that an SSD drive may get damaged slowly whenever files are created and deleted and whatnot. So I looked online to see the method of setting the computer to go into Sleep mode. I found this:
"RUNDLL32.EXE powrprof.dll,SetSuspendState 0,1,0"
and tried it. The computer shuts off almost immediately (I am aware that it doesn't create a huge useless file on the drive, and everything is saved in the RAM), and once I turn it on, it loads up very quickly with everything that I left open. So this method is almost exactly like Hibernate, but more "efficient", obviously. My only issue is that once I put the computer to Sleep, the LED light on the Desktop case blinks every second or so. I sleep in the same room with the computer, and that blinking would obviously bother me so much when I want to sleep.

So I am asking for a method, within Windows, that I could set to when I put the computer to Sleep, it would power down, yet the LED light would turn off completely. And please, the suggestion of physically covering the LED light with some clothes or tape, is not a solution. I want an option that I can set within Windows which disables the blinking LED light.

Thank you so much!

Very unlikely to be possible unless you have a BIOS/UEFI option particular to your MBO.
It also acts as a sort of warning to dissuade you from pulling the power plug, for example.

This has been asked numerous times over the years - I assume you've done a general internet search already.

Or you could just put a notebook (paper sort!) or paper on top of it if facing up, or a book or other object against it, or arrange your furniture appropriately.

Alternatively, if you want a real project, design some hardware actuated by Windows to cover it...

dalchina: Yea, I did general research to figure out if it's possible to turn off the LED blinking while Sleeping, yet saw results with people physically altering their motherboard. I'm not going to take a risk to do that just for this little solution. But also, physically covering the LED / re-arranging furniture in the room, won't really work either. I saw one post where I can put the computer to sleep, and try unplugging the power (it apparently works with one person). Yet assuming that this works for my motherboard too, it would still be out of the picture, since I'd have to physically unplug the power cable from the wall. Too much of a hassle; I'm all about simplicity =)

hsehestedt: Okay thanks for that info. I really appreciate you opening my eyes to the name and process of this.
Yes, my drive should last a very long time according to that info. With a quick internet search of this main drive and TBW rating, it seems that this SSD (on which Windows is installed on) will last up to: 500 TBW (yay a big number!)
(So assuming that I hibernate the computer every day (which I don't) and that it takes 8 GB (which you are right, probably not as much as 8 GB), then let's try to calculate this extreme scenario.)

[Assuming that the hibernate file takes up 8 GB] AND [I hibernate the computer every day]:

• 1024 (GB in a TB) divided by 8 GB = 128 days to consume 1 TBW. (or in other words: 8 GB a day for 128 days = 1 TB).
• 128 days (aka 1 TBW) times 500 (to reach the max TBW) = 64,000 days (wow that's more than I expected before I started the calculation. Let's see how many years that is).
• 64,000 days divided by 365 (days in a year) = about 175 years?

...that's a weird number for years. I did the calculation correctly, right?


Well anyways, assuming that is true, then this drive should last for the rest of my life! Hahaha. The drive will probably cost like $2 when I'm in my 50s, if it would ever exist 2 decades later. Okay. But also, like you said, the computer most likely doesn't write that much space to the hibernate file, and I don't use Hibernate that frequently. Lately I've been using it much, but will probably be shutting down the computer, to turn it off, within the next week or so. Hence not a lot of space will be written on the drive, even when I'm using the computer doing intense work at certain moments, when downloading gigabytes of data at certain times. So the drive, technically, should last a long time.

Thanks for helping me figure out a rough estimate of this drive's lifetime.

hdmi: Thanks for the suggestion, but I'm not going to modify any hardware in the computer.

Thanks for all the info, everyone. I seem to be leaning towards just using my same method of Hibernating the computer, whenever needed, and not worry about it, nor have an issue with startup times, in comparison to waking up the computer from Sleep.

Thanks for the next replies.

I'm not too sure about physically covering that light, since it doesn't look too professional on the desktop case. I'll keep it in mind though, if I figure out a small technique to make it look professional, or purchase a small device that flips from top to bottom or something.
