Will do but I thought to follow through for being the same subject.
True, the rule is one question warrants one subject, and no more than one, this forum with >1356872 (one point three million!) posts is cluttered up enough already.

So duplicates will be deleted without warning, or hesitation.
I will only do a quick judgment with copy can most likely be missed the best , but I'm only human, and unless I doubt my decision enough to move the post to a user unreadable place, (which is taxing the patience of other moderators, so it happens *very* seldom) deleted copies cannot be recovered.

I have realy 1 task for my raspberries developments - to show video from digital camera on screen. Nothing more. I have about 20rasps + 20 PSU's.
I dont wanna see on screen this sign "under voltage detected" , turned wifi, bluetooth off. Added string to "config.txt" - yellow build to the right up corner - gone.

How to remove under voltage on screen sign? annoying.
I know, im under voltaged (2100ma) - but thats enough for my tasks, i can even underclock CPU. But i think it wount help with this sign coming to console screen.

how to remove it?
Raspi is custom, thats why im kinda at a loss about "we have no function to remove it, its an smoke detector!" - ok, for everyone its ok. For me - i need this option.

Create a file called /etc/modprobe.d/raspberrypi_hwmon.conf with "blacklist raspberrypi_hwmon" inside and it won't load the kernel module that monitors for undervoltage.

The proper and recommended solution is to get a better power supply. (and sometimes the cable between power supply and Pi)

Don't just sweep the dirt under the rug - just because you can't see it doesn't mean it isn't there and isn't a problem.

Or use a Pi computer with lower power requirements.

Why not use a Pi2 (or perhaps a Pi Zero) instead?
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?

THANX ! a lot !

Changing to other computer is't an option when you already have 20pcs.
I made downclock.
