I have Asus tuf b550m motherboard its cmos battery is dying in few days what is the problem is it because of motherboard or something else.
Depends what is shorted. If it’s an LED then it could work for weeks. If it’s a MOSFET or something then maybe a few minutes.If it takes a few days...it is not a short.
If it was a short it would die instantly.
If it is dying in a few days I would think it would have to be the motherboard and possibly some sort of current leak.
However I find it odd. It's not something I normally come across.
Any way to check that ? like with multimeterSounds like a short on the motherboard.
If you had about 50 hours to spare and the worlds steadiest hands, sure.Any way to check that ? like with multimeter
No.Depends what is shorted. If it’s an LED then it could work for weeks. If it’s a MOSFET or something then maybe a few minutes.
No.
A short will drain the battery almost instantly.
If an LED is truly shorted it will also drain the battery almost instantly.
Maybe.Any way to check that ? like with multimeter
The current involved in a "current leak" is usually orders or magnitude smaller than the current involved in a "short".can you describe what a “current leak” is without using the word “short”?
What is a current leak though? How would one occur?The current involved in a "current leak" is usually orders or magnitude smaller than the current involved in a "short".
Think of a current leak as "slow".What is a current leak though? How would one occur?
The only way for one to occur, to my (electronic engineering qualified) mind, is for there to be a short, somewhere in the curcuit.
And equally important to disconnect power and remove the PSU connections to the motherboard. Probably also remove USB devices....
I would set the multimeter to resistance and take the battery out and measure across the battery terminals.
It's important to use the correct polarity on the meter.

Terminology is funny...a resistive short wouldn't be fast, but you call it a 'leak', which I never heard used in this context in any of my technical schooling. It was always called a resistive short....
Shorts are "fast".

^^^^Agree.And equally important to disconnect power and remove the PSU connections to the motherboard. Probably also remove USB devices.
This is mainly to be safe and avoid possibility of spurious readings.
"resistive short" isn't a term I come across and I've been an EE for 40 years.Terminology is funny...a resistive short wouldn't be fast, but you call it a 'leak', which I never heard used in this context any of my tech schooling. It was always called a resistive short.
LOL...and we used it extensively in my EE schooling as well as tech school training and my job...funny."resistive short" isn't a term I come across and I've been an EE for 40 years.
I also did not come across the term "resistive short" while obtaining my BSEE or BSPhysics.
I think it is a confusing term.
It uses two words that basically mean the opposite of each other.
Maybe you had an instructor that like that term.LOL...and we used it extensively in my EE schooling as well as tech school training and my job...funny.
Well, have a good one. Maybe you should write a book to standardize it to your liking.
I think the difference is in the context of reference...Maybe you had an instructor that like that term.
In the real world automotive industry, on schematics and prints that specification is almost always referred to as the "leakage current specification".
The terms leakage and leakage current are used extensively in many technical documents throughout the industry.
The hipot industry.....which specializes in this...also refers to it as leakage and leakage current.
The term "resistive short" is extremely rare.

Very possible..I've never 'earthed' a darn thing in my life for instance (except maybe my face sliding into home plate in 6th grade). But they do that all the time in england. I ground myself before picking up a microprocessor, though, and would check facility grounds on a daily basis in the test labs.Could it be a matter of 'american english' versus 'english english' versus 'australian english' versus 'rest of the world english' ?? 😳
