how to find short circuit in laptop motherboard

[@donhjoe2162]

I have started checking and fixing computer mainboards and your tricks and tips are very useful. Thank you friend.

[@Shawdow194]

Thank you very much! Very informative, helped me diagnose which area and find out that it is an unrepairable motherboard

[@tahayt6142]

Yo bro I have a hp laptop that when I try to turn it on with the power switch the led turns on then off super fast and then nothing happens I think it's some sort of short but the charger led stays on I'm not sure what the problem is?

[@teachyourself6839]

U try on laptop without hdd and remove battery and on with charrger

[@krakadoros8605]

I want to use your method, but I do not want to do it automatically. I want to understand what I am doing, and why am i doing, so if you please, tell me. When, with your Ohm meter, connecting to the right side of the first power inductor (the coil) you receiving an indication of zero, you say that there is no short. As far as I know, when between to points or components there is no resistance, this means that these two points or components are not communicate between each other. So why, if the right side of the coil do not connect with the ground, this means that there is no short ? On the other side (the left side of the coil) there is an indication of 0.001 Ω which is probably near zero, and it is also means that there is not connection. But you said that there is a short. On the rest of coils, you received a indication of normal resistance (a few Ω), that means that there is a connection between these coils and the ground, and the conclusion is that there is not a short in both sides of the coils. And something else. When you saying that there is not short from this side of the coil what exactly do you mean ? Is there an area on the motherboard on this side that contains a shorted component ? And what are the limits of this area ? Thanks

[@nessim.liamani]

thanks. Sometimes, those coils are "shorted" when they are close to a CPU and GPU and the short disapear when we remove the CPU for instance. How do you explain and what to do if the CPU/GPU is soldered?

[@cool-ice976]

Good video its same for all pcb???

Hi, which career or online course do you recommend me to be able to diagnose shorts on electronic boards and circuits? Thanks in advance

[@teachyourself6839]

Every channel give u some idea but they dosent give u all thing in future i will try to make corse about that

[@hippopotamus86]

Quite hard to test for shorts this way.

[@joeycarr1398]

"But if you learn that method perfectly you will make lots of money", I was told by an experienced trouble shooter.

[@rudysmd7350]

Teach us more about finding short circuit please

[@VYJ-7]

Do you know a book on this issue to recomend?

[@teachyourself6839]

Book can give 25 % from knowledge but actual training can give real things

[@NOROKdsbm]

Thank you for this guide. So what is the solution for this?

[@wizaaa]

Buy a new one

[@blacksunyanasworld4688]

What to set in my digital meter to find short circuit? What did u use? Thanks

[@josepeixoto3384]

@How Not To with a 9 volt battery in the meter, in ohms mode you risk burning lots of things,no? cpu runs at around 1 volt,no? thanks you need DIODE mode...

[@josepeixoto3384]

@How Not To get ANOTHER METER and measure the VOLTS on the probes of the first multimeter in BOTH cases; you´ll see the DANGER of the high voltage there,for a CPU that works off 1 Volt only , me thinks *"the chief has spokin"*

[@audiofella5066]

The ones on my macbook pro, two say 15-16, two say 5.1 or so, one says 3.2, two are really high, and two have no reading just say 1 can you say where the short is? This is my first time using a multimeter but i had it set to 200 ohm

[@whoami696]

i have adapter 12v gives volts but no amps, means when i connect my device to adapter no thing and my device ok

[@ΠάριςΑζής]

When the multimeter is put in diode mode, what you see in its display is volts, not ohms...

[@mojikaygaming]

I LEARN ALOT FROM THIS THANK YOU

[@davidjohnson6189]

Ok so basically you test ohms, then if you get bad reading you isolate part (desoldering one side) and if it's low ohms on side that is desoldered it's ok and on other side isolation of part helps pinpoint bad coil, am I right?

[@murmanox5303]

I don't think it's about finding a bad coil as much as it's finding which side of the coil the short circuit is on.

[@ashiq3226]

Is 11ohm short in North bridge ok or not??

[@farzin9421]

Sir, My laptop power port was broken. So I soldered the port. It was running well. But unfortunately for the second time it was broken. I soldered again, may be shorted. :(. Right when I plugged the charger in I noticed a quick and small smoke and a spark on my mother board. I cant find out the faults, I would be very happy if you can help me out.

Did you solved the issue

[@MaxDiegardo]

hey there.. i hve a problem with my laptop - its on top condition but lately been powering off on its own. its getting worse. i try to detect several problems at first it seems like hardware so i check each of them turns out the fan connection to the mobo was a lil bit loose - if i dont press it tightly to the mobo it wont turn but it makes noises. so i changed the fan and thought that it would solve the prob but it happens again. hmm what do you think? i tried pulling out every hardware to try to run the test - seems all is working. (tried them on different laptops too)

[@MaxDiegardo]

thanks for replying! at first the usb board was faulty before the prob happened. i dont really know much - but when it was plugged in the motherboard it wont turn on - it works only after i unplug the usb board. the prob might start from there? gee i dont know - if i detach all hardware including ram and hdd how will i detect the problem? for all i know it might be the motherboard :( buying a new one would cost me about 100$ ... would you recommend how to know which hardware might be faulty? for all i know the hardware includes ram, the keyboard, the system fan , the internet card, the bluetooth card, and the secondary usb board... :D

[@MaxDiegardo]

by the way i recently replaced the system fan and the keyboard with brand new parts

[@MaxDiegardo]

also - the symptoms of the power off problem previously was when i am watching videos. it turns of quickly especially if i watch streaming videos. if i play video from my hard drive it powers off too but not as quickly as when i was streaming. then about a month later it started to power off when i play games! it powers of once or twice then finally it would last me longer - but eventually powers off as well. and then now its gotten much worse - even when its idle and even during sleep it would power off on its own. that much is what i can give you! what do you think?

[@MaxDiegardo]

the heat of the processor and graphics card are alright - it always stays around 60 celcius if im using it for games. other than that, idle state or even doing some work (multimedia or browsing using chrome) it always stays around 40 - 50. checked it using RealTemp and speedfan

[@isaacdzokoto-jnr6306]

thank you so much sir. i have probook 4540s the charger light(orange) blinks 8 times when ever i try to on it

[@teachyourself6839]

hi if the charger light blink when u contacted to laptop that's mean there is shorte in the input voltage for adaptor u need to check Mosfet in the circuit probably one of them short

[@ElTexMexAlex]

Good video, I now I know a coil will have same reading on both sides.

Btw, where do you get Schematic Diagrams? also, where do you get the chips/parts for replacement? Thanks again!

[@ennesimo84]

You find the area of short, not component in short. Please complete the video if you can solve this problem. Thanks

[@linksrepair2851]

hi,thanks very much.This tutorial is the best i have ever watch on how to find short.

[@Toogman]

So where is the short?

[@tomjones4145]

He has no idea apart from it been on the main board lmao

[@joeycarr1398]

Hi, the coil is not soldered?

[@josepeixoto3384]

That is a nice way of doing it, but you did ** not ** find the shorted component yet; part 2 ?

[@josepeixoto3384]

I think the idea of lifting a coil is a god one... *EDIT* TERRIBLE DOUBT»»» the ohmmeter has a 9 (NINE!) volt battery inside and it applies it all in the 200 ohm scale ( ««don't»» touch the probes to your tongue, you'll see,feel,the 9 volts; question: is it safe to probe around those circuits that may be of only 1 volt ,with those probes infected with 9 volts of coronicvirus? thanks

Thanks! I measured my coils and I think its shorted as I get 0V

[@maartenmilis3085]

Thanks, this was helpful. At least I found 1 faulty coil at this moment. I'll check if I can replace it and see if this fixes my problem

[@yaser15784]

according to you is short .... according me...you have to use mbr

I got 16 ohms, is it short or not?

if its cup core voltage path than its not shorting

This really is pretty Stupid. You know initially there is a short. So this then confirms there is a short. Big deal. Then what ?? Throw the motherboard away ? You need to show how to track it down not just confirm there is a short.
