How To Test My Ga 970a Ud3 Motherboard And Repair It

bestjudged

Hello,
My Gigabyte GA-970A-UD3 Rev. 1.0 motherboard is faulty then I'm searching for the repair & services guide with electronics schematics to meet how to prepare it. I'd similar to measure the different fries voltage so if someone could aid me find and download the Gigabyte GA-970A-UD3 Rev. 1.0 service transmission it would be bully.
My computer won't turn on anymore, no led when I plug the charger, it stopped suddenly while I was working on information technology.

Thanks a lot for your help.

Hello and Welcome to the Electronics & Repair Forum

Edit : I had to complete a quick survey to get the guide and so the PDF appeared + the fz files (boardview files listing all the components on the motherboard's pcb), all the others sources I found online were asking for $$, just download the guide correct after the survey and you're good to get.

How-do-you-do I also have this Gigabyte GA-970A-UD3 Rev. 1.0 and I downloaded the services guide above could you delight tell me how to check my motherboard and what to look first exactly? I'chiliad a scrap lost when I await at all the measuring points and schematics in the manual. Cheers

Yous tin can start by checking the charging connector soldered on the board you should read around 19v, and so bank check the 2 entry mosfets most this connector, look for a short circuit past doing a continuity test with a multimeter.
D=Drain pin 5-6-seven-eight
S=Source Pivot i-two-three
1000=Gate Pin4

Downloaded the Gigabyte GA-970A-UD3 Rev. 1.0 maintenance guide above, couldn't find it anywhere else for free, thanks for the download link you rock bro.

Hi, I go 3v on the first pin of the bios scrap, and 0v on the pivot 8 is that normal?
According to the schematics diagram in the manual and datasheets, I should have 1.8v there, right?
How to check the processor? Is my Gigabyte GA-970A-UD3 Rev. 1.0 completely dead?
My 3v 5v regulator seems fine though since I tested the voltages and footing. emoji scratching head

I doubtable my Gigabyte GA-970A-UD3 Rev. 1.0 has a short circuit somewhere cause it doesn't starting time anymore but I am totally noob and don't know what to brainstorm with, the motherboard looks like a puzzle to me...

I have a multimeter so I tin can try to fix information technology if it'south not also complicated, how tin I repair my MB delight? I saw you lot tin buy mosfets or capacitors and resistances online, chips also similar the super IO i, so why not try to repair my computer myself...

Don't leap into the repair volume and chip level correct abroad. Depending on the trouble it won't be the same approach. Does your laptop have whatever issue with the disply, or the ability? Beginning with the nuts by measuring the voltage at all the measuring points showed in the repair guide, and come back with all the measures and so we can help y'all fix your Gigabyte GA-970A-UD3 Rev. 1.0.

It's important to keep step past step instead of quickly replace parts like RAM or graphics chip or even the processor, first thing first check if your charger is working. As simple equally that. Too check your battery.

Then y'all will go on and check the circuitry : coils, mosfets, capacitors, inductors, etc.

If you are a total beginner in electronics better take your figurer to a repair shop to avert causing more harm to it, even if it costs you a petty fleck. They tin can solder and desolder parts very quickly without taking any hazard for the rest of the components.
They can as well but cheque your Gigabyte GA-970A-UD3 Rev. 1.0 and tell you what part is causing the problem, so it will be up to you to replace information technology if you prefer doing information technology yourself (a piece of advice when soldering, always use flux or rosin).

I think I damaged my notebook while flashing the bios, is such a problem even possible? I tried booting from an USB drive with no luck it failed.
I downloaded the Gigabyte GA-970A-UD3 Rev. ane.0 repair guide it will assistance me make the correct diagnosis, well I hope and so. I guess I have some work to do now.

Here are the top 5 things I always do to troubleshoot your faulty MB:

Check the charging connector. Most of the trouble comes from here. Examination information technology with a multimeter to see if you get the +Vin (DC +19.5v) at its pins.
Locate all the coils on the board and check them for continuity to the footing. (multimeter in diode manner). These components are the power supplies of each office of the board, if one ability rail is downward and then it tin can forbid the laptop from working.
Check all the mosfets on the pcb. At that place are effectually a dozen, a lot of computers breakdowns come from a short circuit in a transistor. Generally the 2 primary ones afterwards the charging port, they are very encline to shorts due to their constant solicitations.
Use isopropyl booze to locate overheating components. Rut makes information technology evaporate quicker when put on shorted parts that are very hot.
Finally use a voltmeter to check the voltage on components present on the 3v/5v rail, if y'all don't get the right voltage there so the problem is probably due to the voltage regulating chip, or a failure from a capacitor.
