Gigabyte Ga H270 Gaming 3 Motherboard

rosaprogrammer

Hi,
My Gigabyte GA-H270-Gaming 3 motherboard is faulty so I'one thousand searching for the repair & services guide with electronics schematics to encounter how to gear up it. I'd similar to measure the different chips voltage so if someone could help me find and download the Gigabyte GA-H270-Gaming 3 service manual it would exist slap-up.
My figurer won't turn on anymore, no led when I plug the charger, it stopped suddenly while I was working on it.

Thanks a lot for your help.

Hello and Welcome to the Electronics & Repair Forum

Reddit is your friend. I plant the guide a few days ago posted by a redditor in that location, here is the directly link to his blog. Promise it helps y'all fix your motherboard/laptop as information technology helped me set mine as I have the same one.

Gigabyte GA-H270-Gaming 3 maintenance guide (pdf & fz)

All-time of luck

Edit : I had to complete a quick survey to get the guide and then the PDF appeared + the fz files (boardview files listing all the components on the motherboard'due south pcb), all the others sources I institute online were asking for $$, only download the guide right after the survey and you lot're expert to get.

Hi I also accept this Gigabyte GA-H270-Gaming 3 and I downloaded the services guide to a higher place could you delight tell me how to bank check my motherboard and what to look first exactly? I'm a chip lost when I look at all the measuring points and schematics in the manual. Thanks

You tin start by checking the charging connector soldered on the board y'all should read around 19v, and then check the 2 entry mosfets almost this connector, look for a short circuit past doing a continuity examination with a multimeter.

Downloaded the Gigabyte GA-H270-Gaming 3 maintenance guide higher up, couldn't find it anywhere else for free, cheers for the download link you lot rock bro.

Hi, I go 3v on the beginning pin of the bios chip, and 0v on the pin 8 is that normal?
According to the schematics diagram in the transmission and datasheets, I should take i.8v there, right?
How to check the processor? Is my Gigabyte GA-H270-Gaming three completely dead?
My 3v 5v regulator seems fine though since I tested the voltages and ground. emoji scratching head

I doubtable my Gigabyte GA-H270-Gaming three has a brusk circuit somewhere cause it doesn't outset anymore only I am totally noob and don't know what to begin with, the motherboard looks like a puzzle to me...

I accept a multimeter so I can try to fix it if it's not as well complicated, how can I repair my MB please? I saw you tin purchase mosfets or capacitors and resistances online, fries besides similar the super IO 1, then why not try to repair my figurer myself...

Don't jump into the repair book and chip level right abroad. Depending on the problem it won't exist the same approach. Does your laptop take any consequence with the disply, or the ability? Start with the basics by measuring the voltage at all the measuring points showed in the repair guide, and come dorsum with all the measures then we can help you fix your Gigabyte GA-H270-Gaming 3.

It's important to proceed step past footstep instead of quickly replace parts like RAM or graphics scrap or even the processor, first thing first check if your charger is working. As simple as that. Besides check your bombardment.

And then yous volition go along and check the circuitry : coils, mosfets, capacitors, inductors, etc.

If you are a total beginner in electronics amend have your computer to a repair store to avoid causing more damage to it, fifty-fifty if it costs yous a little scrap. They can solder and desolder parts very quickly without taking any take a chance for the rest of the components.
They tin too simply bank check your Gigabyte GA-H270-Gaming iii and tell you lot what part is causing the problem, and so it will be upward to yous to replace information technology if you prefer doing information technology yourself (a slice of advice when soldering, always use flux or rosin).

I retrieve 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-H270-Gaming 3 repair guide information technology volition help me make the right diagnosis, well I hope and so. I approximate I have some work to practise at present.

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

Check the charging connector. Nearly of the trouble comes from here. Test information technology with a multimeter to run into if yous get the +Vin (DC +nineteen.5v) at its pins.
Locate all the coils on the board and check them for continuity to the ground. (multimeter in diode fashion). These components are the ability supplies of each role of the board, if one power rail is downwardly then it can preclude the laptop from working.
Check all the mosfets on the pcb. At that place are around a dozen, a lot of computers breakdowns come from a curt circuit in a transistor. Mostly the ii chief ones after the charging port, they are very encline to shorts due to their abiding solicitations.
Utilize isopropyl alcohol to locate overheating components. Heat makes it evaporate quicker when put on shorted parts that are very hot.
Finally utilize a voltmeter to check the voltage on components nowadays on the 3v/5v rail, if you don't get the right voltage there then the problem is probably due to the voltage regulating chip, or a failure from a capacitor.
