Hi! May I ask help on this. Im just starting to learn board repairs so I might get terms wrong. The motherboard has 5v standby and can confirm that power on switch is working due to drop of Pin 16 in the 24 pin connector. But no 12v on Pin 10, not even a twitch. Also checked the schematics from the forum. I checked resistance and continuity from the Pin 10 to the components it send 12v to. All of them gives shorted beeps and 0 ohms resistance except an 0 ohm resistor, i guess. It has good continuity and around 0.009 resistance. I attached the screenshot of the board view for the resistor. Thank you for your help!

Hi guys, i was wondering, i've got 9Ohms on Vmem, one of the mosfet was shortet to ground, so i've desoldered hi and low mosfets nad still low res, then i removed all of the memory chips, and the resistance is still low, so did you had maybe a card with that low res on memories, and the card was working fine ?
Removed the U1866Q and still without result, i dont have thermal cam so can't see where is hot spot when incjeting voltage.
The resistance on core is ok 0.1Ohm ((Power 0.8V when on)
Resistance on 12V 4K ohms (Power present when on)
Resistance on 12V PEX 4K ohms... -
Hi masters. can you help me fix this bios?
post moved....next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..... -
Hi,
I discovered a strange behaviour of GIGABYTE GA-H110M-S2 board.
General test conditions:
- Tested with Core i5 6500 and Core I7 6700K - no difference
- Default BIOS settings, but tried also altering several memory setting - does not change anything
What is wrong:
With BIOS F1 and F2 the board normally POST's and boots to Windows 11 with 2 x Patriot Viper Steel PVS416G440C9K RAM (4400MHZ, Samsung B-Die chips)
When BIOS upgraded to anything above F2 (ie. F20-F27b) the board POST stucks after 3 Debug Codes on Code C2... -

Hi, I'm Daniel, and I'm new to the world of repairing motherboards.
I would like to create a table, or more likely a guideline about the voltage rails and their possible resistance rail.
I know that the motherboard design has a very big depend on the rail's resistance, but I would like to know what is the smallest value for a rail that can be acceptable. For example, I heard that some new gaming motherboards can have 0,5 Ohm resistance on the GPU rail, but on an older type, it could be a sign of a shorted GPU rail.
So, I generated a table with AI so I can...
