This resistance on the motherboard is shorted to ground

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, 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... -
I have Asus FA506 ( board DA0BKXMB8D0 Rev: D). Can you please roughly indicate what the lowest resistance I should measure on a coil? I know that a low resistance is allowed on coils in CPU or graphic circuits but can you provide acceptable values of resistance?
Thank you. -
Hello everyone, I have a 645 G9 here with a Ryzen 5 PRO 5675U.
This board has a blown inductor component above the driver chip to the CPU coil, and I am wondering whether the CPU is shorted/dead.
Could anyone please measure the resistance to ground on the leftmost coil/inductor to the CPU?
My resistance value is 2.2 Ohms, which doesn't look good to me.
Thanks to everyone willing to give a value. -
Hello everyone,
I have a question regarding this laptop. Laptop came from my friend, completely dead. No reaction for power button, Adpater etc. Diagnosis: burned HIS mostfet from VRAMs. After replacing the mosfet, Laptop starts to power up, KB lights up for few second and switch off, laptop remain ON but no display. Vents are switching ON after some time. No Caps Lock or reaction on USB stick. No display also through HDMI. All coils resistance seems to be OK except resistance on VRAMs – 15 Ohm ( as I study the other repairs or diagnostic of that laptop it should be around 90 -...03-03-2025, 04:34 PM
