Re: Need help with ASRock AB350m
I doubt you will find a full-blown schematic - at least I never bother as it's more effort than just "getting on" with the board and testing components.
Regarding the issue: by not turn ON, what do you mean exactly? Nothing happens when you press the power button or do the fans in the PC twitch for a second and PSU go into short-circuit protection?

Hi guys,
I managed to semi-kill an ASRock N100M board after updating Bios from 1.10 to 2.01. It's a zombie now, dead, but not dead.
ASRock N100M special features:
- CPU soldered to board, small Intel 12th gen
- iGPU
- four POST LEDs
Problem after updating Bios to 2.01 using the in-Bios update tool: no picture, no boot.
I am not sure anymore if it booted at least once successfully after updating the bios to 2.01, maybe not, I can't remember. I think it did not.
Symptoms:
- no picture/signal on any of the display connectors,... -
Hi, I’m looking for a clean, working BIOS .bin dump (16MB) for the ASRock B450M Steel Legend motherboard.
I’ve already tried flashing the official ASRock ROM file via CH341A, but it won’t post — I believe the capsule format is incompatible.
Any BIOS version that supports Ryzen 5 2600 is fine (e.g., P2.30–P3.60).
If anyone has a working board and can dump the BIOS using CH341A or flashrom, I would really appreciate your help.
Thank you! -
Hello everyone,
I'm looking for a full BIOS dump (.bin) for the ASRock H310M-HDV Rev 1.02 motherboard. The BIOS chip is a MX25L12873F (128Mb / 16MB).
I’ve already tried flashing the official BIOS from ASRock (version 1.40 and 3.30), but those are Instant Flash versions and don’t include the full SPI image (e.g. Intel ME Region, Descriptor, etc.). After flashing, the board powers on only when I short PS-ON to ground, and it fails to generate Vcore and 2.5V. Other rails like 1.05V and RAM voltage are present.
I suspect the original Intel ME and descriptor... -
Hi,
I have an AsRock B560 Pro4 (boardview: https://www.badcaps.net/forum/troubl...pro4-schematic) that's completely dead (it doesn't even turn on the power supply when the power button is pressed or the power button pins are shorted). I do get about 3.4V on the power button pin, but 1.8VSB isn't there. The resistance to ground on the inductor PL53 is only about 0.1-0.4 Ohms. Am I correct in assuming that there must be a short... -
Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :
(N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
switching supply area).
(N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
than 6.3 V.)
1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
I replaced capacitors with aluminum-polymer.
3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA...
