Re: Rsmreset
RSMRST#
Its done by SIO Super IO chip EC or KBC what evaaa you wanna call it
In a Compal board before RSMRST# its done there are more stages before but i`ll try to get to the point because EVEN if RSMRST# its done and its pinging the signal to SB (SouthBridge) maybe other problems until there or actually there (Southbridge)
In order to have RSMRST# you have to have all the ALW voltage +3v and +5v , BIOS up and running, (i did not saw or not have to do with something like this but apparently you need it) 32 hz on some Clock (frak me if i now why its there) and then you can see output on SIO.
But if you have 3v and 5v ALW most of the problems or done because if you get those, that means you gave power to chipset, memory, etc
WIFI LAN (boot from lan can power up the pc so it needs to have ALW voltage;same crap)
even now i don`t remember why # is there. I do know that its for a state HI state or LO state like when the voltage is low it triger something or when its High.
You need to be all day with this until your head stop to smell like bacon
Advice: get a few manuals (schematics) on your phone and read them all day.
every day i`m reading them until maybe my head stop to smell :P
AAA almost forgot if i wrote something stupid please tell me i`m still learning and this is what i understood(maybe learn bad
)

I have MSI mpg b560m bazooka motherboard . this motherboard RSMRST# signal missing . i already reprogram bios but same condition
My Motherboard this power stages are ok ...but 3vsb voltage have 4.17v (image added)
VCCRTC ok
RTCRST# ok
ATX_5VSB ok
SIO_3VA ok
3VDSW ok
DPWROK ok
SLP_SUS# ok
VSB_ENABLE# ok
5VDUAL ok
3VSB showing 4.17V
PCH_1P8_VSB ok
PCH_VCCIN_AUX ok
RSMRST# No voltage
this all voltages are ok but RSMRST# voltage is missing i did try to re program bios and change io but same... -
Dear all friends
I am going to read the eeprom inside this printer head i need some help from some expert that work with the canon printers
1. what chip they use inside the head that i mention in title?
2. Is there anyone helping me identifying the pinout
Thanks in advance to all the people that cooperate and Badcaps.net staff.05-26-2025, 06:09 PM -
Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.
I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...11-23-2023, 11:02 PM -
Only 3 years old. Owner said backlight went out and burning smell. Didn't bother plugging in to check if had power LED. Just opened the TV rear and found shorted bridge rectifier diode on the backlight circuit on the PSU. SF26G (400V 2A super fast recovery rectifier link ) diode replace with SF26 (what I had on hand) Google AI said G = Green Components.
Burn looked pretty bad on the board but just was blackened carbon coating material. Scraped and cleaned off quite well and clean solder pad for the new diode.

Over the last several years I've had Android head units in my truck (1995 Ranger), there's been some issues that have always bugged me... or I solved in a less than "ideal" manner. I've designed/ordered PCBs and ordered parts for a board to hopefully fix all of these in a better way, and I'd like to share the design here.
Attached is a .zip of the KiCAD files, Schematic, Gerber Files, and BOM from digikey (ok, it's a downloaded excel of my order I placed, close enough...)
The issues this board corrects are (and what I currently am doing that sucks):
