Pleas share ASROCK Q370M Schematic and Board view if available07-18-2025, 02:01 AM -
hello friends, I have a DELL LATITUDE 5420---MODEL P137G, ST 20TFKN3 LA-K491P REV:2.0 (A01) and its quite a challenge. It powers on with the battery disconnected, lasts on for about 15 secs, and then shuts off. It does the same with battery only (no adapter). With battery and adapter it sometimes starts after hitting the button several times. It displays nothing in every case. Since only the Boardview is available, I guided myself with schematics similar to this laptop (I'll add them down).Some measurements:
1- After receiving power SIO_SLP_S0# goes high and never changes.

Hello everyone,
I’m currently working on a project focused on diagnosing and reconstructing the control electronics of RS1 / RS Welding Systems Leipzig (WIG-STEUERUNG) welders.
I’m looking for the schematic diagram or any technical documentation of the main control board labeled 906383 / 906384, used in RS1 TIG/MMA welding machines.
The board includes:- two UBICOM TDS38070 microcontrollers,
- EEPROM 24C256,
- analog ICs such as LM358, TL062, MC33153, MAX4515,
- a gas valve control section (BD135 / IRF8G30 / optocouplers P621),
- connectors labeled Display, Netzteil,

Hello everyone,
I’m looking for the schematic and boardview files specifically for the AMD version of the HP Omen 16 laptop, model xf0006AX, equipped with the Ryzen 7 7840H CPU.
Most of the files I’ve found are for Intel CPU versions, and I need the exact files for this AMD Ryzen 7 7840H model to assist with repair and troubleshooting.
If anyone has access to these files or can kindly share the boardview and schematic for this particular AMD version, I would really appreciate your support.
Thank you very much in advance!

Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:
The schematic...
