Hi, I have a faulty motherboard that turns on for 2 seconds and then turns off, I need a schematic to test the voltages to see if anything is missing or out of spec and other things. Laptop model hp14s-dq5002tu Thank you in advance.

Hello,
I have re-soldered the loose pins on the RAM slot which is a common fault on these models..
It charges and turns on the power LED but is missing several voltages like RAM and CPU do not come up which I believe is due to MAINON & SUSON being missing to turn these supplies on..
What I am un-sure of is what is the ITC chip waiting for to send out these signals, what are the requirements?
I have checked these lines in diode mode and they seam normal -> 600.
I have checked to see if they come on for even a fraction of a second... -
Hello
I have Microsoft surface laptop 4, model number 1951. I bought it broken and I'm trying to fix it for myself.
Long story short, I bought it as dead. No voltage on battery, not turning on. I replaced battery and PD controller TPS65993AD and now Surface charges battery and turns on.
The problem is that it shows microsoft logo for 10s and then turns off.
I checked power rails and I'm missing 1P8VSB_EN power rail, it is not turning on because it has missing SLP_SUS
And there is my question, is that more likely related to hardware issue... -

Hello everyone,
I've been encountering some perplexing issues with my ASUS ROG STRIX GTX 1660 Ti Gaming OC and am seeking insights or potential solutions from the community.
Symptoms:
Initially experienced a gradient-style black screen from the top.
Poor performance: ~10 FPS on the lock screen.
Encountered artifacts followed by black screens.
After addressing a PSU-related problem, still observed a performance drop (~10 FPS).
Upon using GPU-Z:
Memory size shows as 0MB.
Unknown bus width and bandwidth reported.... -
Hello
I have a Gigabyte X570 Aorus Pro rev1.0 that doesn't work. I know the motherboard is at fault because the CPU, RAM and power supply have all been tested with a known good motherboard (including after trying them in the faulty board to check it hadn't killed them).
Thanks to some people on this website and elsewhere on the internet, I have a schematic and boardview for the WiFi version of this board, a schematic for the Elite version of this board (same board but cut down on features) and repair guides for other AM4 boards, one of which is for an Asus Tuf Gaming...
