Originally you'd plug power supply into it and it would take up to 1.2 amps and then drop to 200 milliamps and then go back up again to 1.2, staying all the while at 5 volts. Pressing power button would results in power LED blinking amber 3 times. 3.3 volt rail, 5.1 volt rail present, main power rail 8.8 volts. Power button test pads near EC chip 2.7 volts.
I found a short on the other side:

by MisterAILHi everyone,
Brought a non functionnal PS5. Apparently only a bad PSU...
No beep, nothing.
After some tests i found this :
- PSU is fine (12 volts stable)
- 12 volts line is shorted
- DA9065 was fried, F7003 also => Replaced both of them, short is gone on 12 volts line, no dead short anywhere else.
- By the way, nothing change. No signal, no power, no beep.
Mesuring all rails with my workbench psu (12 volts input)
- 0.00 amp drawing
- 12 volts, 5 volts, 2 volts, 1,15 volts are presents (suppose new DA9065 do is...5 Photos -
by OOF DIO(If anyone has a functional boardview file of FX505DV/DU that would be helpful)
(Had 3 problems, now just 1)
I have no experience or knowledge and usage of tools to repair devices besides the entire past 12-10 days of researching, watching YouTube repair videos and troubleshooting this laptop motherboard. ChatGPT was used as a guide to ask questions.
I used boardviews of mostly FX505GD-M, and some FX505DU, FX505DD. Used schematics of FX505DU.
I had originally intended to replace the BQ24780s first (due to previous battery removal while benchmarking) but I... -
Hey guys,
i've got this laptop from a friend who gave it to me in a dead state.
The laptop wasn't working at all so i've began my search on the 19V power rail.
It was shorted to ground so i injected voltage and the only thing getting hot was my ground clip from my power supply.
I found that the +1.05V Rail for the Chipset was shorted. i removed the coil and it was shorted on the power delivery side.
The pch seems fine bc the rail has over 50 ohms after i removed the coil.
Still nothing was getting hot so i suggested the chip must... -
by mr.DataI have a dead Asus ROG gaming laptop with liquid damage. When I measure the first mosfet, there is 19V. On the second mosfet there is nothing on the input and 4.3V on the output but it is not continuously. It is going up and down.
I have read this article:

Is it through that inductors can never be shorted?
I have 2 inductors near the GPU that are shorted. Does this mean that the GPU itself is shorted? How can I know for sure? - Loading...
