by obelix24I have one strange issue with Macbook Pro 13" A1706 (touch bar) 4 TB ports
Issue is that all 4 ports are working but on one port only one side (when i rotate connector 180 degree there is nothing (ampmeter is not turned on at all) and charger (original apple) is put to protective mode, I have to unplug USB from the power brick to enable it again.
I've tried multiple USB-C ports (one one side all ports all sides work when i reconnect it to other side both ports work but one only on one side)

by krstaHi guys, hope someone could direct me in right way.
So i got the ASUS ROG THOR 1200W PLATINUM for 15€.
The first time i plugged it in wall socket there was no 5VSB present, so i disassembled it took a little peak inside and left it on shelf for a day.
Next day the 5VSB was present and the psu worked the whole day (outside of computer, shorting PS_ON to ground).
I tested it for a few days like than and then installed in my computer, it worked flawlessley for 1 month.(gaming and such for a few hours).

by tccyo22Hey all,
I've got an ASUS laptop (Asus X409DL Rev 2.0) that had a little liquid spill on it however the majority was on the daughter board for the I/O stuff which is connected over a ribbon cable which I have disconnected for now. A small bit of liquid did however get onto what schematics and boardview show is a DC step down IC; a Realtek RT8249CQGW - markings: 2N=. There is no short on the main power rail as I have 19v with the charger plugged in however I have no other power, standby or always on rails anywhere on the board. Looking at the datasheet for this IC I want to sanity...05-01-2024, 05:49 AM

by EazyBoneShown in picture, trying to replace a MOSFET and looks like I knocked this off, in guessing it's the same as one next to it. Has 1.8 Mohms. Any way to bypass it? It's on the hot side

by smaniakThe laptop won't start. When plug power supply, on 19V in gives me 0,14A, without turning on the laptop.
I check it with thermal camera, and there is one resistor that is very hot, I change the resistor with new on but the result is the same.
In the attachment there is schematic of the resistor area, and schematic of the laptop.
I can't understand, why this resistor is getting so hot....05-05-2024, 01:24 AM -
