Having this very weird issue.
The owner of this laptop complained about screen being intermittent when opening and closing, and has been using the laptop on a thunderbolt video connection since the screen failed.
I swapped with a working screen from an A2141 waiting for parts.
The Os exhibits this weird behavior where it boots to to 1/3 the status bar, then it makes the boop sound. It's at the log in but for whatever reason the desktop isn't loaded.
The laptop boots fine into recovery mode. I updated from Monterey to Sonoma and the laptop still has...04-27-2024, 01:37 PM -
Hello! I'm trying to resuscitate a Macbook that the local tech gave up on. I have the board view and schematic and have the main board out of the case.
Of the 4 usb-c ports, 3 cycle at 5V - they all go up to about 1.5A, then seem to switch off, back to 5V 0A, up to 1.5A, and off again. The cycle lasts a few seconds - maybe 3s.
The 4th port doesn't cycle and draws ~0.5A at 5V consistently. It seems it's the port linked to U3100 - it's on that side of the board and is the port closest to the battery and the CD3215C00 chips.
I've read that the CD3215s are...Yesterday, 06:46 AM -

Hey 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...Yesterday, 05:49 AM -

Hello everyone,
This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.
My patient is an A2338 Macbook Pro M1 (late 2020).
It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...04-22-2024, 06:45 AM

I'm looking for ways to ensure that my desktop computer automatically powers on once the power is restored after an outage. I've heard suggestions about shorting the front panel I/O connector on the motherboard or shorting the SMPS 20/24 pin to accomplish this. However, I'm uncertain if these methods are both effective and safe.Yesterday, 08:38 AM
