Hey, fellow Capacitors JK, JK, My name is chris I am a fairly advanced computer user and abuser and just want to say how much help this site has been to me in the past several years. I have a warning to everyone don't let the capacitors get you

Hello all!
Recently I've got a broken Macbook Air M1 2020 A2337 of eBay with a broken screen and not turning on issue.
After some tinkering I've found C5201 capacitor to be blown. This is where I hit a wall since I am a total noob in this area and have no idea what else to look for. C5201 is on one line with 3 more capacitors which visually seem ok, but beep on continuity mode and also both sides of all capacitors beep when tested with ground from the board. This to me sounds like a short, but I am not able to find what component is before the capacitors to test it.... -
Hi all,
I had recently tried to reflash the bios on a dell latittude that has a Wson8 Chip however to no avail.
My question is, Has anyone had much success using the Pogo/Needle adapters to read and write bios without removing the chip from the main board?
I seem to struggling with the solder process wofh my reflow station and currently have 4 machines waiting for a bios mod/reflash.
For context I have just ordered a EZP2019 SPI flash so this is what I would be using alongside the Pogo Adapter.
Apologies if this is the wrong subcategory.... -
Hello,
I'm desperately trying to get my CH341A to work, but it seems that all my attempts have failed. Despite everything, I want to check that it works, the aim being to read at least one chip and “screenshot” the configuration for me to use as a reference.
Here are the steps (software part):
- I'm running Windows 11 Pro 64-bit (10.0 build 26100)
- Drivers are installed (no error messages) and there are no problems in the Device Manager.
- Set the language to English (to avoid the CH341A's basic software bug)
- Does not work on AsProgrammer... -
Hi
I'm working on a bare 820-2375-A board and I'm still noob if it comes to mac logic boards repair, but slowly getting there.
Board doesn't power up when magsafe is connected, green light on the charger, all G3H and S5 rails are present. I does turns on when I bridge SMC_ONOFF_L pads. Is this normal behaviour for boards from 2008/2009?
Thanks in advance. -
I have this motherboard and it was shorted somewhere on main 19v line...or after...Finally after many desoldering and using boardview and schematic it was shorted mosfet on cpu power rail... Now its all ok but i have two noob questions:
1. Could i have used bench power supply and set it on 19v with 1 amp limit to main 19 v power rail to find what is hot or it would burn something on the way like cpu because it was shorted through the mosfet? I read many articlas and many forums...and some people are saying no,no,no, it is not good idea to use 19v on shorted motherboard on main power...
