by cassiusI'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.

by debidoobsHello,
im actually trying to save a d1500 delay from yamaha. I found the service manual but schematic is missing and BOM list is a bit unclear as components listed have no reference linked to the pcbs... In my case, one zener diode was broken (114 code on the pcb in attached file) and couldn't be repaired : it was a zener type package. In the BOM list i found 3 reference on this board : 1S555 (can be replaced by 1N4148), RD4.7EB2 (approx 5v rectifier), RD7.5EB3 (approx 7v rectifier)...
Actually the cathode goes to VCC of sram M5M5118P, without this diode missing, i have...-

Hello, Basically a customer tried updating his mini PC using a USB stick but it bricked the computer. I've tried flashing a new chip with a CH318A programmer using neoprogrammer and a ROM file from minisforum's website. From what I have read on the forum here, there isn't a readily available guide on how to serialize an existing bios to the motherboard. I have a dump from the original BIOS chip, I did an additional one and did the fc /b command to make sure no discrepancies were found. The machine model number is Minisforum UM780 XTX, machine serial is MC495UU78XQQMQA0089, Board Serial is F78SD784048A1050804....

by vanromicHello! 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...Today, 06:46 AM -
